from the outset matters little. The main considerations are that with so
favourable a territorial object as Korea limited war was possible in its
most formidable shape, that the war did in fact develop on limited lines,
and that it was entirely successful. Without waiting to secure the command
of the sea, Japan opened by a surprise seizure of Seoul, and then under
cover of minor operations of the fleet proceeded to complete her occupation
of Korea. As she faced the second stage, that of making good the defence of
her conquest, the admirable nature of her geographical object was further
displayed. The theoretical weakness of limited war at this point is the
arrest of your offensive action. But in this case such arrest was neither
necessary nor possible, and for these reasons. To render the conquest
secure not only must the Korean frontier be made inviolable, but Korea must
be permanently isolated by sea. This involved the destruction of the
Russian fleet, and this in its turn entailed the reduction of Port Arthur
by military means. Here, then, in the second stage Japan found herself
committed to two lines of operation with two distinct objectives, Port
Arthur and the Russian army that was slowly concentrating in Manchuria--a
thoroughly vicious situation. So fortunate, however, was the geographical
conformation of the theatre that by promptitude and the bold use of an
uncommanded sea it could be reduced to something far more correct. By
continuing the advance of the Korean army into Manchuria and landing
another force between it and the Port Arthur army the three corps could be
concentrated and the vicious separation of the lines of operations turned
to good account. They could be combined in such a way as to threaten an
enveloping counter-attack on Liao-yang before the Russian offensive
concentration could be completed. Not only was Liao-yang the Russian point
of concentration, but it also was a sound position both for defending Korea
and covering the siege of Port Arthur. Once secured, it gave the Japanese
all the advantages of defence and forced the Russians to exhaust themselves
in offensive operations which were beyond their strength. Nor was it only
ashore that this advantage was gained. The success of the system, which
culminated in the fall of Port Arthur, went further still. Not only did it
make Japan relatively superior at sea, but it enabled her to assume a naval
defensive and so to force the final naval decision on Russia with every
advantage of time, place, and strength in her own favour.
By the battle of Tsushima the territorial object was completely isolated by
sea, and the position of Japan in Korea was rendered as impregnable as that
of Wellington at Torres Vedras. All that remained was to proceed to the
third stage and demonstrate to Russia that the acceptance of the situation
that had been set up was more to her advantage than the further attempt to
break it down. This the final advance to Mukden accomplished, and Japan
obtained her end very far short of having overthrown her enemy. The
offensive power of Russia had never been so strong, while that of Japan was
almost if not quite exhausted.
Approached in this way, the Far Eastern struggle is seen to develop on the
same lines as all our great maritime wars of the past, which continental
strategists have so persistently excluded from their field of study. It
presents the normal three phases--the initial offensive movement to seize
the territorial object, the secondary phase, which forces an attenuated
offensive on the enemy, and the final stage of pressure, in which there is
a return to the offensive "according," as Jomini puts it, "to circumstances
and your relative force in order to obtain the cession desired."
It must not of course be asked that these phases shall be always clearly
defined. Strategical analysis can never give exact results. It aims only at
approximations, at groupings which will serve to guide but will always
leave much to the judgment. The three phases in the Russo-Japanese War,
though unusually well defined, continually overlapped. It must be so; for
in war the effect of an operation is never confined to the limits of its
immediate or primary intention. Thus the occupation of Korea had the
secondary defensive effect of covering the home country, while the initial
blow which Admiral Togo delivered at Port Arthur to cover the primary
offensive movement proved, by the demoralisation it caused in the Russian
fleet, to be a distinct step in the secondary phase of isolating the
conquest. In the later stages of the war the line between what was
essential to set up the second phase of perfecting the isolation and the
third phase of general pressure seems to have grown very nebulous.
It was at this stage that the Japanese strategy has been most severely
criticised, and it was just here they seem to have lost hold of the
conception of a limited war, if in fact they had ever securely grasped the
conception as the elder Pitt understood it. It has been argued that in
their eagerness to deal a blow at the enemy's main army they neglected to
devote sufficient force to reduce Port Arthur, an essential step to
complete the second phase. Whether or not the exigencies of the case
rendered such distribution of force inevitable or whether it was due to
miscalculation of difficulties, the result was a most costly set-back. For
not only did it entail a vast loss of time and life at Port Arthur itself,
but when the sortie of the Russian fleet in June brought home to them their
error, the offensive movement on Liao-yang had to be delayed, and the
opportunity passed for a decisive counter-stroke at the enemy's
concentration ashore.
This misfortune, which was to cost the Japanese so dear, may perhaps be
attributed at least in part to the continental influences under which their
army had been trained. We at least can trace the unlimited outlook in the
pages of the German Staff history. In dealing with the Japanese plan of
operations it is assumed that the occupation of Korea and the isolation of
Port Arthur were but preliminaries to a concentric advance on Liao-yang,
"which was kept in view as the first objective of the operations on land."
But surely on every theory of the war the first objective of the Japanese
on land was Seoul, where they expected to have to fight their first
important action against troops advancing from the Yalu; and surely their
second was Port Arthur, with its fleet and arsenal, which they expected to
reduce with little more difficulty than they had met with ten years before
against the Chinese. Such at least was the actual progression of events,
and a criticism which regards operations of such magnitude and ultimate
importance as mere incidents of strategic deployment is only to be
explained by the domination of the Napoleonic idea of war, against the
universal application of which Clausewitz so solemnly protested. It is the
work of men who have a natural difficulty in conceiving a war plan that
does not culminate in a Jena or a Sedan. It is a view surely which is the
child of theory, bearing no relation to the actuality of the war in
question and affording no explanation of its ultimate success. The truth
is, that so long as the Japanese acted on the principles of limited war, as
laid down by Clausewitz and Jomini and plainly deducible from our own rich
experience, they progressed beyond all their expectations, but so soon as
they departed from them and suffered themselves to be confused with
continental theories they were surprised by unaccountable failure.
The expression "Limited war" is no doubt not entirely happy. Yet no other
has been found to condense the ideas of limited object and limited
interest, which are its special characteristics. Still if the above example
be kept in mind as a typical case, the meaning of the term will not be
mistaken. It only remains to emphasise one important point. The fact that
the doctrine of limited war traverses the current belief that our primary
objective must always be the enemy's armed forces is liable to carry with
it a false inference that it also rejects the corollary that war means the
use of battles. Nothing is further from the conception. Whatever the form
of war, there is no likelihood of our ever going back to the old fallacy of
attempting to decide wars by manoeuvres. All forms alike demand the use of
battles. By our fundamental theory war is always "a continuation of
political intercourse, in which fighting is substituted for writing notes."
However great the controlling influence of the political object, it must
never obscure the fact that it is by fighting we have to gain our end.
It is the more necessary to insist on this point, for the idea of making a
piece of territory your object is liable to be confused with the older
method of conducting war, in which armies were content to manoeuvre for
strategical positions, and a battle came almost to be regarded as a mark of
bad generalship. With such parading limited war has nothing to do. Its
conduct differs only from that of unlimited war in that instead of having
to destroy our enemy's whole power of resistance, we need only overthrow so
much of his active force as he is able or willing to bring to bear in order
to prevent or terminate our occupation of the territorial object.
The first consideration, then, in entering on such a war is to endeavour to
determine what the force will amount to. It will depend, firstly, on the
importance the enemy attaches to the limited object, coupled with the
nature and extent of his preoccupations elsewhere, and, secondly, it will
depend upon the natural difficulties of his lines of communication and the
extent to which we can increase those difficulties by our conduct of the
initial operations. In favourable circumstances therefore (and here lies
the great value of the limited form) we are able to control the amount of
force we shall have to encounter. The most favourable circumstances and the
only circumstances by which we ourselves can profit are such as permit the
more or less complete isolation of the object by naval action, and such
isolation can never be established until we have entirely overthrown the
enemy's naval forces.
Here, then, we enter the field of naval strategy. We can now leave behind
us the theory of war in general and, in order to pave the way to our final
conclusions, devote our attention to the theory of naval warfare in
particular.

PART TWO
THEORY OF NAVAL WAR
* * * * *
CHAPTER ONE
THEORY OF THE OBJECT--
COMMAND OF THE SEA
* * * * *
The object of naval warfare must always be directly or indirectly either to
secure the command of the sea or to prevent the enemy from securing it.
The second part of the proposition should be noted with special care in
order to exclude a habit of thought, which is one of the commonest sources
of error in naval speculation. That error is the very general assumption
that if one belligerent loses the command of the sea it passes at once to
the other belligerent. The most cursory study of naval history is enough to
reveal the falseness of such an assumption. It tells us that the most
common situation in naval war is that neither side has the command; that
the normal position is not a commanded sea, but an uncommanded sea. The
mere assertion, which no one denies, that the object of naval warfare is to
get command of the sea actually connotes the proposition that the command
is normally in dispute. It is this state of dispute with which naval
strategy is most nearly concerned, for when the command is lost or won pure
naval strategy comes to an end.
This truth is so obvious that it would scarcely be worth mentioning were it
not for the constant recurrence of such phrases as: "If England were to
lose command of the sea, it would be all over with her." The fallacy of the
idea is that it ignores the power of the strategical defensive. It assumes
that if in the face of some extraordinary hostile coalition or through some
extraordinary mischance we found ourselves without sufficient strength to
keep the command, we should therefore be too weak to prevent the enemy
getting it--a negation of the whole theory of war, which at least requires
further support than it ever receives.
And not only is this assumption a negation of theory; it is a negation both
of practical experience and of the expressed opinion of our greatest
masters. We ourselves have used the defensive at sea with success, as under
William the Third and in the War of American Independence, while in our
long wars with France she habitually used it in such a way that sometimes
for years, though we had a substantial preponderance, we could not get
command, and for years were unable to carry out our war plan without
serious interruption from her fleet.
So far from the defensive being a negligible factor at sea, or even the
mere pestilent heresy it is generally represented, it is of course inherent
in all war, and, as we have seen, the paramount questions of strategy both
at sea and on land turn on the relative possibilities of offensive and
defensive, and upon the relative proportions in which each should enter
into our plan of war. At sea the most powerful and aggressively-minded
belligerent can no more avoid his alternating periods of defence, which
result from inevitable arrests of offensive action, than they can be
avoided on land. The defensive, then, has to be considered; but before we
are in a position to do so with profit, we have to proceed with our
analysis of the phrase, "Command of the Sea," and ascertain exactly what it
is we mean by it in war.
In the first place, "Command of the Sea" is not identical in its
strategical conditions with the conquest of territory. You cannot argue
from the one to the other, as has been too commonly done. Such phrases as
the "Conquest of water territory" and "Making the enemy's coast our
frontier" had their use and meaning in the mouths of those who framed them,
but they are really little but rhetorical expressions founded on false
analogy, and false analogy is not a secure basis for a theory of war.
The analogy is false for two reasons, both of which enter materially into
the conduct of naval war. You cannot conquer sea because it is not
susceptible of ownership, at least outside territorial waters. You cannot,
as lawyers say, "reduce it into possession," because you cannot exclude
neutrals from it as you can from territory you conquer. In the second
place, you cannot subsist your armed force upon it as you can upon enemy's
territory. Clearly, then, to make deductions from an assumption that
command of the sea is analogous to conquest of territory is unscientific,
and certain to lead to error.
The only safe method is to inquire what it is we can secure for ourselves,
and what it is we can deny the enemy by command of the sea. Now, if we
exclude fishery rights, which are irrelevant to the present matter, the
only right we or our enemy can have on the sea is the right of passage; in
other words, the only positive value which the high seas have for national
life is as a means of communication. For the active life of a nation such
means may stand for much or it may stand for little, but to every maritime
State it has some value. Consequently by denying an enemy this means of
passage we check the movement of his national life at sea in the same kind
of way that we check it on land by occupying his territory. So far the
analogy holds good, but no further.
So much for the positive value which the sea has in national life. It has
also a negative value. For not only is it a means of communication, but,
unlike the means of communication ashore, it is also a barrier. By winning
command of the sea we remove that barrier from our own path, thereby
placing ourselves in position to exert direct military pressure upon the
national life of our enemy ashore, while at the same time we solidify it
against him and prevent his exerting direct military pressure upon
ourselves.
Command of the sea, therefore, means nothing but the control of maritime
communications, whether for commercial or military purposes. The object of
naval warfare is the control of communications, and not, as in land
warfare, the conquest of territory. The difference is fundamental. True, it
is rightly said that strategy ashore is mainly a question of
communications, but they are communications in another sense. The phrase
refers to the communications of the army alone, and not to the wider
communications which are part of the life of the nation.
But on land also there are communications of a kind which are essential to
national life--the internal communications which connect the points of
distribution. Here again we touch an analogy between the two kinds of war.
Land warfare, as the most devoted adherents of the modern view admit,
cannot attain its end by military victories alone. The destruction of your
enemy's forces will not avail for certain unless you have in reserve
sufficient force to complete the occupation of his inland communications
and principal points of distribution. This power is the real fruit of
victory, the power to strangle the whole national life. It is not until
this is done that a high-spirited nation, whose whole heart is in the war,
will consent to make peace and do your will. It is precisely in the same
way that the command of the sea works towards peace, though of course in a
far less coercive manner, against a continental State. By occupying her
maritime communications and closing the points of distribution in which
they terminate we destroy the national life afloat, and thereby check the
vitality of that life ashore so far as the one is dependent on the other.
Thus we see that so long as we retain the power and right to stop maritime
communications, the analogy between command of the sea and the conquest of
territory is in this aspect very close. And the analogy is of the utmost
practical importance, for on it turns the most burning question of maritime
war, which it will be well to deal with in this place.
It is obvious that if the object and end of naval warfare is the control of
communications it must carry with it the right to forbid, if we can, the
passage of both public and private property upon the sea. Now the only
means we have of enforcing such control of commercial communications at sea
is in the last resort the capture or destruction of sea-borne property.
Such capture or destruction is the penalty which we impose upon our enemy
for attempting to use the communications of which he does not hold the
control. In the language of jurisprudence, it is the ultimate sanction of
the interdict which we are seeking to enforce. The current term "Commerce
destruction" is not in fact a logical expression of the strategical idea.
To make the position clear we should say "Commerce prevention."
The methods of this "Commerce prevention" have no more connection with the
old and barbarous idea of plunder and reprisal than orderly requisitions
ashore have with the old idea of plunder and ravaging. No form of war
indeed causes so little human suffering as the capture of property at sea.
It is more akin to process of law, such as distress for rent, or execution
of judgment, or arrest of a ship, than to a military operation. Once, it is
true, it was not so. In the days of privateers it was accompanied too
often, and particularly in the Mediterranean and the West Indies, with
lamentable cruelty and lawlessness, and the existence of such abuses was
the real reason for the general agreement to the Declaration of Paris by
which privateering was abolished.
But it was not the only reason. The idea of privateering was a survival of
a primitive and unscientific conception of war, which was governed mainly
by a general notion of doing your enemy as much damage as possible and
making reprisal for wrongs he had done you. To the same class of ideas
belonged the practice of plunder and ravaging ashore. But neither of these
methods of war was abolished for humanitarian reasons. They disappeared
indeed as a general practice before the world had begun to talk of
humanity. They were abolished because war became more scientific. The right
to plunder and ravage was not denied. But plunder was found to demoralise
your troops and unfit them for fighting, and ravaging proved to be a less
powerful means of coercing your enemy than exploiting the occupied country
by means of regular requisitions for the supply of your own army and the
increase of its offensive range. In short, the reform arose from a desire
to husband your enemy's resources for your own use instead of wantonly
wasting them.
In a similar way privateering always had a debilitating effect upon our own
regular force. It greatly increased the difficulty of manning the navy, and
the occasional large profits had a demoralising influence on detached
cruiser commanders. It tended to keep alive the mediaeval corsair spirit at
the expense of the modern military spirit which made for direct operations
against the enemy's armed forces. It was inevitable that as the new
movement of opinion gathered force it should carry with it a conviction
that for operating against sea-borne trade sporadic attack could never be
so efficient as an organised system of operations to secure a real
strategical control of the enemy's maritime communications. A riper and
sounder view of war revealed that what may be called tactical commercial
blockade--that is, the blockade of ports--could be extended to and
supplemented by a strategical blockade of the great trade routes. In moral
principle there is no difference between the two. Admit the principle of
tactical or close blockade, and as between belligerents you cannot condemn
the principle of strategical or distant blockade. Except in their effect
upon neutrals, there is no juridical difference between the two.
Why indeed should this humane yet drastic process of war be rejected at sea
if the same thing is permitted on land? If on land you allow contributions
and requisitions, if you permit the occupation of towns, ports, and inland
communications, without which no conquest is complete and no effective war
possible, why should you refuse similar procedure at sea where it causes
far less individual suffering? If you refuse the right of controlling
communications at sea, you must also refuse the right on land. If you admit
the right of contributions on land, you must admit the right of capture at
sea. Otherwise you will permit to military Powers the extreme rights of war
and leave to the maritime Powers no effective rights at all. Their ultimate
argument would be gone.
In so far as the idea of abolishing private capture at sea is humanitarian,
and in so far as it rests on a belief that it would strengthen our position
as a commercial maritime State, let it be honourably dealt with. But so far
as its advocates have as yet expressed themselves, the proposal appears to
be based on two fallacies. One is, that you can avoid attack by depriving
yourself of the power of offence and resting on defence alone, and the
other, the idea that war consists entirely of battles between armies or
fleets. It ignores the fundamental fact that battles are only the means of
enabling you to do that which really brings wars to an end-that is, to
exert pressure on the citizens and their collective life. "After shattering
the hostile main army," says Von der Goltz, "we still have the forcing of a
peace as a separate and, in certain circumstances, a more difficult task
... to make the enemy's country feel the burdens of war with such weight
that the desire for peace will prevail. This is the point in which Napoleon
failed.... It may be necessary to seize the harbours, commercial centres,
important lines of traffic, fortifications and arsenals, in other words,
all important property necessary to the existence of the people and army."
If, then, we are deprived of the right to use analogous means at sea, the
object for which we fight battles almost ceases to exist. Defeat the
enemy's fleets as we may, he will be but little the worse. We shall have
opened the way for invasion, but any of the great continental Powers can
laugh at our attempts to invade single-handed. If we cannot reap the
harvest of our success by deadening his national activities at sea, the
only legitimate means of pressure within our strength will be denied us.
Our fleet, if it would proceed with such secondary operations as are
essential for forcing a peace, will be driven to such barbarous expedients
as the bombardment of seaport towns and destructive raids upon the hostile
coasts.
If the means of pressure which follow successful fighting were abolished
both on land and sea there would be this argument in favour of the change,
that it would mean perhaps for civilised States the entire cessation of
war; for war would become so impotent, that no one would care to engage in
it. It would be an affair between regular armies and fleets, with which the
people had little concern. International quarrels would tend to take the
form of the mediaeval private disputes which were settled by champions in
trial by battle, an absurdity which led rapidly to the domination of purely
legal procedure. If international quarrels could go the same way, humanity
would have advanced a long stride. But the world is scarcely ripe for such
a revolution. Meanwhile to abolish the right of interference with the flow
of private property at sea without abolishing the corresponding right
ashore would only defeat the ends of humanitarians. The great deterrent,
the most powerful check on war, would be gone. It is commerce and finance
which now more than ever control or check the foreign policy of nations. If
commerce and finance stand to lose by war, their influence for a peaceful
solution will be great; and so long as the right of private capture at sea
exists, they stand to lose in every maritime war immediately and inevitably
whatever the ultimate result may be. Abolish the right, and this deterrent
disappears; nay, they will even stand to win immediate gains owing to the
sudden expansion of Government expenditure which the hostilities will
entail, and the expansion of sea commerce which the needs of the armed
forces will create. Any such losses as maritime warfare under existing
conditions must immediately inflict will be remote if interference with
property is confined to the land. They will never indeed be serious except
in the case of complete defeat, and no one enters upon war expecting
defeat. It is in the hope of victory and gain that aggressive wars are
born. The fear of quick and certain loss is their surest preventive.
Humanity, then, will surely beware how in a too hasty pursuit of peaceful
ideals it lets drop the best weapon it has for scotching the evil it has as
yet no power to kill.
In what follows, therefore, it is intended to regard the right of private
capture at sea as still subsisting. Without it, indeed, naval warfare is
almost inconceivable, and in any case no one has any experience of such a
truncated method of war on which profitable study can be founded.
The primary method, then, in which we use victory or preponderance at sea
and bring it to bear on the enemy's population to secure peace, is by the
capture or destruction of the enemy's property, whether public or private.
But in comparing the process with the analogous occupation of territory and
the levying of contributions and requisitions we have to observe a marked
difference. Both processes are what may be called economic pressure. But
ashore the economic pressure can only be exerted as the consequence of
victory or acquired domination by military success. At sea the process
begins at once. Indeed, more often than not, the first act of hostility in
maritime wars has been the capture of private property at sea. In a sense
this is also true ashore. The first step of an invader after crossing the
frontier will be to control to a less or greater extent such private
property as he is able to use for his purposes. But such interference with
private property is essentially a military act, and does not belong to the
secondary phase of economic pressure. At sea it does, and the reason why
this should be so lies in certain fundamental differences between land and
sea warfare which are implicit in the communication theory of naval war.
To elucidate the point, it must be repeated that maritime communications,
which are the root of the idea of command of the sea, are not analogous to
military communications in the ordinary use of the term. Military
communications refer solely to the army's lines of supply and retreat.
Maritime communications have a wider meaning. Though in effect embracing
the lines of fleet supply, they correspond in strategical values not to
military lines of supply, but to those internal lines of communication by
which the flow of national life is maintained ashore. Consequently maritime
communications are on a wholly different footing from land communications.
At sea the communications are, for the most part, common to both
belligerents, whereas ashore each possesses his own in his own territory.
The strategical effect is of far-reaching importance, for it means that at
sea strategical offence and defence tend to merge in a way that is unknown
ashore. Since maritime communications are common, we as a rule cannot
attack those of the enemy without defending our own. In military operations
the converse is the rule. Normally, an attack on our enemy's communications
tends to expose their own.
The theory of common communications will become clear by taking an example.
In our wars with France our communications with the Mediterranean, India,
and America ran down from the Channel mouth past Finisterre and St.
Vincent; and those of France, at least from her Atlantic ports, were
identical for almost their entire distance. In our wars with the Dutch the
identity was even closer. Even in the case of Spain, her great trade routes
followed the same lines as our own for the greater part of their extent.
Consequently the opening moves which we generally made to defend our trade
by the occupation of those lines placed us in a position to attack our
enemy's trade. The same situation arose even when our opening dispositions
were designed as defence against home invasion or against attacks upon our
colonies, for the positions our fleet had to take up to those ends always
lay on or about the terminal and focal points of trade routes. Whether our
immediate object were to bring the enemy's main fleets to action or to
exercise economic pressure, it made but little difference. If the enemy
were equally anxious to engage, it was at one of the terminal or focal
areas we were almost certain to get contact. If he wished to avoid a
decision, the best way to force him to action was to occupy his trade
routes at the same vital points.
Thus it comes about that, whereas on land the process of economic pressure,
at least in the modern conception of war, should only begin after decisive
victory, at sea it starts automatically from the first. Indeed such
pressure may be the only means of forcing the decision we seek, as will
appear more clearly when we come to deal with the other fundamental
difference between land and sea warfare.
Meanwhile we may note that at sea the use of economic pressure from the
commencement is justified for two reasons. The first is, as we have seen,
that it is an economy of means to use our defensive positions for attack
when attack does not vitiate those positions, and it will not vitiate them
if fleet cruisers operate with restraint. The second is, that interference
with the enemy's trade has two aspects. It is not only a means of exerting
the secondary economic pressure, it is also a primary means towards
overthrowing the enemy's power of resistance. Wars are not decided
exclusively by military and naval force. Finance is scarcely less
important. When other things are equal, it is the longer purse that wins.
It has even many times redressed an unfavourable balance of armed force and
given victory to the physically weaker Power. Anything, therefore, which we
are able to achieve towards crippling our enemy's finance is a direct step
to his overthrow, and the most effective means we can employ to this end
against a maritime State is to deny him the resources of seaborne trade.
It will be seen, therefore, that in naval warfare, however closely we may
concentrate our efforts on the destruction of our enemy's armed forces as
the direct means to his overthrow, it would be folly to stay our hands when
opportunities occur, as they will automatically, for undermining his
financial position on which the continued vigour of those armed forces so
largely depends. Thus the occupation of our enemy's sea communications and
the confiscatory operations it connotes are in a sense primary operations,
and not, as on land, secondary.
Such, then, are the abstract conclusions at which we arrive in our attempt
to analyse the idea of command of the sea and to give it precision as the
control of common communications. Their concrete value will appear when we
come to deal with the various forms which naval operations may take, such
as, "seeking out the enemy's fleet," blockade, attack and defence of trade,
and the safeguarding of combined expeditions. For the present it remains to
deal with the various kinds of sea command which flow from the
communication idea.
If the object of the command of the sea is to control communications, it is
obvious it may exist in various degrees. We may be able to control the
whole of the common communications as the result either of great initial
preponderance or of decisive victory. If we are not sufficiently strong to
do this, we may still be able to control some of the communications; that
is, our control may be general or local. Obvious as the point is, it needs
emphasising, because of a maxim that has become current that "the sea is
all one." Like other maxims of the kind, it conveys a truth with a trail of
error in its wake. The truth it contains seems to be simply this, that as a
rule local control can only avail us temporarily, for so long as the enemy
has a sufficient fleet anywhere, it is theoretically in his power to
overthrow our control of any special sea area.
It amounts indeed to little more than a rhetorical expression, used to
emphasise the high mobility of fleets as contrasted with that of armies and
the absence of physical obstacles to restrict that mobility. That this
vital feature of naval warfare should be consecrated in a maxim is well,
but when it is caricatured into a doctrine, as it sometimes is, that you
cannot move a battalion oversea till you have entirely overthrown your
enemy's fleet, it deserves gibbeting. It would be as wise to hold that in
war you must never risk anything.
It would seem to have been the evil influence of this travestied maxim
which had much to do with the cramped and timorous strategy of the
Americans in their late war with Spain. They had ample naval force to
secure such a local and temporary command of the Gulf of Mexico as to have
justified them at once in throwing all the troops they had ready into Cuba
to support the insurgents, in accordance with their war plan. They had also
sufficient strength to ensure that the communications with the
expeditionary force could not be interrupted permanently. And yet, because
the Spaniards had an undefeated fleet at sea somewhere, they hesitated, and
were nearly lost. The Japanese had no such illusions. Without having struck
a naval blow of any kind, and with a hostile fleet actually within the
theatre of operations, they started their essential military movement
oversea, content that though they might not be able to secure the control
of the line of passage, they were in a position to deny effective control
to the enemy. Our own history is full of such operations. There are cases
in plenty where the results promised by a successful military blow oversea,
before permanent command had been obtained, were great enough to justify a
risk which, like the Japanese, we knew how to minimise by judicious use of
our favourable geographical position, and of a certain system of
protection, which must be dealt with later.
For the purpose, then, of framing a plan of war or campaign, it must be
taken that command may exist in various states or degrees, each of which
has its special possibilities and limitations. It may be general or local,
and it may be permanent or temporary. General command may be permanent or
temporary, but mere local command, except in very favourable geographical
conditions, should scarcely ever be regarded as more than temporary, since
normally it is always liable to interruption from other theatres so long as
the enemy possesses an effective naval force.
Finally, it has to be noted that even permanent general command can never
in practice be absolute. No degree of naval superiority can ensure our
communications against sporadic attack from detached cruisers, or even
raiding squadrons if they be boldly led and are prepared to risk
destruction. Even after Hawke's decisive victory at Quiberon had completed
the overthrow of the enemy's sea forces, a British transport was captured
between Cork and Portsmouth, and an Indiaman in sight of the Lizard, while
Wellington's complaints in the Peninsula of the insecurity of his
communications are well known.[9] By general and permanent control we do
not mean that the enemy can do nothing, but that he cannot interfere with
our maritime trade and oversea operations so seriously as to affect the
issue of the war, and that he cannot carry on his own trade and operations
except at such risk and hazard as to remove them from the field of
practical strategy. In other words, it means that the enemy can no longer
attack our lines of passage and communication effectively, and that he
cannot use or defend his own.
[9] In justice to Wellington, it should be said that his complaints were
due to false reports that exaggerated a couple of insignificant captures
into a serious interruption.
To complete our equipment for appreciating any situation for which
operations have to be designed, it is necessary to remember that when the
command is in dispute the general conditions may give a stable or an
unstable equilibrium. It may be that the power of neither side
preponderates to any appreciable extent. It may also be that the
preponderance is with ourselves, or it may be that it lies with the enemy.
Such preponderance of course will not depend entirely on actual relative
strength, either physical or moral, but will be influenced by the
inter-relation of naval positions and the comparative convenience of their
situation in regard to the object of the war or campaign. By naval
positions we mean, firstly, naval bases and, secondly, the terminals of the
greater lines of communication or trade-routes and the focal areas where
they tend to converge, as at Finisterre, Gibraltar, Suez, the Cape,
Singapore, and many others.
Upon the degree and distribution of this preponderance will depend in a
general way the extent to which our plans will be governed by the idea of
defence or offence. Generally speaking, it will be to the advantage of the
preponderating side to seek a decision as quickly as possible in order to
terminate the state of dispute. Conversely, the weaker side will as a rule
seek to avoid or postpone a decision in hope of being able by minor
operations, the chances of war, or the development of fresh strength, to
turn the balance in its favour. Such was the line which France adopted
frequently in her wars with us, sometimes legitimately, but sometimes to
such an excess as seriously to demoralise her fleet. Her experience has led
to a hasty deduction that the defensive at sea for even a weaker Power is
an unmixed evil. Such a conclusion is foreign to the fundamental principles
of war. It is idle to exclude the use of an expectant attitude because in
itself it cannot lead to final success, and because if used to excess it
ends in demoralisation and the loss of will to attack. The misconception
appears to have arisen from insistence on the drawbacks of defence by
writers seeking to persuade their country to prepare in time of peace
sufficient naval strength to justify offence from the outset.
Having now determined the fundamental principles which underlie the idea of
Command of the Sea, we are in a position to consider the manner in which
fleets are constituted in order to fit them for their task.

CHAPTER TWO
* * * * *
THEORY OF THE MEANS--
THE CONSTITUTION OF FLEETS
* * * * *
In all eras of naval warfare fighting ships have exhibited a tendency to
differentiate into groups in accordance with the primary function each
class was designed to serve. These groupings or classifications are what is
meant by the constitution of a fleet. A threefold differentiation into
battleships, cruisers, and flotilla has so long dominated naval thought
that we have come to regard it as normal, and even essential. It may be so,
but such a classification has been by no means constant. Other ideas of
fleet constitution have not only existed, but have stood the test of war
for long periods, and it is unscientific and unsafe to ignore such facts if
we wish to arrive at sound doctrine.
The truth is, that the classes of ships which constitute a fleet are, or
ought to be, the expression in material of the strategical and tactical
ideas that prevail at any given time, and consequently they have varied not
only with the ideas, but also with the material in vogue. It may also be
said more broadly that they have varied with the theory of war, by which
more or less consciously naval thought was dominated. It is true that few
ages have formulated a theory of war, or even been clearly aware of its
influence; but nevertheless such theories have always existed, and even in
their most nebulous and intangible shapes seem to have exerted an
ascertainable influence on the constitution of fleets.
Going back to the dawn of modern times, we note that at the opening of the
sixteenth century, when galley warfare reached its culmination, the
constitution was threefold, bearing a superficial analogy to that which we
have come to regard as normal. There were the galeasses and heavy galleys
corresponding to our battleships, light galleys corresponding to our
cruisers, while the flotilla was represented by the small "frigates,"
"brigantines," and similar craft, which had no slave gang for propulsion,
but were rowed by the fighting crew. Such armed sailing ships as then
existed were regarded as auxiliaries, and formed a category apart, as
fireships and bomb-vessels did in the sailing period, and as mine-layers do
now. But the parallel must not be overstrained. The distinction of function
between the two classes of galleys was not so strongly marked as that
between the lighter craft and the galleys; that is to say, the scientific
differentiation between battleships and cruisers had not yet been so firmly
developed as it was destined to become in later times, and the smaller
galleys habitually took their place in the fighting line.
With the rise of the sailing vessel as the typical ship-of-war an entirely
new constitution made its appearance. The dominating classification became
twofold. It was a classification into vessels of subservient movement using
sails, and vessels of free movement using oars. It was on these lines that
our true Royal Navy was first organised by Henry the Eighth, an expert who,
in the science of war, was one of the most advanced masters in Europe. In
this constitution there appears even less conception than in that of the
galley period of a radical distinction between battleships and cruisers. As
Henry's fleet was originally designed, practically the whole of the
battleships were sailing vessels, though it is true that when the French
brought up galleys from the Mediterranean, he gave some of the smartest of
them oars. The constitution was in fact one of battleships and flotilla. Of
cruisers there were none as we understand them. Fleet scouting was done by
the "Row-barges" and newly introduced "Pinnaces" of the flotilla, while as
for commerce protection, merchant vessels had usually to look after
themselves, the larger ones being regularly armed for their own defence.
The influence of this twofold constitution continued long after the
conditions of its origin had passed away. In ever-lessening degree indeed
it may be said to have lasted for two hundred years. During the Dutch wars
of the seventeenth century, which finally established the dominant status
of the sailing warship, practically all true sailing vessels--that is,
vessels that had no auxiliary oar propulsion--took station in the line. The
"Frigates" of that time differed not at all from the "Great Ship" in their
functions, but only in their design. By the beginning of the eighteenth
century, however, the old tendency to a threefold organisation began to
reassert itself, but it was not till the middle of the century that the
process of development can be regarded as complete.
Down to the end of the War of the Austrian Succession--a period which is
usually deemed to be one of conspicuous depression in the naval art--the
classification of our larger sailing vessels was purely arbitrary. The
"Rates" (which had been introduced during the Dutch wars) bore no relation
to any philosophical conception of the complex duties of a fleet. In the
first rate were 100-gun ships; in the second, 90-gun ships--all
three-deckers. So far the system of rating was sound enough, but when we
come to the third rate we find it includes 80-gun ships, which were also of
three decks, while the bulk of the rest were 70-gun two-deckers. The fourth
rate was also composed of two-decked ships--weak battle-units of 60 and 50
guns--and this was far the largest class. All these four rates were classed
as ships-of-the-line. Below them came the fifth rates, which, though they
were used as cruisers, had no distinct class name. They differed indeed
only in degree from the ship-of-the-line, being all cramped two-deckers of
44 and 40 guns, and they must be regarded, in so far as they expressed any
logical idea of naval warfare, as the forerunners of the "Intermediate"
class, represented in the succeeding epochs by 50-gun ships, and in our own
time by armoured cruisers. The only true cruiser is found in the sixth
rate, which comprised small and weakly armed 20-gun ships, and between them
and the "Forties" there was nothing. Below them, but again without any
clear differentiation, came the unrated sloops representing the flotilla.
In such a system of rating there is no logical distinction either between
large and small battleships or between battleships and cruisers, or between
cruisers and flotilla. The only marked break in the gradual descent is that
between the 40-gun two-deckers and the 20-gun cruisers. As these latter
vessels as well as the sloops used sweeps for auxiliary propulsion, we are
forced to conclude that the only basis of the classification was that
adopted by Henry the Eighth, which, sound as it was in his time, had long
ceased to have any real relation to the actuality of naval war.
It was not till Anson's memorable administration that a scientific system
of rating was re-established and the fleet at last assumed the logical
constitution which it retained up to our own time. In the first two rates
appear the fleet flagship class, three-deckers of 100 and 90 guns
respectively. All smaller three-deckers are eliminated. In the next two
rates we have the rank and file of the battle-line, two-deckers of
increased size-namely, seventy-fours in the third rate, and sixty-fours in
the fourth. Here, however, is a slight break in the perfection of the
system, for the fourth rate also included 50-gun ships of two decks, which,
during the progress of the Seven Years' War, ceased to be regarded as
ships-of-the-line. War experience was eliminating small battleships, and
therewith it called for a type intermediate between battleships and
cruisers, with whose functions we shall have to deal directly. In practice
these units soon formed a rate by themselves, into which, by the same
tendency, 60-gun ships were destined to sink half a century later.
But most pregnant of all Anson's reforms was the introduction of the true
cruiser, no longer a small battleship, but a vessel specialised for its
logical functions, and distinct in design both from the battle rates and
the flotilla. Both 40-gun and 20-gun types were abolished, and in their
place appear two cruiser rates, and the fifth consisting of 32-gun true
frigates, and the sixth of 28-gun frigates, both completely divorced from
any battle function. Finally, after a very distinct gap, came the unrated
sloops and smaller craft, which formed the flotilla for coastwise and
inshore work, despatch service, and kindred duties.
The reforms of the great First Lord amounted in fact to a clearly
apprehended threefold constitution, in which the various groups were
frankly specialised in accordance with the functions each was expected to
perform. Specialisation, it will be observed, is the note of the process of
development. We have no longer an endeavour to adapt the fleet to its
multifarious duties by multiplying a comparatively weak nature of
fighting-ship, which could act in the line and yet be had in sufficient
numbers to protect commerce, but which was not well fitted for either
service. Instead we note a definite recognition of the principle that
battleships should be as powerful as possible, and that in order to permit
of their due development they must be relieved of their cruising functions
by a class of vessel specially adapted for the purpose. The question we
have to consider is, was this specialisation, which has asserted itself
down to our own times, in the true line of development? Was it, in fact, a
right expression of the needs which are indicated by the theory of naval
war?
By the theory of naval war it must be reiterated we mean nothing but an
enunciation of the fundamental principles which underlie all naval war.
Those principles, if we have determined them correctly, should be found
giving shape not only to strategy and tactics, but also to material,
whatever method and means of naval warfare may be in use at any given time.
Conversely, if we find strategy, tactics, or organisation exhibiting a
tendency to reproduce the same forms under widely differing conditions of
method and material, we should be able to show that those forms bear a
constant and definite relation to the principles which our theory
endeavours to express.
In the case of Anson's threefold organisation, the relation is not far to
seek, though it has become obscured by two maxims. The one is, that "the
command of the sea depends upon battleships," and the other, that "cruisers
are the eyes of the fleet." It is the inherent evil of maxims that they
tend to get stretched beyond their original meaning. Both of these express
a truth, but neither expresses the whole truth. On no theory of naval
warfare can we expect to command the sea with battleships, nor, on the
communication theory, can we regard the primary function of cruisers as
being to scout for a battle-fleet. It is perfectly true that the control
depends ultimately on the battle-fleet if control is disputed by a hostile
battle-fleet, as it usually is. It is also true that, so far as is
necessary to enable the battle-fleet to secure the control, we have to
furnish it with eyes from our cruiser force. But it does not follow that
this is the primary function of cruisers. The truth is, we have to withdraw
them from their primary function in order to do work for the battle-fleet
which it cannot do for itself.
Well established as is the "Eyes of the fleet" maxim, it would be very
difficult to show that scouting was ever regarded as the primary function
of cruisers by the highest authorities. In Nelson's practice at least their
paramount function was to exercise the control which he was securing with
his battle-squadron. Nothing is more familiar in naval history than his
incessant cry from the Mediterranean for more cruisers, but the
significance of that cry has become obscured. It was not that his cruisers
were not numerous in proportion to his battleships--they were usually
nearly double in number--but it was rather that he was so deeply convinced
of their true function, that he used them to exercise control to an extent
which sometimes reduced his fleet cruisers below the limit of bare
necessity. The result on a memorable occasion was the escape of the enemy's
battle-fleet, but the further result is equally important. It was that the
escape of that fleet did not deprive him of the control which he was
charged to maintain. His judgment may have been at fault, but the
strategical distribution of his force was consistent throughout the whole
period of his Mediterranean command. Judged by his record, no man ever
grasped more clearly than Nelson that the object of naval warfare was to
control communications, and if he found that he had not a sufficient number
of cruisers to exercise that control and to furnish eyes for his
battle-fleet as well, it was the battle-fleet that was made to suffer, and
surely this is at least the logical view. Had the French been ready to risk
settling the question of the control in a fleet action, it would have been
different. He would then have been right to sacrifice the exercise of
control for the time in order to make sure that the action should take
place and end decisively in his favour. But he knew they were not ready to
take such a risk, and he refused to permit a purely defensive attitude on
the part of the enemy to delude him from the special function with which he
had been charged.
If the object of naval warfare is to control communications, then the
fundamental requirement is the means of exercising that control. Logically,
therefore, if the enemy holds back from battle decision, we must relegate
the battle-fleet to a secondary position, for cruisers are the means of
exercising control; the battle-fleet is but the means of preventing their
being interfered with in their work. Put it to the test of actual practice.
In no case can we exercise control by battleships alone. Their
specialisation has rendered them unfit for the work, and has made them too
costly ever to be numerous enough. Even, therefore, if our enemy had no
battle-fleet we could not make control effective with battleships alone. We
should still require cruisers specialised for the work and in sufficient
numbers to cover the necessary ground. But the converse is not true. We
could exercise control with cruisers alone if the enemy had no battle-fleet
to interfere with them.
If, then, we seek a formula that will express the practical results of our
theory, it would take some such shape as this. On cruisers depends our
exercise of control; on the battle-fleet depends the security of control.
That is the logical sequence of ideas, and it shows us that the current
maxim is really the conclusion of a logical argument in which the initial
steps must not be ignored. The maxim that the command of the sea depends on
the battle-fleet is then perfectly sound so long as it is taken to include
all the other facts on which it hangs. The true function of the
battle-fleet is to protect cruisers and flotilla at their special work. The
best means of doing this is of course to destroy the enemy's power of
interference. The doctrine of destroying the enemy's armed forces as the
paramount object here reasserts itself, and reasserts itself so strongly as
to permit for most practical purposes the rough generalisation that the
command depends upon the battle-fleet.
Of what practical use then, it may be asked, is all this hairsplitting? Why
not leave untainted the conviction that our first and foremost business is
to crush the enemy's battle-fleet, and that to this end our whole effort
should be concentrated? The answer is to point to Nelson's dilemma. It was
a dilemma which, in the golden age of naval warfare, every admiral at sea
had had to solve for himself, and it was always one of the most difficult
details of every naval war plan. If we seek to ensure the effective action
of the battle-fleet by giving it a large proportion of cruisers, by so much
do we weaken the actual and continuous exercise of control. If we seek to
make that control effective by devoting to the service a large proportion
of cruisers, by so much do we prejudice our chance of getting contact with
and defeating the enemy's battle-fleet, which is the only means of
perfecting control.
The correct solution of the dilemma will of course depend upon the
conditions of each case--mainly upon the relative strength and activity of
the hostile battle-fleet and our enemy's probable intentions. But no matter
how completely we have tabulated all the relevant facts, we can never hope
to come to a sound conclusion upon them without a just appreciation of all
the elements which go to give command, and without the power of gauging
their relative importance. This, and this alone, will ultimately settle the
vital question of what proportion of our cruiser force it is right to
devote to the battle-fleet.
If the doctrine of cruiser control be correct, then every cruiser attached
to the battle-fleet is one withdrawn from its true function. Such
withdrawals are inevitable. A squadron of battleships is an imperfect
organism unable to do its work without cruiser assistance, and since the
performance of its work is essential to cruiser freedom, some cruisers must
be sacrificed. But in what proportion? If we confine ourselves to the view
that command depends on the battle-fleet, then we shall attach to it such a
number as its commander may deem necessary to make contact with the enemy
absolutely certain and to surround himself with an impenetrable screen. If
we knew the enemy was as anxious for a decision as ourselves, such a course
might be justified. But the normal condition is that if we desire a
decision it is because we have definite hopes of success, and consequently
the enemy will probably seek to avoid one on our terms. In practice this
means that if we have perfected our arrangements for the destruction of his
main fleet he will refuse to expose it till he sees a more favourable
opportunity. And what will be the result? He remains on the defensive, and
theoretically all the ensuing period of inaction tends to fall into his
scale. Without stirring from port his fleet is doing its work. The more
closely he induces us to concentrate our cruiser force in face of his
battle-fleet, the more he frees the sea for the circulation of his own
trade, and the more he exposes ours to cruiser raids.
Experience, then, and theory alike dictate that as a general principle
cruisers should be regarded as primarily concerned with the active
occupation of communications, and that withdrawals for fleet purposes
should be reduced to the furthest margin of reasonable risk. What that
margin should be can only be decided on the circumstances of each case as
it arises, and by the personal characteristics of the officers who are
responsible. Nelson's practice was to reduce fleet cruisers lower than
perhaps any other commander. So small indeed was the margin of efficiency
he left, that in the campaign already cited, when his judgment was ripest,
one stroke of ill-luck--a chance betrayal of his position by a
neutral--availed to deprive him of the decision he sought, and to let the
enemy's fleet escape.
We arrive, then, at this general conclusion. The object of naval warfare is
to control maritime communications. In order to exercise that control
effectively we must have a numerous class of vessels specially adapted for
pursuit. But their power of exercising control is in proportion to our
degree of command, that is, to our power of preventing their operations
being interfered with by the enemy. Their own power of resistance is in
inverse proportion to their power of exercising control; that is to say,
the more numerous and better adapted they are for preying on commerce and
transports, the weaker will be their individual fighting power. We cannot
give them as a whole the power of resisting disturbance without at the same
time reducing their power of exercising control. The accepted solution of
the difficulty during the great period of Anson's school was to provide
them with a covering force of battle units specially adapted for fighting.
But here arises a correlative difficulty. In so far as we give our battle
units fighting power we deny them scouting power, and scouting is essential
to their effective operation. The battle-fleet must have eyes. Now, vessels
adapted for control of communications are also well adapted for "eyes." It
becomes the practice, therefore, to withdraw from control operations a
sufficient number of units to enable the battle-fleet to cover effectively
the operations of those that remain.
Such were the broad principles on which the inevitable dilemma always had
to be solved, and on which Anson's organisation was based. They flow
naturally from the communication theory of maritime war, and it was this
theory which then dominated naval thought, as is apparent from the
technical use of such phrases as "lines of passage and communication." The
war plans of the great strategists from Anson and Barham can always be
resolved into these simple elements, and where we find the Admiralty grip
of them loosened, we have the confusion and quite unnecessary failures of
the War of American Independence. In that mismanaged contest the cardinal
mistake was that we suffered the enemy's battle-fleets to get upon and
occupy the vital lines of "passage and communication" without first
bringing them to action, an error partly due to the unreadiness of a weak
administration, and partly to an insufficient allocation of cruisers to
secure contact at the right places.
So far, then, the principles on which our naval supremacy was built up are
clear. For the enemies with whom we had to deal Anson's system was
admirably conceived. Both Spain and France held the communication theory so
strongly, that they were content to count as success the power of
continually disturbing our control without any real attempt to secure it
for themselves. To defeat such a policy Anson's constitution and the
strategy it connoted were thoroughly well adapted and easy to work. But it
by no means follows that his doctrine is the last word. Even in his own
time complications had begun to develop which tended to confuse the
precision of his system. By the culminating year of Trafalgar there were
indications that it was getting worn out, while the new methods and
material used by the Americans in 1812 made a serious rent in it. The
disturbances then inaugurated have continued to develop, and it is
necessary to consider how seriously they have confused the problem of fleet
constitution.
Firstly, there is the general recognition, always patent to ourselves, that
by far the most drastic, economical, and effective way of securing control
is to destroy the enemy's means of interfering with it. In our own service
this "overthrow" idea always tended to assert itself so strongly, that
occasionally the means became for a time more important than the end; that
is to say, circumstances were such that on occasions it was considered
advisable to sacrifice the exercise of control for a time in order quickly
and permanently to deprive the enemy of all means of interference. When
there was reasonable hope of the enemy risking a decision this
consideration tended to override all others; but when, as in Nelson's case
in the Mediterranean, the hope was small, the exercise of control tended to
take the paramount place.
The second complexity arose from the fact that however strong might be our
battleship cover, it is impossible for it absolutely to secure cruiser
control from disturbance by sporadic attack. Isolated heavy ships, taking
advantage of the chances of the sea, could elude even the strictest
blockade, and one such ship, if she succeeded in getting upon a line of
communication, might paralyse the operations of a number of weaker units.
They must either run or concentrate, and in either case the control was
broken. If it were a squadron of heavy ships that caused the disturbance,
the practice was to detach against it a division of the covering
battle-fleet. But it was obviously highly inconvenient and contrary to the
whole idea on which the constitution of the fleet was based to allow every
slight danger to cruiser control to loosen the cohesion of the main fleet.
It was necessary, then, to give cruiser lines some power of resistance.
This necessity once admitted, there seemed no point at which you could stop
increasing the fighting power of your cruisers, and sooner or later, unless
some means of checking the process were found, the distinction between
cruisers and battleships would practically disappear. Such a means was
found in what may be called the "Intermediate" ship. Frigates did indeed
continue to increase in size and fighting power throughout the remainder of
the sailing era, but it was not only in this manner that the power of
resistance was gained. The evil results of the movement were checked by the
introduction of a supporting ship, midway between frigates and true
ships-of-the-line. Sometimes classed as a battleship, and taking her place
in the line, the 50-gun ship came to be essentially a type for stiffening
cruiser squadrons. They most commonly appear as the flagships of cruiser
commodores, or stationed in terminal waters or at focal points where
sporadic raids were likely to fall and be most destructive. The strategical
effect of the presence of such a vessel in a cruiser line was to give the
whole line in some degree the strength of the intermediate ship; for any
hostile cruiser endeavouring to disturb the line was liable to have to deal
with the supporting ship, while if a frigate and a 50-gun ship got together
they were a match even for a small ship-of-the-line.
In sailing days, of course, this power of the supporting ship was weak
owing to the imperfection of the means of distant communication between
ships at sea and the non-existence of such means beyond extreme range of
vision. But as wireless telegraphy develops it is not unreasonable to
expect that the strategic value of the supporting or intermediate ship will
be found greater than it ever was in sailing days, and that for dealing
with sporadic disturbance the tendency will be for a cruiser line to
approximate more and more in power of resistance to that of its strongest
unit.
For fleet service a cruiser's power of resistance was hardly less valuable;
for though we speak of fleet cruisers as the eyes of the fleet, their
purpose is almost equally to blindfold the enemy. Their duty is not only to
disclose the movements of the enemy, but also to act as a screen to conceal
our own. The point was specially well marked in the blockades, where the
old 50-gun ships are almost always found with the inshore cruiser squadron,
preventing that squadron being forced by inquisitive frigates. Important as
this power of resistance in the screen was in the old days, it is tenfold
more important now, and the consequent difficulty of keeping cruisers
distinct from battleships is greater than ever. The reason for this is best
considered under the third and most serious cause of complexity.
The third cause is the acquisition by the flotilla of battle power. It is a
feature of naval warfare that is entirely new.[10] For all practical
purposes it was unknown until the full development of the mobile torpedo.
It is true that the fireship as originally conceived was regarded as having
something of the same power. During the Dutch wars--the heyday of its
vogue--its assigned power was on some occasions actually realised, as in
the burning of Lord Sandwich's flagship at the battle of Solebay, and the
destruction of the Spanish-Dutch fleet at Palermo by Duquesne. But as the
"nimbleness" of great-ships increased with the ripening of seamanship and
naval architecture, the fireship as a battle weapon became almost
negligible, while a fleet at anchor was found to be thoroughly defensible
by its own picket-boats. Towards the middle of the eighteenth century
indeed the occasions on which the fireship could be used for its special
purpose was regarded as highly exceptional, and though the type was
retained till the end of the century, its normal functions differed not at
all from those of the rest of the flotilla of which it then formed part.
[10] But not without analogous precedent. In the later Middle Ages small
craft were assigned the function in battle of trying to wedge up the
rudders of great ships or bore holes between wind and water. See Fighting
Instructions (Navy Record Society), p. 13.
Those functions, as we have seen, expressed the cruising idea in its purest
sense. It was numbers and mobility that determined flotilla types rather
than armament or capacity for sea-endurance. Their primary purpose was to
control communications in home and colonial waters against weakly armed
privateers. The type which these duties determined fitted them adequately
for the secondary purpose of inshore and despatch work with a fleet. It
was, moreover, on the ubiquity which their numbers gave them, and on their
power of dealing with unarmed or lightly armed vessels, that we relied for
our first line of defence against invasion. These latter duties were of
course exceptional, and the Navy List did not carry as a rule sufficient
numbers for the purpose. But a special value of the class was that it was
capable of rapid and almost indefinite expansion from the mercantile
marine. Anything that could carry a gun had its use, and during the period
of the Napoleonic threat the defence flotilla rose all told to considerably
over a thousand units.
Formidable and effective as was a flotilla of this type for the ends it was
designed to serve, it obviously in no way affected the security of a
battle-fleet. But so soon as the flotilla acquired battle power the whole
situation was changed, and the old principles of cruiser design and
distribution were torn to shreds. The battle-fleet became a more imperfect
organism than ever. Formerly it was only its offensive power that required
supplementing. The new condition meant that unaided it could no longer
ensure its own defence. It now required screening, not only from
observation, but also from flotilla attack. The theoretical weakness of an
arrested offensive received a practical and concrete illustration to a
degree that war had scarcely ever known. Our most dearly cherished
strategical traditions were shaken to the bottom. The "proper place" for
our battle-fleet had always been "on the enemy's coasts," and now that was
precisely where the enemy would be best pleased to see it. What was to be
done? So splendid a tradition could not lightly be laid aside, but the
attempt to preserve it involved us still deeper in heresy. The vital, most
difficult, and most absorbing problem has become not how to increase the
power of a battle-fleet for attack, which is a comparatively simple matter,
but how to defend it. As the offensive power of the flotilla developed, the
problem pressed with an almost bewildering intensity. With every increase
in the speed and sea-keeping power of torpedo craft, the problem of the
screen grew more exacting. To keep the hostile flotilla out of night range
the screen must be flung out wider and wider, and this meant more and more
cruisers withdrawn from their primary function. And not only this. The
screen must not only be far flung, but it must be made as far as possible
impenetrable. In other words, its own power of resistance must be increased
all along the line. Whole squadrons of armoured cruisers had to be attached
to battle-fleets to support the weaker members of the screen. The crying
need for this type of ship set up a rapid movement for increasing their
fighting power, and with it fell with equal rapidity the economic
possibility of giving the cruiser class its essential attribute of numbers.
As an inevitable result we find ourselves involved in an effort to restore
to the flotilla some of its old cruiser capacity, by endowing it with gun
armament, higher sea-keeping power, and facilities for distant
communication, all at the cost of specialisation and of greater economic
strain. Still judged by past experience, some means of increasing numbers
in the cruising types is essential, nor is it clear how it is possible to
secure that essential in the ranks of the true cruiser. No point has been
found at which it was possible to stop the tendency of this class of vessel
to increase in size and cost, or to recall it to the strategical position
it used to occupy. So insecure is the battle-squadron, so imperfect as a
self-contained weapon has it become, that its need has overridden the old
order of things, and the primary function of the cruising ship inclines to
be no longer the exercise of control under cover of the battle-fleet. The
battle-fleet now demands protection by the cruising ship, and what the
battle-fleet needs is held to be the first necessity.
Judged by the old naval practice, it is an anomalous position to have
reached. But the whole naval art has suffered a revolution beyond all
previous experience, and it is possible the old practice is no longer a
safe guide. Driven by the same necessities, every naval Power is following
the same course. It may be right, it may be wrong; no one at least but the
ignorant or hasty will venture to pass categorical judgment. The best we
can do is to endeavour to realise the situation to which, in spite of all
misgivings, we have been forced, and to determine its relations to the
developments of the past.
It is undoubtedly a difficult task. As we have seen, there have prevailed
in the constitution of fleets at various times several methods of
expressing the necessities of naval war. The present system differs from
them all. On the one hand, we have the fact that the latest developments of
cruiser power have finally obliterated all logical distinction between
cruisers and battleships, and we thus find ourselves hand in hand with the
fleet constitution of the old Dutch wars. On the other, however, we have
armoured cruisers organised in squadrons and attached to battle-fleets not
only for strategical purposes, but also with as yet undeveloped tactical
functions in battle. Here we come close to the latest development of the
sailing era, when "Advanced" or "Light" squadrons began to appear in the
organisation of battle-fleets.
The system arose towards the end of the eighteenth century in the
Mediterranean, where the conditions of control called for so wide a
dispersal of cruisers and so great a number of them, that it was almost
imperative for a battle-squadron in that sea to do much of its own
scouting. It was certainly for this purpose that the fastest and lightest
ships-of-the-line were formed into a separate unit, and the first
designation it received was that of "Observation Squadron." It remained for
Nelson to endeavour to endow it with a tactical function, but his idea was
never realised either by himself or any of his successors.
Side by side with this new element in the organisation of a battle-fleet,
which perhaps is best designated as a "Light Division," we have another
significant fact. Not only was it not always composed entirely of
ships-of-the-line, especially in the French service, but in 1805, the year
of the full development, we have Sir Richard Strachan using the heavy
frigates attached to his battle-squadron as a "Light Division," and giving
them a definite tactical function. The collapse of the French Navy put a
stop to further developments of either idea. Whither they would have led we
cannot tell. But it is impossible to shut our eyes to the indication of a
growing tendency towards the system that exists at present. It is difficult
at least to ignore the fact that both Nelson and Strachan in that
culminating year found the actuality of war calling for something for which
there was then no provision in the constitution of the fleet, but which it
does contain to-day. What Nelson felt for was a battleship of cruiser
speed. What Strachan desired was a cruiser fit to take a tactical part in a
fleet action. We have them both, but with what result? Anson's
specialisation of types has almost disappeared, and our present fleet
constitution is scarcely to be distinguished from that of the seventeenth
century. We retain the three-fold nomenclature, but the system itself has
really gone. Battleships grade into armoured cruisers, armoured cruisers
into protected cruisers. We can scarcely detect any real distinction except
a twofold one between vessels whose primary armament is the gun and vessels
whose primary armament is the torpedo. But even here the existence of a
type of cruiser designed to act with flotillas blurs the outline, while, as
we have seen, the larger units of the flotilla are grading up to cruiser
level.
We are thus face to face with a situation which has its closest counterpart
in the structureless fleets of the seventeenth century. That naval thought
should have so nearly retraced its steps in the course of two centuries is
curious enough, but it is still more striking when we consider how widely
the underlying causes differ in each case. The pressure which has forced
the present situation is due most obviously to two causes. One is the
excessive development of the "intermediate" ship originally devised for
purposes of commerce protection, and dictated by a menace which the
experience of the American War had taught us to respect. The other is the
introduction of the torpedo, and the consequent vulnerability of
battle-squadrons that are not securely screened. Nothing of the kind had
any influence on the fleet constitution of the seventeenth century. But if
we seek deeper, there is a less obvious consideration which for what it is
worth is too striking to be ignored.
It has been suggested above that the constitution of fleets appears to have
some more or less recognisable relation to the prevalent theory of war.
Now, amongst all our uncertainty we can assert with confidence that the
theory which holds the field at the present day bears the closest possible
resemblance to that which dominated the soldier-admirals of the Dutch war.
It was the "Overthrow" theory, the firm faith in the decisive action as the
key of all strategical problems. They carried it to sea with them from the
battlefields of the New Model Army, and the Dutch met them squarely. In the
first war at least their commerce had to give place to the exigencies of
throwing into the battle everything that could affect the issue. It is not
of course pretended that this attitude was dictated by any clearly
conceived theory of absolute war. It was due rather to the fact that, owing
to the relative geographical conditions, all attempts to guard trade
communications were useless without the command of the home waters in the
North Sea, and the truth received a clinching moral emphasis from the
British claim to the actual dominion of the Narrow Seas. It was, in fact, a
war which resembled rather the continental conditions of territorial
conquest than the naval procedure that characterised our rivalry with
France.
Is it then possible, however much we may resist the conclusion in loyalty
to the eighteenth-century tradition, that the rise of a new naval Power in
the room of Holland must bring us back to the drastic, if crude, methods of
the Dutch wars, and force us to tread under foot the nicer ingenuity of
Anson's system? Is it this which has tempted us to mistrust any type of
vessel which cannot be flung into the battle? The recurrence of a
formidable rival in the North Sea was certainly not the first cause of the
reaction. It began before that menace arose. Still it has undoubtedly
forced the pace, and even if it be not a cause, it may well be a
justification.

CHAPTER THREE
* * * * *
THEORY OF THE METHOD--
CONCENTRATION AND DISPERSAL OF FORCE
* * * * *
From the point of view of the method by which its ends are obtained,
strategy is often described as the art of assembling the utmost force at
the right time and place; and this method is called "Concentration."
At first sight the term seems simple and expressive enough, but on analysis
it will be found to include several distinct ideas, to all of which the
term is applied indifferently. The result is a source of some confusion,
even to the most lucid writers. "The word concentration," says one of the
most recent of them, "evokes the idea of a grouping of forces. We believe,
in fact, that we cannot make war without grouping ships into squadrons and
squadrons into fleets."[11] Here in one sentence the word hovers between
the formation of fleets and their strategical distribution. Similar
looseness will embarrass the student at every turn. At one time he will
find the word used to express the antithesis of division or dispersal of
force; at another, to express strategic deployment, which implies division
to a greater or less extent. He will find it used of the process of
assembling a force, as well as of the state of a force when the process is
complete. The truth is that the term, which is one of the most common and
most necessary in strategical discussion, has never acquired a very precise
meaning, and this lack of precision is one of the commonest causes of
conflicting opinion and questionable judgments. No strategical term indeed
calls more urgently for a clear determination of the ideas for which it
stands.
[11] Daveluy, _L'Esprit de la Guerre Navale_, vol. i, p. 27, note.
Military phraseology, from which the word is taken, employs "concentration"
in three senses. It is used for assembling the units of an army after they
have been mobilised. In this sense, concentration is mainly an
administrative process; logically, it means the complement of the process
of mobilisation, whereby the army realises its war organisation and becomes
ready to take the field. In a second sense it is used for the process of
moving the army when formed, or in process of formation, to the localities
from which operations can best begin. This is a true strategical stage, and
it culminates in what is known as strategic deployment. Finally, it is used
for the ultimate stage when the army so deployed is closed up upon a
definite line of operations in immediate readiness for tactical
deployment--gathered up, that is, to deal a concentrated blow.
Well as this terminology appears to serve on land, where the processes tend
to overlap, something more exact is required if we try to extend it to the
sea. Such extension magnifies the error at every step, and clear thinking
becomes difficult. Even if we set aside the first meaning, that is, the
final stage of mobilisation, we have still to deal with the two others
which, in a great measure, are mutually contradictory. The essential
distinction of strategic deployment, which contemplates dispersal with a
view to a choice of combinations, is flexibility and free movement. The
characteristic of an army massed for a blow is rigidity and restricted
mobility. In the one sense of concentration we contemplate a disposal of
force which will conceal our intention from the enemy and will permit us to
adapt our movements to the plan of operations he develops. In the other,
strategic concealment is at an end. We have made our choice, and are
committed to a definite operation. Clearly, then, if we would apply the
principles of land concentration to naval warfare it is desirable to settle
which of the two phases of an operation we mean by the term.
Which meaning, then, is most closely connected with the ordinary use of the
word? The dictionaries define concentration as "the state of being brought
to a common point or centre," and this coincides very exactly with the
stage of a war plan which intervenes between the completion of mobilisation
and the final massing or deployment for battle. It is an incomplete and
continuing act. Its ultimate consequence is the mass. It is a method of
securing mass at the right time and place. As we have seen, the essence of
the state of strategic deployment to which it leads is flexibility. In war
the choice of time and place will always be influenced by the enemy's
dispositions and movements, or by our desire to deal him an unexpected
blow. The merit of concentration, then, in this sense, is its power of
permitting us to form our mass in time at one of the greatest number of
different points where mass may be required.
It is for this stage that the more recent text-books incline to specialise
concentration--qualifying it as "strategic concentration." But even that
term scarcely meets the case, for the succeeding process of gathering up
the army into a position for tactical deployment is also a strategical
concentration. Some further specialisation is required. The analytical
difference between the two processes is that the first is an operation of
major strategy and the other of minor, and if they are to be fully
expressed, we have to weight ourselves with the terms "major and minor
strategic concentration."
Such cumbrous terminology is too forbidding to use. It serves only to mark
that the middle stage differs logically from the third as much as it does
from the first. In practice it comes to this. If we are going to use
concentration in its natural sense, we must regard it as something that
comes after complete mobilisation and stops short of the formation of mass.
In naval warfare at least this distinction between concentration and mass
is essential to clear appreciation. It leads us to conclusions that are of
the first importance. For instance, when once the mass is formed,
concealment and flexibility are at an end. The further, therefore, from the
formation of the ultimate mass we can stop the process of concentration the
better designed it will be. The less we are committed to any particular
mass, and the less we indicate what and where our mass is to be, the more
formidable our concentration. To concentration, therefore, the idea of
division is as essential as the idea of connection. It is this view of the
process which, at least for naval warfare, a weighty critical authority has
most strongly emphasised. "Such," he says, "is concentration reasonably
understood--not huddled together like a drove of sheep, but distributed
with a regard to a common purpose, and linked together by the effectual
energy of a single will."[12] Vessels in a state of concentration he
compares to a fan that opens and shuts. In this view concentration connotes
not a homogeneous body, but a compound organism controlled from a common
centre, and elastic enough to permit it to cover a wide field without
sacrificing the mutual support of its parts.
[12] Mahan, _War of 1812_, i, 316.
If, then, we exclude the meaning of mere assembling and the meaning of the
mass, we have left a signification which expresses coherent disposal about
a strategical centre, and this it will be seen gives for naval warfare just
the working definition that we want as the counterpart of strategic
deployment on land. The object of a naval concentration like that of
strategic deployment will be to cover the widest possible area, and to
preserve at the same time elastic cohesion, so as to secure rapid
condensations of any two or more of the parts of the organism, and in any
part of the area to be covered, at the will of the controlling mind; and
above all, a sure and rapid condensation of the whole at the strategical
centre.
Concentration of this nature, moreover, will be the expression of a war
plan which, while solidly based on an ultimate central mass, still
preserves the faculty of delivering or meeting minor attacks in any
direction. It will permit us to exercise control of the sea while we await
and work for the opportunity of a decision which shall permanently secure
control, and it will permit this without prejudicing our ability of
bringing the utmost force to bear when the moment for the decision arrives.
Concentration, in fact, implies a continual conflict between cohesion and
reach, and for practical purposes it is the right adjustment of those two
tensions--ever shifting in force--which constitutes the greater part of
practical strategy.
In naval warfare this concentration stage has a peculiar significance in
the development of a campaign, and at sea it is more clearly detached than
ashore. Owing to the vast size of modern armies, and the restricted nature
of their lines of movement, no less than their lower intrinsic mobility as
compared with fleets, the processes of assembly, concentration, and forming
the battle mass tend to grade into one another without any demarcation of
practical value. An army frequently reaches the stage of strategic
deployment direct from the mobilisation bases of its units, and on famous
occasions its only real concentration has taken place on the battlefield.
In Continental warfare, then, there is less difficulty in using the term to
cover all three processes. Their tendency is always to overlap. But at sea,
where communications are free and unrestricted by obstacles, and where
mobility is high, they are susceptible of sharper differentiation. The
normal course is for a fleet to assemble at a naval port; thence by a
distinct movement it proceeds to the strategical centre and reaches out in
divisions as required. The concentration about that centre may be very far
from a mass, and the final formation of the mass will bear no resemblance
to either of the previous movements, and will be quite distinct.
But free as a fleet is from the special fetters of an army, there always
exist at sea peculiar conditions of friction which clog its freedom of
disposition. One source of this friction is commerce protection. However
much our war plan may press for close concentration, the need of commerce
protection will always be calling for dispersal. The other source is the
peculiar freedom and secrecy of movements at sea. As the sea knows no roads
to limit or indicate our own lines of operation, so it tells little about
those of the enemy. The most distant and widely dispersed points must be
kept in view as possible objectives of the enemy. When we add to this that
two or more fleets can act in conjunction from widely separated bases with
far greater certainty than is possible for armies, it is obvious that the
variety of combinations is much higher at sea than on land, and variety of
combination is in constant opposition to the central mass.
It follows that so long as the enemy's fleet is divided, and thereby
retains various possibilities of either concentrated or sporadic action,
our distribution will be dictated by the need of being able to deal with a
variety of combinations and to protect a variety of objectives. Our
concentrations must therefore be kept as open and flexible as possible.
History accordingly shows us that the riper and fresher our experience and
the surer our grip of war, the looser were our concentrations. The idea of
massing, as a virtue in itself, is bred in peace and not in war. It
indicates the debilitating idea that in war we must seek rather to avoid
than to inflict defeat. True, advocates of the mass entrench themselves in
the plausible conception that their aim is to inflict crushing defeats. But
this too is an idea of peace. War has proved to the hilt that victories
have not only to be won, but worked for. They must be worked for by bold
strategical combinations, which as a rule entail at least apparent
dispersal. They can only be achieved by taking risks, and the greatest and
most effective of these is division.
The effect of prolonged peace has been to make "concentration" a kind of
shibboleth, so that the division of a fleet tends almost to be regarded as
a sure mark of bad leadership. Critics have come to lose sight of the old
war experience, that without division no strategical combinations are
possible. In truth they must be founded on division. Division is bad only
when it is pushed beyond the limits of well-knit deployment. It is
theoretically wrong to place a section of the fleet in such a position that
it may be prevented from falling back on its strategical centre when it is
encountered by a superior force. Such retreats of course can never be made
certain; they will always depend in some measure on the skill and resource
of the opposing commanders, and on the chances of weather: but risks must
be taken. If we risk nothing, we shall seldom perform anything. The great
leader is the man who can measure rightly to what breadth of deployment he
can stretch his concentration. This power of bold and sure adjustment
between cohesion and reach is indeed a supreme test of that judgment which
in the conduct of war takes the place of strategical theory.
In British naval history examples of faulty division are hard to find. The
case most commonly cited is an early one. It occurred in 1666 during the
second Dutch war. Monk and Rupert were in command of the main fleet, which
from its mobilisation bases in the Thames and at Spithead had concentrated
in the Downs. There they were awaiting De Ruyter's putting to sea in a
position from which they could deal with him whether his object was an
attack on the Thames or to join hands with the French. In this position a
rumour reached them that the Toulon squadron was on its way to the Channel
to co-operate with the Dutch. Upon this false intelligence the fleet was
divided, and Rupert went back to Portsmouth to cover that position in case
it might be the French objective. De Ruyter at once put to sea with a fleet
greatly superior to Monk's division. Monk, however, taking advantage of
thick weather that had supervened, surprised him at anchor, and believing
he had a sufficient tactical advantage attacked him impetuously. Meanwhile
the real situation became known. There was no French fleet, and Rupert was
recalled. He succeeded in rejoining Monk after his action with De Ruyter
had lasted three days. In the course of it Monk had been very severely
handled and forced to retreat to the Thames, and it was generally believed
that it was only the belated arrival of Rupert that saved us from a real
disaster.
The strategy in this case is usually condemned out of hand and made to bear
the entire blame of the reverse. Monk, who as a soldier had proved himself
one of the finest strategists of the time, is held to have blundered from
sheer ignorance of elementary principles. It is assumed that he should have
kept his fleet massed; but his critics fail to observe that at least in the
opinion of the time this would not have met the case. Had he kept the whole
to deal with De Ruyter, it is probable that De Ruyter would not have put to
sea, and it is certain Portsmouth and the Isle of Wight would have lain
open to the French had they come. If he had moved his mass to deal with the
French, he would have exposed the Thames to De Ruyter. It was a situation
that could not be solved by a simple application of what the French call
the _masse centrale_. The only way to secure both places from attack was to
divide the fleet, just as in 1801 Nelson in the same theatre was compelled
to divide his defence force. In neither case was division a fault, because
it was a necessity. The fault in Monk's and Rupert's case was that they
extended their reach with no proper provision to preserve cohesion. Close
cruiser connection should have been maintained between the two divisions,
and Monk should not have engaged deeply till he felt Rupert at his elbow.
This we are told was the opinion of most of his flag-officers. They held
that he should not have fought when he did. His correct course, on
Kempenfelt's principle, would have been to hang on De Ruyter so as to
prevent his doing anything, and to have slowly fallen back, drawing the
Dutch after him till his loosened concentration was closed up again. If De
Ruyter had refused to follow him through the Straits, there would have been
plenty of time to mass the fleet. If De Ruyter had followed, he could have
been fought in a position from which there would have been no escape. The
fault, in fact, was not strategical, but rather one of tactical judgment.
Monk over-estimated the advantage of his surprise and the relative fighting
values of the two fleets, and believed he saw his way to victory
single-handed. The danger of division is being surprised and forced to
fight in inferiority. This was not Monk's case. He was not surprised, and
he could easily have avoided action had he so desired. To judge such a case
simply by using concentration as a touchstone can only tend to set up such
questionable habits of thought as have condemned the more famous division
which occurred in the crisis of the campaign of 1805, and with which we
must deal later.
Apart from the general danger of using either words or maxims in this way,
it is obviously specially unwise in the case of concentration and division.
The current rule is that it is bad to divide unless you have a great
superiority; yet there have been numerous occasions when, being at war with
an inferior enemy, we have found our chief embarrassment in the fact that
he kept his fleet divided, and was able thereby to set up something like a
deadlock. The main object of our naval operations would then be to break it
down. To force an inferior enemy to concentrate is indeed the almost
necessary preliminary to securing one of those crushing victories at which
we must always aim, but which so seldom are obtained. It is by forcing the
enemy to attempt to concentrate that we get our opportunity by sagacious
dispersal of crushing his divisions in detail. It is by inducing him to
mass that we simplify our problem and compel him to choose between leaving
to us the exercise of command and putting it to the decision of a great
action.
Advocates of close concentration will reply that that is true enough. We do
often seek to force our enemy to concentrate, but that does not show that
concentration is sometimes a disadvantage, for we ourselves must
concentrate closely to force a similar concentration on the enemy. The
maxim, indeed, has become current that concentration begets concentration,
but it is not too much to say that it is a maxim which history flatly
contradicts. If the enemy is willing to hazard all on a battle, it is true.
But if we are too superior, or our concentration too well arranged for him
to hope for victory, then our concentration has almost always had the
effect of forcing him to disperse for sporadic action. So certain was this
result, that in our old wars, in which we were usually superior, we always
adopted the loosest possible concentrations in order to prevent sporadic
action. True, the tendency of the French to adopt this mode of warfare is
usually set down to some constitutional ineptitude that is outside
strategical theory, but this view is due rather to the irritation which the
method caused us, than to sober reasoning. For a comparatively weak
belligerent sporadic action was better than nothing, and the only other
alternative was for him to play into our hands by hazarding the decision
which it was our paramount interest to obtain. Sporadic action alone could
never give our enemy command of the sea, but it could do us injury and
embarrass our plans, and there was always hope it might so much loosen our
concentration as to give him a fair chance of obtaining a series of
successful minor decisions.
Take, now, the leading case of 1805. In that campaign our distribution was
very wide, and was based on several concentrations. The first had its
centre in the Downs, and extended not only athwart the invading army's line
of passage, but also over the whole North Sea, so as to prevent
interference with our trade or our system of coast defence either from the
Dutch in the Texel or from French squadrons arriving north-about. The
second, which was known as the Western Squadron, had its centre off Ushant,
and was spread over the whole Bay of Biscay by means of advanced squadrons
before Ferrol and Rochefort. With a further squadron off the coast of
Ireland, it was able also to reach far out into the Atlantic in order to
receive our trade. It kept guard, in fact, not only over the French naval
ports, but over the approaches to the Channel, where were the home
terminals of the great southern and western trade-routes. A third
concentration was in the Mediterranean, whose centre under Nelson was at
Sardinia. It had outlying sub-centres at Malta and Gibraltar, and covered
the whole ground from Cape St. Vincent outside the Straits to Toulon,
Trieste, and the Dardanelles. When war broke out with Spain in 1804, it was
considered advisable to divide this command, and Spanish waters outside the
Straits were held by a fourth concentration, whose centre was off Cadiz,
and whose northern limit was Cape Finisterre, where it joined the Ushant
concentration. For reasons which were personal rather than strategical this
arrangement was not continued long, nor indeed after a few months was there
the same need for it, for the Toulon squadron had changed its base to
Cadiz. By this comprehensive system the whole of the European seas were
controlled both for military and trade purposes. In the distant terminal
areas, like the East and West Indies, there were nucleus concentrations
with the necessary connective machinery permanently established, and to
render them effective, provision was made by which the various European
squadrons could throw off detachments to bring up their force to any
strength which the movements of the enemy might render necessary.
Wide as was this distribution, and great as its reach, a high degree of
cohesion was maintained not only between the parts of each concentration,
but between the several concentrations themselves. By means of a minor
cruiser centre at the Channel Islands, the Downs and Ushant concentrations
could rapidly cohere. Similarly the Cadiz concentration was linked up with
that of Ushant at Finisterre, and but for personal friction and repulsion,
the cohesion between the Mediterranean and Cadiz concentrations would have
been equally strong. Finally, there was a masterly provision made for all
the concentrations to condense into one great mass at the crucial point off
Ushant before by any calculable chance a hostile mass could gather there.
For Napoleon's best admirals, "who knew the craft of the sea," the British
fleet thus disposed was in a state of concentration that nothing but a
stroke of luck beyond the limit of sober calculation could break. Decrès
and Bruix had no doubt of it, and the knowledge overpowered Villeneuve when
the crisis came. After he had carried the concentration which Napoleon had
planned so far as to have united three divisions in Ferrol, he knew that
the outlying sections of our Western Squadron had disappeared from before
Ferrol and Rochefort. In his eyes, as well as those of the British
Admiralty, this squadron, in spite of its dispersal in the Bay of Biscay,
had always been in a state of concentration. It was not this which caused
his heart to fail. It was the news that Nelson had reappeared at Gibraltar,
and had been seen steering northward. It meant for him that the whole of
his enemy's European fleet was in a state of concentration. "Their
concentration of force," he afterwards wrote, "was at the moment more
serious than in any previous disposition, and such that they were in a
position to meet in superiority the combined forces of Brest and Ferrol,"
and for that reason, he explained, he had given up the game as lost. But to
Napoleon's unpractised eye it was impossible to see what it was he had to
deal with. Measuring the elasticity of the British naval distribution by
the comparatively cumbrous and restricted mobility of armies, he saw it as
a rash and unwarlike dispersal. Its looseness seemed to indicate so great a
tenderness for the distant objectives that lay open to his scattered
squadrons, that he believed by a show of sporadic action he could further
disperse our fleet, and then by a close concentration crush the essential
part in detail. It was a clear case of the enemy's dispersal forcing us to
adopt the loosest concentration, and of our comparative dispersal tempting
the enemy to concentrate and hazard a decision. It cannot be said we forced
the fatal move upon him intentionally. It was rather the operation of
strategical law set in motion by our bold distribution. We were determined
that his threat of invasion, formidable as it was, should not force upon us
so close a concentration as to leave our widespread interests open to his
attack. Neither can it be said that our first aim was to prevent his
attempting to concentrate. Every one of his naval ports was watched by a
squadron, but it was recognised that this would not prevent concentration.
The escape of one division might well break the chain. But that
consideration made no difference. The distribution of our squadrons before
his naval ports was essential for preventing sporadic action. Their
distribution was dictated sufficiently by the defence of commerce and of
colonial and allied territory, by our need, that is, to exercise a general
command even if we could not destroy the enemy's force.
The whole of Nelson's correspondence for this period shows that his main
object was the protection of our Mediterranean trade and of Neapolitan and
Turkish territory. When Villeneuve escaped him, his irritation was caused
not by the prospect of a French concentration, which had no anxieties for
him, for he knew counter-concentrations were provided for. It was caused
rather by his having lost the opportunity which the attempt to concentrate
had placed within his reach. He followed Villeneuve to the West Indies, not
to prevent concentration, but, firstly, to protect the local trade and
Jamaica, and secondly, in hope of another chance of dealing the blow he had
missed. Lord Barham took precisely the same view. When on news of
Villeneuve's return from the West Indies he moved out the three divisions
of the Western Squadron, that is, the Ushant concentration, to meet him, he
expressly stated, not that his object was to prevent concentration, but
that it was to deter the French from attempting sporadic action. "The
interception of the fleet in question," he wrote, "on its return to Europe
would be a greater object than any I know. It would damp all future
expeditions, and would show to Europe that it might be advisable to relax
in the blockading system occasionally for the express purpose of putting
them in our hands at a convenient opportunity."
Indeed we had no reason for preventing the enemy's concentration. It was
our best chance of solving effectually the situation we have to confront.
Our true policy was to secure permanent command by a great naval decision.
So long as the enemy remained divided, no such decision could be expected.
It was not, in fact, till he attempted his concentration, and its last
stage had been reached, that the situation was in our hands. The intricate
problem with which we had been struggling was simplified down to closing up
our own concentration to the strategical centre off Ushant. But at the last
stage the enemy could not face the formidable position we held. His
concentration was stopped. Villeneuve fell back on Cadiz, and the problem
began to assume for us something of its former intricacy. So long as we
held the mass off Ushant which our great concentration had produced, we
were safe from invasion. But that was not enough. It left the seas open to
sporadic action from Spanish ports. There were convoys from the East and
West Indies at hand, and there was our expedition in the Mediterranean in
jeopardy, and another on the point of sailing from Cork. Neither Barham at
the Admiralty nor Cornwallis in command off Ushant hesitated an hour. By a
simultaneous induction they both decided the mass must be divided. The
concentration must be opened out again, and it was done. Napoleon called
the move an _insigne betise_, but it was the move that beat him, and must
have beaten him, whatever the skill of his admirals, for the two squadrons
never lost touch. He found himself caught in a situation from which there
was nothing to hope. His fleet was neither concentrated for a decisive blow
nor spread for sporadic action. He had merely simplified his enemy's
problem. Our hold was surer than ever, and in a desperate attempt to
extricate himself he was forced to expose his fleet to the final decision
we required.
The whole campaign serves well to show what was understood by concentration
at the end of the great naval wars. To Lord Barham and the able admirals
who interpreted his plans it meant the possibility of massing at the right
time and place. It meant, in close analogy to strategic deployment on land,
the disposal of squadrons about a strategical centre from which fleets
could condense for massed action in any required direction, and upon which
they could fall back when unduly pressed. In this case the ultimate centre
was the narrows of the Channel, where Napoleon's army lay ready to cross,
but there was no massing there. So crude a distribution would have meant a
purely defensive attitude. It would have meant waiting to be struck instead
of seeking to strike, and such an attitude was arch-heresy to our old
masters of war.
So far we have only considered concentration as applied to wars in which we
have a preponderance of naval force, but the principles are at least
equally valid when a coalition places us in inferiority. The leading case
is the home campaign of 1782. It was strictly on defensive lines. Our
information was that France and Spain intended to end the war with a great
combined effort against our West Indian islands, and particularly Jamaica.
It was recognised that the way to meet the threat was to concentrate for
offensive action in the Caribbean Sea everything that was not absolutely
needed for home defence. Instead, therefore, of trying to be strong enough
to attempt the offensive in both areas, it was decided to make sure of the
area that was most critical. To do this the home fleet had to be reduced so
low relatively to what the enemy had in European waters that offence was
out of the question.
While Rodney took the offensive area, Lord Howe was given the other. His
task was to prevent the coalition obtaining such a command of home waters
as would place our trade and coasts at their mercy, and it was not likely
to prove a light one. We knew that the enemy's plan was to combine their
attack on the West Indies with an attempt to control the North Sea, and
possibly the Straits of Dover, with a Dutch squadron of twelve to fifteen
of the line, while a combined Franco-Spanish fleet of at least forty sail
would occupy the mouth of the Channel. It was also possible that these two
forces would endeavour to form a junction. In any case the object of the
joint operations would be to paralyse our trade and annoy our coasts, and
thereby force us to neglect the West Indian area and the two Spanish
objectives, Minorca and Gibraltar. All told we had only about thirty of the
line on the home station, and though a large proportion of these were
three-deckers, a good many could not be ready for sea till the summer.
Inferior as was the available force, there was no thought of a purely
passive defence. It would not meet the case. Something must be done to
interfere with the offensive operations of the allies in the West Indies
and against Gibraltar, or they would attain the object of their home
campaign. It was resolved to effect this by minor counterstrokes on their
line of communications to the utmost limit of our defensive reach. It would
mean a considerable stretch of our concentration, but we were determined to
do what we could to prevent reinforcements from reaching the West Indies
from Brest, to intercept French trade as occasion offered, and, finally, at
almost any risk to relieve Gibraltar.
In these conditions the defensive concentration was based on a central mass
or reserve at Spithead, a squadron in the Downs to watch the Texel for the
safety of the North Sea trade, and another to the westward to watch Brest
and interrupt its transatlantic communications. Kempenfelt in command of
the latter squadron had just shown what could be done by his great exploit
of capturing Guichen's convoy of military and naval stores for the West
Indies. Early in the spring he was relieved by Barrington, who sailed on
April 5th to resume the Ushant position. His instructions were not to fight
a superior enemy unless in favourable circumstances, but to retire on
Spithead. He was away three weeks, and returned with a French East India
convoy with troops and stores, and two of the ships of-the-line which
formed its escort.
Up to this time there had been no immediate sign of the great movement from
the south. The Franco-Spanish fleet which had assembled at Cadiz was
occupied ineffectually in trying to stop small reliefs reaching Gibraltar
and in covering their own homeward-bound trade. The Dutch, however, were
becoming active, and the season was approaching for our Baltic trade to
come home. Ross in the North Sea had but four of the line to watch the
Texel, and was in no position to deal with the danger. Accordingly early in
May the weight of the home concentration was thrown into the North Sea. On
the 10th Howe sailed with Barrington and the bulk of the fleet to join Ross
in the Downs, while Kempenfelt again took the Ushant position. Only about
half the Brest Squadron had gone down to join the Spaniards at Cadiz, and
he was told his first duty was to intercept the rest if it put to sea, but,
as in Barrington's instructions, if he met a superior squadron he was to
retire up Channel under the English coast and join hands with Howe. In
spite of the fact that influenza was now raging in the fleet, he succeeded
in holding the French inactive. Howe with the same difficulty to face was
equally successful. The Dutch had put to sea, but returned immediately they
knew of his movement, and cruising off the Texel, he held them there, and
kept complete command of the North Sea till our Baltic trade was safe home.
By the end of May it was done, and as our intelligence indicated that the
great movement from Cadiz was at last about to begin, Howe, to whom a
certain discretion had been left, decided it was time to shift the weight
to his other wing and close on Kempenfelt. The Government, however, seemed
to think that he ought to be able to use his position for offensive
operations against Dutch trade, but in the admiral's opinion this was to
lose hold of the design and sacrifice cohesion too much to reach. He
informed them that he had not deemed it advisable to make detachments from
his squadron against the trade, "not knowing how suddenly there might be a
call, for the greater part of it at least, to the westward." In accordance,
therefore, with his general instructions he left with Ross a strong
squadron of nine of the line, sufficient to hold in check, and even "to
take and destroy," the comparatively weak ships of the Dutch, and with the
rest returned to the westward.[13] His intention was to proceed with all
possible expedition to join Kempenfelt on the coast of France, but this,
owing to the ravages of the influenza, he was unable to do. Kempenfelt was
forced to come in, and on June 5th the junction was made at Spithead.
[13] The Dutch were believed to have sixteen of the line--one
seventy-four, seven sixty-eights, and the rest under sixty guns. In
Ross's squadron were one three-decker and two eighties.
For three weeks, so severe was the epidemic, they could not move. Then came
news that the Cadiz fleet under Langara had sailed the day Howe had reached
Spithead, and he resolved to make a dash with every ship fit to put to sea
to cut it off from Brest. He was too late. Before he could get into
position the junction between Langara and the Brest squadron was made, and
in their full force the allies had occupied the mouth of the Channel. With
the addition of the Brest ships the combined fleet numbered forty of the
line, while all Howe could muster was twenty-two, but amongst them were
seven three-deckers and three eighties, and he would soon be reinforced.
Three of Ross's smallest ships were recalled, and five others were nearly
ready, but for these Howe could not wait. The homeward-bound Jamaica convoy
was at hand, and at all hazards it must be saved.
What was to be done? So soon as he sighted the enemy he realised that a
successful action was out of the question. Early in the morning of July
12th, "being fifteen leagues S.S.E. from Scilly," Langara with thirty-six
of the line was seen to the westward. "As soon," wrote Howe, "as their
force had been ascertained, I thought proper to avoid coming to battle with
them as then circumstanced, and therefore steered to the north to pass
between Scilly and the Land's End. My purpose therein was to get to the
westward of the enemy, both for protecting the Jamaica convoy and to gain
the advantage of situation for bringing them to action which the difference
in our numbers renders desirable."
By a most brilliant effort of seamanship the dangerous movement was
effected safely that night, and it proved an entire success. Till Howe was
met with and defeated, the allies would not venture into the Channel, and
his unprecedented feat had effectually thrown them off. Assuming apparently
that he must have passed round their rear to seaward, they sought him to
the southward, and there for a month beat up and down in ineffective
search. Meanwhile Howe, sending his cruisers ahead to the convoy's
rendezvous off the south-west coast of Iceland, had taken his whole fleet
about two hundred miles west of the Skelligs to meet it. Northerly winds
prevented his reaching the right latitude in time, but it mattered little.
The convoy passed in between him and the south of Ireland, and as the enemy
had taken a cast down to Ushant, it was able to enter the Channel in safety
without sighting an enemy's sail. Ignorant of what had happened, Howe
cruised for a week practising the ships "in connected movements so
particularly necessary on the present occasion." Then with his fleet in
fine condition to carry out preventive tactics in accordance with
Kempenfelt's well-known exposition,[14] he returned to seek the enemy to
the eastward, in order to try to draw them from their station at Scilly and
open the Channel. On his way he learnt the convoy had passed in, and with
this anxiety off his mind he bore up for the Lizard, where his
reinforcements were awaiting him. There he found the Channel was free. From
lack of supplies the enemy had been forced to retire to port, and he
returned to Spithead to make preparations for the relief of Gibraltar.
While this work was going on, the North Sea squadron was again strengthened
that it might resume the blockade of the Texel and cover the arrival of the
autumn convoys from the Baltic. It was done with complete success. Not a
single ship fell into the enemy's hands, and the campaign, and indeed the
war, ended by Howe taking the mass of his force down to Gibraltar and
performing his remarkable feat of relieving it in the face of the Spanish
squadron. For the power and reach of a well-designed concentration there
can be no finer example.
[14] See post, pp. 222-24.
If, now, we seek from the above and similar examples for principles to
serve as a guide between concentration and division we shall find, firstly,
this one. The degree of division we shall require is in proportion to the
number of naval ports from which the enemy can act against our maritime
interests and to the extent of coastline along which they are spread. It is
a principle which springs from the soul of our old tradition that we must
always seek, not merely to prevent the enemy striking at our heart, but
also to strike him the moment he attempts to do anything. We must make of
his every attempt an opportunity for a counterstroke. The distribution this
aim entailed varied greatly with different enemies. In our wars with
France, and particularly when Spain and Holland were in alliance with her,
the number of the ports to be dealt with was very considerable and their
distribution very wide. In our wars with the Dutch alone, on the other
hand, the number and distribution were comparatively small, and in this
case our concentration was always close.
This measure of distribution, however, will never stand alone.
Concentration will not depend solely upon the number and position of the
enemy's naval ports. It will be modified by the extent to which the lines
of operation starting from those ports traverse our own home waters. The
reason is plain. Whatever the enemy opposed to us, and whatever the nature
of the war, we must always keep a fleet at home. In any circumstances it is
essential for the defence of our home trade terminals, and it is essential
as a central reserve from which divisions can be thrown off to reinforce
distant terminals and to seize opportunities for counterstrokes. It is "the
mainspring," as Lord Barham put it, "from which all offensive operations
must proceed." This squadron, then, being permanent and fixed as the
foundation of our whole system, it is clear that if, as in the case of the
French wars, the enemy's lines of operation do not traverse our home
waters, close concentration upon it will not serve our turn. If, on the
other hand, as in the case of the Dutch wars, the lines do traverse home
waters, a home concentration is all that is required. Our division will
then be measured by the amount of our surplus strength, and by the extent
to which we feel able to detach squadrons for offensive action against the
enemy's distant maritime interests without prejudicing our hold on the home
terminals of his lines of operation and our power of striking directly he
moves. These remarks apply, of course, to the main fleet operations. If
such an enemy has distant colonial bases from which he can annoy our trade,
minor concentrations must naturally be arranged in those areas.
Next we have to note that where the enemy's squadrons are widely
distributed in numerous bases, we cannot always simplify the problem by
leaving some of them open so as to entice him to concentrate and reduce the
number of ports to be watched. For if we do this, we leave the unwatched
squadrons free for sporadic action. Unless we are sure he intends to
concentrate with a view to a decisive action, our only means of simplifying
the situation is to watch every port closely enough to interfere
effectually with sporadic action. Then, sporadic action being denied him,
the enemy must either do nothing or concentrate.
The next principle is flexibility. Concentration should be so arranged that
any two parts may freely cohere, and that all parts may quickly condense
into a mass at any point in the area of concentration. The object of
holding back from forming the mass is to deny the enemy knowledge of our
actual distribution or its intention at any given moment, and at the same
time to ensure that it will be adjusted to meet any dangerous movement that
is open to him. Further than this our aim should be not merely to prevent
any part being overpowered by a superior force, but to regard every
detached squadron as a trap to lure the enemy to destruction. The ideal
concentration, in short, is an appearance of weakness that covers a reality
of strength.

CONDUCT OF NAVAL WAR
* * * * *
CHAPTER ONE
INTRODUCTORY
* * * * *
I. INHERENT DIFFERENCES IN THE
CONDITIONS OF WAR ON LAND AND ON SEA
Before attempting to apply the foregoing general principles in a definite
manner to the conduct of naval war, it is necessary to clear the ground of
certain obstacles to right judgment. The gradual elucidation of the theory
of war, it must be remembered, has been almost entirely the work of
soldiers, but so admirable is the work they have done, and so philosophical
the method they have adopted, that a very natural tendency has arisen to
assume that their broad-based conclusions are of universal application.
That the leading lines which they have charted are in a certain sense those
which must govern all strategy no one will deny. They are the real
pioneers, and their methods must be in the main our methods, but what we
have to remember is that the country we have to travel is radically
different from that in which they acquired their skill.
A moment's consideration will reveal how far-reaching the differences are.
Let us ask ourselves what are the main ideas around which all the military
lore turns. It may be taken broadly that the general principles are three
in number. Firstly, there is the idea of concentration of force, that is,
the idea of overthrowing the enemy's main strength by bringing to bear upon
it the utmost accumulation of weight and energy within your means;
secondly, there is the idea that strategy is mainly a question of definite
lines of communication; and thirdly, there is the idea of concentration of
effort, which means keeping a single eye on the force you wish to overthrow
without regard to ulterior objects. Now if we examine the conditions which
give these principles so firm a footing on land, we shall find that in all
three cases they differ at sea, and differ materially.
Take the first, which, in spite of all the deductions we have to make from
it in the case of limited wars, is the dominating one. The pithy maxim
which expresses its essence is that our primary objective is the enemy's
main force. In current naval literature the maxim is applied to the sea in
some such form as this: "The primary object of our battle-fleet is to seek
out and destroy that of the enemy." On the surface nothing could look
sounder, but what are the conditions which underlie the one and the other?
The practical value of the military maxim is based upon the fact that in
land warfare it is always theoretically possible to strike at your enemy's
army, that is, if you have the strength and spirit to overcome the
obstacles and face the risks. But at sea this is not so. In naval warfare
we have a far-reaching fact which is entirely unknown on land. It is simply
this--that it is possible for your enemy to remove his fleet from the board
altogether. He may withdraw it into a defended port, where it is absolutely
out of your reach without the assistance of an army. No amount of naval
force, and no amount of offensive spirit, can avail you. The result is that
in naval warfare an embarrassing dilemma tends to assert itself. If you are
in a superiority that justifies a vigorous offensive and prompts you to
seek out your enemy with a view to a decision, the chances are you will
find him in a position where you cannot touch him. Your offence is
arrested, and you find yourself in what, at least theoretically, is the
weakest general position known to war.
This was one of our earliest discoveries in strategy. It followed indeed
immediately and inevitably upon our discovery that the most drastic way of
making war was to concentrate every effort on the enemy's armed forces. In
dealing with the theory of war in general a caveat has already been entered
against the too common assumption that this method was an invention of
Napoleon's or Frederick's, or that it was a foreign importation at all. In
the view at least of our own military historians the idea was born in our
Civil Wars with Cromwell and the New Model Army. It was the conspicuous
feature that distinguished our Civil War from all previous wars of modern
times. So astonishing was its success--as foreign observers remarked--that
it was naturally applied by our soldier-admirals at sea so soon as war
broke out with the Dutch. Whatever may be the claims of the Cromwellian
soldiers to have invented for land warfare what is regarded abroad as the
chief characteristic of the Napoleonic method, it is beyond doubt that they
deserve the credit of it at sea. All three Dutch wars had a commercial
object, and yet after the first campaign the general idea never was to make
the enemy's commerce a primary objective. That place was occupied
throughout by their battle-fleets, and under Monk and Rupert at least those
objectives were pursued with a singleness of purpose and a persistent
vehemence that was entirely Napoleonic.
