CHAPTER VI

THE MORAL INFLUENCE OF UNDER-WATER WARFARE

“I think that the enthusiasm with which in some countries, the

studies and the building of submarine boats have been accompanied is

in great part due to the feeling implanted in human nature, by which

danger appears the greater in proportion as it is more mysteriously

and insidiously able to threaten the existence of its adversaries”

(Rear-Admiral BETTOLO, in “All the World’s Fighting Ships,” 1901).

It was once said that the principal value of all methods of submarine

warfare was analogous to that of the notice board which tells the

would-be burglar to “Beware of the dog.”

In the face of a warning such as this the burglar is forced to take a

rapid survey of the situation. In the first place, he cannot tell

whether there really is any dog on the premises at all, and secondly he

has no means of discovering whether the animal, if there be one, is old,

blind, or decrepit and thus worthy of being disregarded. Which is his

best plan? to take his chance and trust to luck or leave the place

severely alone and look out for some other establishment where no such

notice meets his eye?

Some burglars might take one course and some another, according to their

individual temperament, but at any rate the warning serves this purpose,

that it causes the would-be house-breaker to pause before he commits his

crime, even if it does not act as a complete deterrent.

What the notice board is to the burglar, the mine, the torpedo, or the

submarine boat is to the naval officer, and in laying his plans he must

take into consideration the possibility of being blown up by one or

other of these methods of under-water attack. “The King’s Navee” has no

lack of brave men ready to risk their lives at a moment’s notice, and a

British officer if told to accomplish any task would as soon think of

replying that there were mines, torpedo-boats, and submarines in the

path of his advance as he would of going into action in a frock coat and

a silk hat.

He will undertake his task cheerfully and instantly, and he knows he can

rely on the support of his crew, but at the same time it is impossible

both for captain and crew to disregard absolutely the unseen dangers

that may lie in their way.

Though this will not prevent a British warship from going wherever it is

bid, yet the knowledge that they may at any moment be sent to the bottom

by the explosion of a submarine mine or by the blow of a Whitehead

torpedo, must of necessity make them nervous and will very likely have a

bad influence on their powers of shooting straight. “The presence of

mines,” says a naval writer, “has a moral effect upon crews which does

not altogether improve their shooting.”

So great has been the recent improvement in the _matériel_ of

under-water warfare that we have no chance of gauging accurately its

potential effect from a moral point of view. The mines, torpedoes, and

submarines hitherto employed in naval engagements are excessively crude

when compared with their modern equivalents, and the countries which

have used them have not been those most skilled in the practice of such

weapons. There is, however, sufficient evidence both from naval wars and

also from mimic battles to show that the mine, the torpedo and the

submarine will exercise a considerable moral influence when the next

great fight on the seas takes place.

There have been those who have declared that those who handle such

weapons will be far more subject to moral and indeed physical effect

than those against whom they are directed, and though this may be true

of certain navies it is certainly not true of the British.

It would be possible to quote many instances, both of cases in which

submarine defences have prevented the carrying out of certain operations

and also of other cases where they have been disregarded. Just as there

have been audacious burglaries in spite of “Beware of the dog” notices,

so there have been daring attacks in spite of known submarine defences.

There is always in warfare the possibility that the mine may fail to act

at the critical moment, that the torpedo may not succeed in firing its

mark and that the submarine boat may miss its prey.

The first occasion on which the moral influence of modern under-water

methods of warfare made itself felt was during the American Civil War.

The story of Admiral Farragut’s entrance into Mobile Bay, on August 5,

1864, is a well-known instance of a commander advancing in spite of

known dangers beneath the waves. It has been admirably told in the life

of the Admiral by Captain A. T. Mahan. The channel was known to be sown

with mines and one of his ships, the _Tecumseh_, had been sent to the

bottom already by one of these unseen weapons. The Admiral reasoned

thus: “The chances are that I shall lose some of my vessels by torpedoes

or the guns of the enemy, but with some of my fleet afloat I shall

eventually be successful. I cannot lose all. I will attack regardless of

consequences and never turn back.” As the _Hartford_ passed the

_Brooklyn_ a warning cry came from the latter that there were torpedoes

ahead.

“Damn the torpedoes!” shouted the Admiral in the exaltation of his high

purpose. “Four bells! Captain Drayton, go ahead. Jouett, full speed!”

The _Hartford_ and her consort crossed the line about 500 yards from

Mobile Point, well to the westward of the buoy and of the spot where the

_Tecumseh_ had gone down. As they passed between the buoys the cases of

the torpedoes were heard by many on board knocking against the copper of

the bottom, and many of the primers snapped audibly, but no torpedo

exploded.

The _Hartford_ went safely through, the gates of Mobile Bay were forced,

and as Farragut’s flag cleared the obstructions his last and hardest

battle was virtually won.

Mines had been plentifully sown by the Confederates, and across the deep

water 180 had been placed in a double line. The most effective were

those made of lager beer kegs coated with pitch and fitted with a number

of sensitive primers; the others had tin or iron covers, but they

corroded in the water and quickly became harmless. In addition, there

were three electro-contact mines which were to be exploded from Fort

Morgan. Had the mines been in an efficient state Admiral Farragut and

his fleet would assuredly have gone to the bottom. He took the risk—and

won.

Turning now to the other side of the picture it will be found that

hidden enemies are always the most dreaded, and that the history of

naval operations affords many examples of their moral influence

hindering the carrying out of certain operations.

In the actions off Charleston, in the American Civil War, the mines and

obstructions so influenced Admiral Dupont that he was content to

maintain the blockade instead of risking his ships against them.

One of the clearest cases of the moral influence of submarine mines

occurred during the Franco-Prussian War, when the French fleet were

prevented from entering Prussian harbours simply through fear of

submarine dangers. The naval campaign of 1870 consisted solely of the

watching by a strong French squadron of North German ships which had

taken refuge behind a reputed impassable barrier of subaqueous defences.

“The power of the French steamships,” writes Admiral Cyprian Bridge, “to

stand in within practicable range of their heavy guns, and do enormous

mischief to the rising naval establishment of the Bund as it then was,

was completely set at nought by the subaqueous defensive system which

the weaker force had devised to redress the inequality between it and

its rival. We shall do well to mark the results; the stronger navy did

and could do practically nothing; the smaller one preserved itself from

injuries, and at the close of the war still existed intact, as a nucleus

for that splendid force, which is now (October, 1878) third amongst the

navies of the world.”

During the Franco-German war the French fleet was kept off a fort by a

harbour protected by dummy mines. The story goes, that when the mines

arrived, the burgomaster was afraid to charge them, and laid them out

empty. At the completion of the war, when the dummies were taken up, the

burgomaster was congratulated by several consuls on the masterly way in

which he had performed his perilous task, no loss of life having been

caused.

There are so many instances of mines failing to explode or if exploding,

doing no damage, that naval officers may well declare that the submarine

mine is nothing but a “military bugbear.” In 1863, during the American

Civil War, the _New Ironsides_ halted off Fort Sumner, and just over a

submarine mine containing 2,000 lbs. of powder, which failed to explode

when fired from the battery, as one of the wires had been accidentally

severed by a waggon passing over it.

Instances of the moral influences of the torpedo are afforded by the two

most recent naval wars, the Chino-Japanese and the Spanish-American, and

by the manœuvres of the fleets of Great Britain, France, Germany, and

Russia.

Although the Chinese officers were quite unable to use the torpedo with

any effect, and evidently regarded the weapon as of more potential

danger to themselves than to the enemy, the Japanese commanders on more

than one occasion decided against certain movements, owing to a fear of

the Chinese torpedo flotilla.

During the Spanish-American war, the Americans suffered severely from

“torpedoites,” and were continually fancying they saw Spanish

torpedo-boats, and firing on them, when in reality there were none

present.

As an American officer remarked, “whatever the actual shortcomings of a

torpedo-boat flotilla, it must always act at least as an admirable

anti-soporific.” As to the Spaniards they appeared to dread the mines

they had themselves laid more than did the Americans.

One of the most amusing cases of the moral influences of torpedo warfare

was related by Vice-Admiral Sir Nowell Salmon at the Royal United

Service Institution in 1892.

Sir Nowell was discussing the question of the value of the electric

searchlight on battleships in warding off torpedo attack. He was

inclined to think that he would rather not have it at all, for on any

occasion that he had seen, whether it had been at a fixed station on

shore or whether it had been a fixed station on board, making a

quadrangle within which ships might lie, the torpedo station had always

been the point of attack, and had always suffered. In one case in which

he put a squadron inside four ships to make a path of light round them,

the ships showing the light were of course at once the point of attack,

and were all attacked and sunk; one commander indeed said that he was

sunk no less than seven times.

“I can remember a little incident in which I took part. It shows how

very curiously the electric light may act in some cases. The squadron

inside the rectangle of light was in total darkness, and my boat in

which I was inspecting the preparations happened to get within the beam

of one of the ships showing the light. Just as this happened, I saw a

boat inshore of me. I thought she was one of the attacking boats

steaming up inshore. Of course I set to work to cut her off, as I was

commanding the defending squadron. I steamed as hard as ever I could. I

got my muskets ready and so on. Still she went past me, going inshore as

I thought, and it was not until I recognised my own shadow shaking its

fist at the engineer for not clapping on more steam, that I found I was

chasing the shadow of my own boat thrown on the cliff. In a very few

seconds I should have been hard and fast ashore.”

“The real strength of the destroyer,” wrote a special correspondent with

the British fleet during the 1901 manœuvres, “consists not so much in

what she can do against large ships, certainly not in what she ever has

done so far, but in the fear entertained by her adversaries of the harm

she is held to be capable of doing. Her menace is tremendous, and really

paralysing to some minds.” This probably applies quite as much to

submarines as to destroyers.
