The Romans in the reign of Augustus were, so far as military matters

are concerned, and indeed, in most other respects, very much in our

own position at the present day. Just as we thoughtlessly and unjustly

estimate the exploits of our soldiers in the Soudan, on the North-West

frontier of India, on the West Coast of Africa, and even in South

Africa, rather cheaply, and disparage their achievements in comparison

with those of Marlborough and Wellington, so the contemporaries of

Augustus looked back with regret to the heroes of the Punic Wars and

the conquerors of Greece; they did not realize that the work which

was to be done in their own time was far more difficult than the work

which had been done. We too forget that to win the Battle of Waterloo

was a trifle compared with the operations which led up to the victory

of Omdurman, and the double march into the Transvaal. The exploits of

Wellington in the Peninsula were splendid, impeded as they were by

opposition from England; but in the conquest of South Africa England

has grappled with far more serious difficulties, and her generals have

shown themselves at least as resourceful as Wellington.

The generals of the Augustan age are hardly known to us. Few class

Agrippa with the leading generals of the world, but the man who for the

first time organized the navy of the Roman Empire, who maintained the

organization of the army on such a footing that the enormous frontier

was never without its defenders, who was himself never beaten in the

field, and who trained a succession of capable officers to follow in

his footsteps, was no mean general. Similarly Tiberius and his brother,

along with many capable subordinates, waged successful campaigns under

conditions of peculiar difficulty for many years; but we never think

of them as great soldiers, because their exploits did not stir the

imagination of their contemporaries.

Vast though the Roman Empire was, its vulnerable frontiers were of

relatively small extent in the reign of Augustus; there was a weak

place at the sources of the Tigris and Euphrates; the Upper Nile had

its Soudanese difficulty then as now, but the whole of the North Coast

of Africa was protected by the desert, and the Mauretanian tribes were

not numerous enough really to imperil the strip of civilization along

the Mediterranean. Spain was all Roman and nearly all civilized, so was

Gaul; but between the mouths of the Rhine and the Bosphorus there was

a vast unsettled region, reaching down in one place to a point within

ten days’ journey of Rome itself, and along an unbroken line of many

hundred miles, threatening the cities of Macedonia and Greece. The

problem before Augustus and his generals was to form a frontier which

should permanently secure Gaul, Italy, and the Balkan Peninsula from

the adventurous races of central and East Central Europe.

The weakest point in the chain of defence was the Northern corner of

the Adriatic, and the increasing prosperity of the great plains of

the Po after they had become a Roman province naturally attracted the

attention of the semi-civilized tribes who lived in the hills along

the Dalmatian coast. Not only was there danger from the East, but the

valley of the Adige formed a gateway through which Central Europe

could pour its restless multitudes upon the Cis-Alpine Province. The

geographical configuration of the regions south of the plains of the

Eastern Danube has always impeded their progress, and to this very day

a patch of backward nationalities remains there in close proximity to

the most elaborately civilized states of Europe.

The other weak spot was the course of the Rhine, and especially the

country below the Drakensberg; that noble river for many miles from the

Lake of Constance formed a natural defence against the Germanic hordes,

but on reaching the flat land below Cologne it spread into marshes

and split into smaller channels, in which flotillas of boats could be

prepared without attracting notice, as was necessarily the case where

the river ran in a single stream. In fact it was practically found that

in places the Rhine was no barrier, and that the tribes on its Eastern

bank must be rolled back from the river, if Gaul was to enjoy her new

prosperity in peace.

It was in the defence of these two weak spots that Tiberius was to

fight his chief campaigns. In both regions security demanded that the

operations should be conducted far beyond the frontier, in country

difficult at the present day, and tenfold more difficult then, when

extensive forests and marshes were added to the impediments offered by

ravines and mountains.

It is not easy to estimate the degree of civilization reached by the

Pannonians and Dalmatians or the Germanic tribes, when they made war

upon the Roman legions. To the ancients all men living under tribal

or national institutions were barbarians; they restricted the honour

of civilization to those whose political constitution was based upon

the city, and though the Græco-Roman city organization practically

covered the two peninsulas, which we call Greece and Italy, it did not

elsewhere extend far inland; the outer fringe of cities was in close

contact with populations living under a clan system, whose chiefs or

kings adopted many of the luxuries and some of the institutions of

their neighbours; behind these again were less advanced nations and

less civilized rulers, gradually merging into real barbarism. The

Gallic chieftains had already been in frequent communication with Rome

for a century before Cæsar conquered Gaul, and the influence of the

Roman traders upon the general standard of civilization was perceptible

in his time even among the German tribes nearest to the Rhine. Arminius

had had a Roman education, Maroboduus was brought up by Augustus,

adopted the Roman military system and welcomed refugees who could train

his troops; Latin was already spoken by the Dalmatian tribes when

they were eventually conquered by Tiberius. Though the greater part

of Central Europe was under forest the valleys were cultivated, as

they were in Britain at the time of Cæsar’s invasions, but the forest

was always near enough to receive fugitives, and to give cover to an

attacking party. There were no large aggregations of human beings in

towns, but there were areas sufficiently thickly populated, and their

population was sufficiently well organized to bring formidable armies

into the field, whose operations were skilfully conducted. The men

were no more savages than the Boers are savages; their civilization

was a different civilization from the Græco-Roman, but it was a

civilization. The occurrences of the Highland Line were anticipated in

the foothills of the Alps; sometimes there was a mere cattle-lifting

raid, when a predecessor of Rob Roy swooped down upon the farms round

Mantua or Cremona, sometimes a combination of clans under a capable

chieftain waged a formidable war, whose object was less plunder than

the preservation of their independence; sometimes the pressure of real

savagery from behind urged the more civilized races forward till the

ultimate wave fell upon the Roman frontier.

Far in the East round the mouths of the Danube the predecessors of the

Cossacks on their little horses kept the Roman outposts in a state of

terror. Ovid tells us how they swooped down upon the labourers in the

fields round the camp at Tomi, how their arrows fell into its very

centre, how they galloped round its walls, picked up some unfortunate

straggler, and were off with him before pursuit could be organized.

Reading such a description as this we realize the true significance

of the two Roman walls in England, and the wall from the Main to the

Danube in Germany. They were not defences against systematic war; they

were too long to be defended against an organized invasion, but they

effectually prevented raiding. Cattle cannot be lifted over a wall

twelve feet high. The difference between our frontier wars and the

Roman frontier wars lies in the proximity of the Roman frontiers to the

heart of the Empire; but in spite of the perpetual imminence of the

danger, the Romans did not pay a sufficient tribute of gratitude to the

generals who secured their safety, and were inclined to underestimate

their services.

Even such a clear-sighted historian as Merivale, in speaking of the

military operations of Tiberius and Drusus in Germany, adopts the

attitude of Tacitus, and disparages the cautious policy of Augustus,

which discouraged schemes of boundless conquest in Central Europe.

Tacitus wrote, when Trajan was engaged in rectifying the frontier

of the Lower Danube, new dangers threatened the Empire and new

measures seemed advisable. The men of his day might be pardoned for

thinking that they were called upon to do what Augustus had unwisely

left undone. Possibly they were right, but they omitted from their

calculations a fact which was of the first importance, and of itself

imposed prudence. The fighting strength of the Empire was not adequate

for a policy of indefinite expansion at the end of the reign of

Augustus, nor even in its middle period. It was difficult to steer

between the two extremes. Augustus had seen the evils of a rampant

military policy in the careers of his uncle and Antonius; he had known

what it was to be the puppet of his own soldiers; he had fought in the

Civil Wars, and he rightly inferred that there could be no settled

government so long as the sword outbalanced the gown. Quite apart

from any personal ambition or mean motive, he shrank from creating

fresh military heroes, who might be tempted to overthrow the carefully

balanced fabric of the State, and renew the Marian and Sullan episodes,

or the hateful reign of the Triumvirate in which he had himself taken

an unwilling part. On the other hand, a certain strength was necessary

to police the Empire and guard its frontiers. In the encouragement

which he gave to civilians in the public service, in the revival of

commerce, and the abundance of employment secured by the internal peace

of the Empire, Augustus cut off his supply of recruits; the army no

longer competed favourably with other employments, and year by year

the number of homeless and ruined men, to whom military service had

opened an opportunity, was reduced. Men were too precious to be lightly

ventured on interminable expeditions in the Hercynian forest, where the

elk, and possibly even the mammoth, still tested the ingenuity of the

hunter.

At the age of seventeen Tiberius accompanied Augustus and Agrippa

to Spain, where a campaign was conducted in the mountainous regions

occupied by the Cantabrians. Augustus soon fell ill and returned home,

but Tiberius remained to take his first lessons in war under the able

and ingenious Agrippa. The Romans wisely flung their young men into

active life at a very early age, and those who had it in them to

learn, had every opportunity of learning. Four years later Tiberius,

barely of age to manage his own affairs according to our ideas, was

put in command of the expedition which penetrated Armenia, and awed

the Parthians into a surrender of the captured standards. We are not

told that there was any serious fighting on this occasion; the triumph

was one of diplomacy rather than of arms, and the expedition itself

took the form of an armed demonstration strong enough to determine

the course of the negotiations rather than of a campaign. Doubtless

Tiberius was attended by capable advisers in addition to those splendid

centurions, the link between the commissioned and non-commissioned

officers, who formed the backbone of the Roman armies; but in any

case the experience was a valuable one. It was necessary that the

army should be conducted through a difficult and mountainous country,

far from its base; any negligence, any want of foresight, might have

brought on a disaster which, even if only temporary, would have spoiled

the effect contemplated, and weakened the Roman Plenipotentiaries. The

expedition was a better training than even a long course of autumn

manœuvres, and Tiberius returned from it with a full knowledge of

military problems.

The extraordinary indifference of the historians Paterculus and

Suetonius to chronology, and their absolutely casual use of such

connectives as “hereupon,” “soon afterwards,” and the like, makes it

difficult to be certain of the real sequence of events. It is, however,

certain that Tiberius was Governor of Transalpine Gaul for a year at

some period between B.C. 20 and B.C. 16, that he was harassed during

the term of his Governorship by sporadic invasions of German tribes,

and was able to measure their importance as affecting the peace of his

Province, and form plans for permanently checking them. He came to the

conclusion that the whole middle and eastern Alpine region was a centre

of disturbance, and that it could not be dealt with alone, seeing that

the tribes who lived on the Dalmatian coast and at the sources of the

Save were always ready to create a diversion when the Roman armies were

occupied in the valleys to the south or north-west of the Alps. Cæsar

had more than once been called back from the conquest of Gaul to deal

with the Pirustæ in the same quarter.

In B.C. 16 the ill-omened Marcus Lollius sustained a serious defeat at

the hands of the German tribes, while Gaul itself had been rendered

unquiet by the exactions of Licinus, himself a Gaul employed by

Augustus as Governor in the Southern Province. Augustus himself went

to Gaul to set straight the civilian administration, Agrippa was sent

to the Illyrian regions, Drusus to the passes leading from Lombardy to

the Upper Rhine, while Tiberius took charge of an expedition directed

upon the same region from Basle by the Lake of Constance. This was the

first of the great combined movements originated by Tiberius; their

conception, but even more their success, mark him out as a general of

genius. Given a mobile enemy able to live on the country, and provided

with an interminable area at his rear into which he can retreat, the

only hope of dealing with him successfully is to cut off his retreat.

This was the strategy of Tiberius.

The army of Agrippa in Illyria protected the rear of Drusus, who was

able to drive the Alpine tribes back through the passes to the Northern

face of the Alps, where they found the army of Tiberius ready for

them. The victory was so complete that the very names of these tribes

disappear from history; squeezed between two Roman armies they were

doubtless exterminated. Horace wrote an official ode on the occasion,

comparing Drusus to a young eagle or lion; and in a complimentary ode

to Augustus on another occasion, compared the charge of Tiberius to the

impetuous floods of the Aufidus, his native river. The northern slopes

of the Western Alps were now secured to Rome; there was no longer any

danger of Gallic intrigues stimulated by the restless Helvetii, but the

work was by no means done. Augustus seems to have remained for some

time in Gaul studying its social conditions, Agrippa remained in the

Illyrian district, Drusus was sent to the lower Rhine, and Tiberius,

as far as we can gather, remained at Rome.

Profiting by the experience gained in the recent war, Drusus determined

to repeat the strategy of Tiberius, and again to hem in an elusive

enemy between two Roman armies; he himself marched up the Lippe, making

a point on the Weser, somewhere near Paderborn, his objective, and at

the same time he sent a flotilla down the Rhine, with instructions

to ascend the mouth of the Weser, and thus cut off the flight of the

Germans. The first attempt failed, the fleet being dispersed by storms;

it was reserved for Tiberius himself to succeed at a later date in this

combined movement. In the following year Drusus advanced to the Weser,

and on his return established a permanent outpost at Aliso, fifty

miles up the Lippe; this was the period of the death of Agrippa, whose

command in Pannonia was taken over by Tiberius. We know but little of

the operations of Tiberius in Pannonia at this time, except that they

were successful, and that the ring of Roman provinces was now completed

along the East coast of the Adriatic, uniting Greece and Macedonia with

Italy.

In B.C. 10 Augustus returned to Gaul; Drusus consecrated a temple in

his honour at Lyons, and the worship of the Roman Empire personified

in Augustus was officially substituted for the Druidical religion, in

whose priesthood Augustus saw the irreconcilable enemy of Rome. After

this ceremony Drusus again crossed the Rhine and penetrated as far as

the Elbe; on his return he met with the accident which caused his

death, and elicited that touching illustration of affection on the part

of Tiberius, to which reference has already been made.

Tiberius took up his brother’s work on the Rhine and remained there

for two years; he has disappointed the historians by doing nothing

sensational, but when at the end of the two years Augustus called him

back to Rome to take the place of Imperial Colleague, he left the

Roman frontier extended, and the German terror pushed back from the

immediate vicinity of the river. He had created a Roman party among

the German chiefs, as Cæsar had created a Roman party among the Gallic

chiefs; partly as hostages, partly as friends, the young German nobles

were tempted to Rome to learn her civilization and form estimates of

her weakness; the Eastern bank of the river was sufficiently Romanized

to tempt Varus to treat it fifteen years later as a Roman province.

Tiberius did more than this: he began that policy which was eventually

to substitute for the magnificent conception of the all-embracing Roman

Empire the map of Europe; he transferred 40,000 Germans to the left

bank of the Rhine; they accepted the lands assigned to them, coupled

with the obligation to service in the armies of their conquerors. It

was a perilous policy, but no one could have foreseen its results in

the distant future, and even if its tendencies had been suspected at

the time, the pressing needs of the Empire would have silenced the

voice of a too clear-sighted critic. The Empire was short of soldiers;

men evaded military service by all possible means. Even the dreaded

slavery of the ergastula seemed to them less terrible than the army;

pay could not be found to make the soldier’s career sufficiently

attractive, now that the chances of loot and liberal donatives were

of the smallest. The finances of the Empire were straitened; Augustus

had had difficulty in adding a death duty of five per cent. to his

resources. The suggestion of Tiberius must have seemed a stroke of

genius: to protect the frontiers by civilizing the enemies of the

Empire, to find a cheap supply of soldiers by imposing military service

on the hardy Germans, gradually to relieve the manufacturer and the

merchant of the burden of finding men and taxes; no words could praise

too highly the man who had suggested a means by which these desirable

objects could be secured. We ourselves are treading in the same path;

we congratulate ourselves on the wisdom which made English soldiers of

Highland clansmen and Irish rapparees, which has arrayed against Russia

the tribes of the North-West frontier, which fights the barbarians of

Central Africa with the trained barbarians of its coasts; but we too

shall have to pay the price which the Roman paid, if we neglect the

military training of the centre of the Empire, and allow its population

to expand unexercised in arms, incapable of fighting. If ever the day

comes when the Sikhs and Goorkhas or even our own children beyond the

seas learn by experience that preponderant force is in their own hands,

and that the breed of fighting men is not ready for action in Great

Britain, the Empire of England will be broken up, as the Empire of

Rome was broken up; not by any sudden cataclysm, but by the gradual

intrusion of the less civilized and less trained components of the

Empire upon the central administration.

The end of the government of Tiberius upon the Rhine was also the

beginning of his retirement; his resumption of public work was almost

immediately followed by a fresh outbreak in the Pannonian region, and

then came a terrible disaster to the Roman arms in the district of the

Rhine. Of the campaigns which followed we fortunately have a fairly

clear account given us by an eyewitness, Paterculus.

Unfortunately the only work from the pen of Paterculus that has come

down to our times, perhaps the only work that he completed, is a short

epitome of Roman history from the beginning to A.D. 30, which seems

to have been written as an introduction to a work of considerable

detail dealing with the campaigns in which the author and the relatives

of his friend Marcus Vinicius, to whom the work is dedicated, took

part. Paterculus belonged to the class of professional soldiers and

administrators whom the Empire called into being, or to whom at least

it gave a position which they had not hitherto enjoyed. In his eyes

the Empire was good, and its rulers were good; and while he is profuse

in his admiration of the heroes of the old Republic, and can pay as

high a tribute to Cicero as to any supporter of the Empire, he is no

less commendatory of the men who were brought to the front by the new

order of things. He does not single out Tiberius as alone worthy of

praise; such men as Marcus Lepidus, the son of the triumvir, and others

who were in a position to excite the jealousy of a suspicious tyrant,

enjoy a full share of his somewhat exuberant laudation. We may admit

that Paterculus was uncritical without accusing him of deliberate

dishonesty; he was a successful man; he was in the swim; he had no

reason for nicely adjusting praise and censure to meet the merits of

the men with whom he worked; he was not a frequenter of the Legitimist

drawing rooms, but an active capable official, bluff, hearty, with an

unfortunate propensity to consider himself a stylist. His grandfather

was, as we have seen, an intimate friend and fellow soldier of the

father of Tiberius; his father was also a soldier; he himself followed

the family profession; he served under Caius Cæsar in Armenia, under

Agrippa in Pannonia, under Tiberius both in Germany and Pannonia; he

was honoured with civil magistracies at Rome, and eventually became a

Senator; his brother was similarly successful. His value to us lies in

the fact that he was an eyewitness of the events which he describes,

and we may be sure that the few details which he thought worthy of

mention in his rapid summary are actual facts. M. Vinicius was Consul

in A.D. 30, and the honour enjoyed by his friend prompted Paterculus to

write and dedicate this little work. In the following year the events

took place which brought about the fall of Sejanus, whom Paterculus

praises highly; possibly he was one of those upon whom the wrath of the

Senate fell; in any case we hear nothing more of him, and his proposed

work was never written, or never published; he died, or at any rate

ceased to speak, before the reign of terror which accompanied the fall

of Sejanus had cast its shadow upon Tiberius, before the reigns of

Caligula and Nero had made it possible to believe every evil of a Roman

Emperor, before the novelty of the Empire had worn off; there was no

reason for adopting any but an optimistic tone.

Tiberius left Rome for Germany in A.D. 4; war had been going on there

for three years, the Roman general being then a Marcus Vinicius,

grandfather of the Consul to whom Paterculus dedicated his book.

Paterculus accompanied Tiberius, and was generally with him during the

nine years of his campaigns; he seems to have been a member of the

headquarters staff, succeeding his father as commander of the cavalry.

He says: “For nine years in succession, either as cavalry commander

or staff officer, I was a spectator of his most heavenly operations,

and assisted him in the measure permitted by my own mediocrity.”

The epithet strikes us as exuberant, but it is frequently used by

Paterculus, and not reserved for Tiberius; he employs it in speaking of

the eloquence of Cicero. The historian tells us of the incidents of the

journey through the most populous regions of Italy and the provinces of

Gaul; he describes the joy with which the inhabitants welcomed their

former governor, while the soldiers pressed to seize his hand, and

shouted, “Do we really see you, General? Have we got you safe again?

I served with you in Armenia, I in Rhætia, I was rewarded by you in

Vindelicia, I in Pannonia, I in Germany.”
