  Celts and Romans

  Advance of Roman Trade and Commerce into Free Gaul Of far greater importance was the contact of the Celtic nation with the Roman people, and with the Germans. We need not here repeat - what has been related already - how the Romans in their slow advance had gradually pressed back the Celts, had at last occupied the belt of coast between the Alps and the Pyrenees, and had thereby totally cut them off from Italy, Spain and the Mediterranean Sea - a catastrophe, for which the way had already been prepared centuries before by the laying out of the Hellenic stronghold at the mouth of the Rhone. But we must here recall the fact that it was not merely the superiority of the Roman arms which pressed hard on the Celts, but quite as much that of Roman culture, which likewise reaped the ultimate benefit of the respectable beginnings of Hellenic civilization in Gaul. Here too, as so often happens, trade and commerce paved the way for conquest. The Celt after northern fashion was fond of fiery drinks; the fact that like the Scythian he drank the generous wine unmingled and to intoxication, excited the surprise and the disgust of the temperate southern; but the trader has no objection to deal with such customers.

  Soon the trade with Gaul became a mine of gold for the Italian merchant; it was nothing unusual there for a jar of wine to be exchanged for a slave. Other articles of luxury, such as Italian horses, found advantageous sale in Gaul. There were instances even already of Roman burgesses acquiring landed property beyond the Roman frontier, and turning it to profit after the Italian fashion; there is mention, for example, of Roman estates in the canton of the Segusiavi (near Lyons) as early as about 673. Beyond doubt it was a consequence of this that, as already mentioned[24] in free Gaul itself, e. g. among the Arverni, the Roman language was not unknown even before the conquest; although this knowledge was presumably still restricted to few, and even the men of rank in the allied canton of the Haedui had to be conversed with through interpreters. Just as the traffickers in fire-water and the squatters led the way in the occupation of North America, so these Roman wine-traders and landlords paved the way for, and beckoned onward, the future conqueror of Gaul. How vividly this was felt even on the opposite side, is shown by the prohibition which one of the most energetic tribes of Gaul, the canton of the Nervii, like some German peoples, issued against trafficking with the Romans.

  Celts and Germans

  Still more violent even than the pressure of the Romans from the Mediterranean was that of the Germans downward from the Baltic and the North Sea - a fresh stock from the great cradle of peoples in the east, which made room for itself by the side of its elder brethren with youthful vigour, although also with youthful rudeness. Though the tribes of this stock dwelling nearest to the Rhine - the Usipetes, Tencteri, Sugambri, Ubii - had begun to be in some degree civilized, and had at least ceased voluntarily to change their abodes, all accounts yet agree that farther inland agriculture was of little importance, and the several tribes had hardly yet attained fixed abodes. It is significant in this respect that their western neighbours at this time hardly knew how to name any one of the peoples of the interior of Germany by its cantonal name; these were only known to them under the general appellations of the Suebi, that is, the roving people or nomads, and the Marcomani, that is, the land-guard[25] - names which were hardly cantonal names in Caesar's time, although they appeared as such to the Romans and subsequently became in various cases names of cantons.

  The Right Bank of the Rhine Lost to the Celts

  The most violent onset of this great nation fell upon the Celts. The struggles, in which the Germans probably engaged with the Celts for the possession of the regions to the east of the Rhine, are wholly withdrawn from our view. We are only able to perceive, that about the end of the seventh century of Rome all the land as far as the Rhine was already lost to the Celts; that the Boii, who were probably once settled in Bavaria and Bohemia[26], were homeless wanderers; and that even the Black Forest formerly possessed by the Helvetii[27], if not yet taken possession of by the German tribes dwelling in the vicinity, was at least waste debateable border-land, and was presumably even then, what it was afterwards called, the Helvetian desert The barbarous strategy of the Germans - which secured them from hostile attacks by laying waste the neighbourhood for miles - seems to have been applied here on the greatest scale.

  German Tribes on the Left Bank of the Rhine

  But the Germans had not remained stationary at the Rhine. The march of the Cimbrian and Teutonic host, composed, as respects its flower, of German tribes, which had swept with such force fifty years before over Pannonia, Gaul, Italy, and Spain, seemed to have been nothing but a grand reconnaissance. Already different German tribes had formed permanent settlements to the west of the Rhine, especially of its lower course; having intruded as conquerors, these settlers continued to demand hostages and to levy annual tribute from the Gallic inhabitants in their neighbourhood, as if from subjects. Among these German tribes were the Aduatuci, who from a fragment of the Cimbrian horde[28] had grown into a considerable canton, and a number of other tribes afterwards comprehended under the name of the Tungri on the Maas in the region of Liege; even the Treveri (about Treves) and the Nervii (in Hainault), two of the largest and most powerful peoples of this region, are directly designated by respectable authorities as Germans. The complete credibility of these accounts must certainly remain doubtful, since, as Tacitus remarks in reference to the two peoples last mentioned, it was subsequently, at least in these regions, reckoned an honour to be descended of German blood and not to belong to the little-esteemed Celtic nation; yet the population in the region of the Scheldt, Maas, and Moselle seems certainly to have become, in one way or another, largely mingled with German elements, or at any rate to have come under German influences.

  The German settlements themselves were perhaps small; they were not unimportant, for amidst the chaotic obscurity, through which we see the stream of peoples on the right bank of the Rhine ebbing and flowing about this period, we can well perceive that larger German hordes were preparing to cross the Rhine in the track of these advanced posts. Threatened on two sides by foreign domination and torn by internal dissension, it was scarcely to be expected that the unhappy Celtic nation would now rally and save itself by its own vigour. Dismemberment, and decay in virtue of dismemberment, had hitherto been its history; how should a nation, which could name no day like those of Marathon and Salamis, of Aricia and the Raudine plain - a nation which, even in its time of vigour, had made no attempt to destroy Massilia by a united effort - now when evening had come, defend itself against so formidable foes?

  The Roman Policy with Reference to the German Invasion

  The less the Celts, left to themselves, were a match for the Germans, the more reason had the Romans carefully to watch over the complications in which the two nations might be involved. Although the movements thence arising had not up to the present time directly affected them, they and their most important interests were yet concerned in the issue of those movements. As may readily be conceived, the internal demeanour of the Celtic nation had become speedily and permanently influenced by its outward relations. As in Greece the Lacedaemonian party combined with Persia against the Athenians, so the Romans from their first appearance beyond the Alps had found a support against the Arverni, who were then the ruling power among the southern Celts, in their rivals for the hegemony, the Haedui: and with the aid of these new "brothers of the Roman natio", they had not merely reduced to subjection the Allobroges and a great portion of the indirect territory of the Arverni, but had also, in the Gaul that remained free, occasioned by their influence the transference of the hegemony from the Arverni to these Haedui. But while the Greeks were threatened with danger to their nationality only from one side, the Celts found themselves hard pressed simultaneously by two national foes; and it was natural that they should seek from the one protection against the other, and that, if the one Celtic party attached itself to the Romans, their opponents should on the contrary form alliance with the Germans. Thi
s course was most natural for the Belgae, who were brought by neighbourhood and manifold intermixture into closer relation to the Germans who had crossed the Rhine, and moreover, with their less-developed culture, probably felt themselves at least as much akin to the Suebian of alien race as to their cultivated Allobrogian or Helvetic countryman. But the southern Celts also, among whom now as already mentioned, the considerable canton of the Sequani (about Besangon) stood at the head of the party hostile to the Romans, had every reason at this very time to call in the Germans against the Romans who immediately threatened them; the remiss government of the senate and the signs of the revolution preparing in Rome, which had not remained unknown to the Celts, made this very moment seem suitable for ridding themselves of the Roman influence and primarily for humbling the Roman clients, the Haedui. A rupture had taken place between the two cantons respecting the tolls on the Saone, which separated the territory of the Haedui from that of the Sequani, and about the year 683 the German prince Ariovistus with some 15,000 armed men had crossed the Rhine as condottiere of the Sequani.

  Ariovistus on the Middle Rhine

  The war was prolonged for some years with varying success; on the whole the results were unfavourable to the Haedui. Their leader Eporedorix at length called out their whole clients, and marched forth with an enormous superiority of force against the Germans. These obstinately refused battle, and kept themselves under cover of morasses and forests. It was not till the clans, weary of waiting, began to break up and disperse, that the Germans appeared in the open field, and then Ariovistus compelled a battle at Admagetobriga, in which the flower of the cavalry of the Haedui were left on the field. The Haedui, forced by this defeat to conclude peace on the terms which the victor proposed, were obliged to renounce the hegemony, and to consent with their whole adherents to become clients of the Sequani; they had to bind themselves to pay tribute to the Sequani or rather to Ariovistus, and to furnish the children of their principal nobles as hostages; and lastly they had to swear that they would never demand back these hostages nor invoke the intervention of the Romans.

  Inaction of the Romans

  This peace was concluded apparently about 693[29]. Honour and advantage enjoined the Romans to come forward in opposition to it; the noble Haeduan Divitiacus, the head of the Roman party in his clan, and for that reason now banished by his countrymen, went in person to Rome to solicit their intervention. A still more serious warning was the insurrection of the Allobroges in 693[30] - the neighbours of the Sequani - which was beyond doubt connected with these events. In reality orders were issued to the Gallic governors to assist the Haedui; they talked of sending consuls and consular armies over the Alps; but the senate, to whose decision these affairs primarily fell, at length here also crowned great words with little deeds. The insurrection of the Allobroges was suppressed by arms, but nothing was done for the Haedui; on the contrary, Ariovistus was even enrolled in 695 in the list of kings friendly with the Romans[31].

  Foundation of a German Empire in Gaul

  The German warrior-prince naturally took this as a renunciation by the Romans of the Celtic land which they had not occupied; he accordingly took up his abode there, and began to establish a German principality on Gallic soil. It was his intention that the numerous bands which he had brought with him, and the still more numerous bands that afterwards followed at his call from home - it was reckoned that up to 696 some 120,000 Germans had crossed the Rhine - this whole mighty immigration of the German nation, which poured through the once opened sluices like a stream over the beautiful west, should become settled there and form a basis on which he might build his dominion over Gaul. The extent of the German settlements which he called into existence on the left bank of the Rhine cannot be determined; beyond doubt it was great, and his projects were far greater still. The Celts were treated by him as a wholly subjugated nation, and no distinction was made between the several cantons. Even the Sequani, as whose hired commander-in-chief he had crossed the Rhine, were obliged, as if they were vanquished enemies, to cede to him for his people a third of their territory - presumably upper Alsace afterwards inhabited by the Triboci - where Ariovistus permanently settled with his followers; nay, as if this were not enough, a second third was afterwards demanded of them for the Harudes who arrived subsequently. Ariovistus seemed as if he wished to take up in Gaul the part of Philip of Macedonia, and to play the master over the Celts who were friendly to the Germans no less than over those who adhered to the Romans.

  The Germans on the Lower Rhine - The Germans on the Upper Rhine

  Spread of the Helvetian Invasion to the Interior of Gaul The appearance of the energetic German prince in so dangerous proximity, which could not but in itself excite the most serious apprehension in the Romans, appeared still more threatening, inasmuch as it stood by no means alone. The Usipetes and Tencteri settled on the right bank of the Rhine, weary of the incessant devastation of their territory by the overbearing Suebian tribes, had, the year before Caesar arrived in Gaul (695), set out from their previous abodes to seek others at the mouth of the Rhine.

  They had already taken away from the Menapii there the portion of their territory situated on the right bank, and it might be foreseen that they would make the attempt to establish themselves also on the left. Suebian bands, moreover, assembled between Cologne and Mayence, and threatened to appear as uninvited guests in the opposite Celtic canton of the Treveri. Lastly, the territory of the most easterly clan of the Celts, the warlike and numerous Helvetii, was visited with growing frequency by the Germans, so that the Helvetii, who perhaps even apart from this were suffering from over-population through the reflux of their settlers from the territory which they had lost to the north of the Rhine, and besides were liable to be completely isolated from their kinsmen by the settlement of Ariovistus in the territory of the Sequani, conceived the desperate resolution of voluntarily evacuating the territory hitherto in their possession to the Germans, and acquiring larger and more fertile abodes to the west of the Jura, along with, if possible, the hegemony in the interior of Gaul - a plan which some of their districts had already formed and attempted to execute during the Cimbrian invasion[32].

  the Rauraci whose territory (Basle and southern Alsace) was similarly threatened, the remains, moreover, of the Boii who had already at an earlier period been compelled by the Germans to forsake their homes and were now unsettled wanderers, and other smaller tribes, made common cause with the Helvetii. As early as 693 their flying parties came over the Jura and even as far as the Roman province; their departure itself could not be much longer delayed; inevitably German settlers would then advance into the important region between the lakes of Constance and Geneva forsaken by its defenders. From the sources of the Rhine to the Atlantic Ocean the German tribes were in motion; the whole line of the Rhine was threatened by them; it was a moment like that when the Alamanni and the Franks threw themselves on the falling empire of the Caesars; and even now there seemed on the eve of being carried into effect against the Celts that very movement which was successful five hundred years afterwards against the Romans.

  Caesar Proceeds to Gaul - Caesar's Army

  Under these circumstances the new governor Gaius Caesar arrived in the spring of 696 in Narbonese Gaul, which had been added by decree of the senate to his original province embracing Cisalpine Gaul along with Istria and Dalmatia. His office, which was committed to him first for five years (to the end of 700), then in 699 for five more (to the end of 705), gave him the right to nominate ten lieutenants of propraetorian rank, and (at least according to his own interpretation) to fill up his legions, or even to form new ones at his discretion out of the burgess-population - who were especially numerous in Cisalpine Gaul - of the territory under his sway. The army, which he received in the two provinces, consisted, as regards infantry of the line, of four legions trained and inured to war, the seventh, eighth, ninth, and tenth, or at the utmost 24,000 men, to which fell to be added, as usual, the contingents of the subje
cts. The cavalry and light-armed troops, moreover, were represented by horsemen from Spain, and by Numidian, Cretan, and Balearic archers and slingers. The staff of Caesar - the elite of the democracy of the capital - contained, along with not a few useless young men of rank, some able officers, such as Publius Crassus the younger son of the old political ally of Caesar, and Titus Labienus, who followed the chief of the democracy as a faithful adjutant from the Forum to the battle-field. Caesar had not received definite instructions; to one who was discerning and courageous these were implied in the circumstances with which he had to deal. Here too the negligence of the senate had to be retrieved, and first of all the stream of migration of the German peoples had to be checked.

  Repulse of the Helvetii

  Just at this time the Helvetic invasion, which was closely interwoven with the German and had been in preparation for years, began. That they might not make a grant of their abandoned huts to the Germans and might render their own return impossible, the Helvetii had burnt their towns and villages; and their long trains of waggons, laden with women, children, and the best part of their moveables, arrived from all sides at the Leman lake near Genava (Geneva), where they and their comrades had fixed their rendezvous for the 28th of March[33] of this year. According to their own reckoning the whole body consisted of 368,000 persons, of whom about a fourth part were able to bear arms. As the mountain chain of the Jura, stretching from the Rhine to the Rhone, almost completely closed in the Helvetic country towards the west, and its narrow defiles were as ill adapted for the passage of such a caravan as they were well adapted for defence, the leaders had resolved to go round in a southerly direction, and to open up for themselves a way to the west at the point, where the Rhone has broken through the mountain-chain between the south-western and highest part of the Jura and the Savoy mountains, near the modern Fort de l'Ecluse. But on the right bank here the rocks and precipices come so close to the river that there remained only a narrow path which could easily be blocked up, and the Sequani, to whom this bank belonged, could with ease intercept the route of the Helvetii. They preferred therefore to pass over, above the point where the Rhone breaks through, to the left Allobrogian bank, with the view of regaining the right bank further down the stream where the Rhone enters the plain, and then marching on towards the level west of Gaul; there the fertile canton of the Santones (Saintonge, the valley of the Charente) on the Atlantic Ocean was selected by the wanderers for their new abode. This march led, where it touched the left bank of the Rhone, through Roman territory; and Caesar, otherwise not disposed to acquiesce in the establishment of the Helvetii in western Gaul, was firmly resolved not to permit their passage. But of his four legions three were stationed far off at Aquileia; although he called out in haste the militia of the Transalpine province, it seemed scarcely possible with so small a force to hinder the innumerable Celtic host from crossing the Rhone, between its exit from the Leman lake at Geneva and the point of its breaking through the mountains, over a distance of more than fourteen miles. Caesar, however, by negotiations with the Helvetii, who would gladly have effected by peaceable means the crossing of the river and the march through the Allobrogian territory, gained a respite of fifteen days, which was employed in breaking down the bridge over the Rhone at Genava, and barring the southern bank of the Rhone against the enemy by an entrenchment nearly nineteen miles long: it was the first application of the system - afterwards carried out on so immense a scale by the Romans - of guarding the frontier of the empire in a military point of view by a chain of forts placed in connection with each other by ramparts and ditches. The attempts of the Helvetii to gain the other bank at different places in boats or by means of fords were successfully frustrated by the Romans in these lines, and the Helvetii were compelled to desist from the passage of the Rhone.
