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 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. This 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.
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.
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].
28. IV. V. Teutones in the Province of Gaul.
29. The arrival of Ariovistus in Gaul has been placed, according to Caesar, i. 36, in 683, and the battle of Admagetobriga (for such was the name of the place now usually, in accordance with a false inscription, called Magetobriga), according to Caesar i. 35 and Cicero Ad. Att. i. 19, in 693.
30. V. VII. Wars and Revolts There.
31. That we may not deem this course of things incredible, or even impute to it deeper motives than ignorance and laziness in statesmen, we shall do well to realize the frivolous tone in which a distinguished senator like Cicero expresses himself in his correspondence respecting these important Transalpine affairs.
