But when he ceased from the pursuit and turned against Bibracte, the Helvetii thought that the Romans were making preparations for flight, and now attacked in their turn.
Battle At Bibracte
Caesar desired nothing better. The two armies posted themselves on two parallel chains of hills; the Celts began the engagement, broke up the Roman cavalry which had advanced into the plain, and rushed on against the Roman legions posted on the slope of the hill, but were there obliged to give way before Caesar's veterans. When the Romans thereupon, following up their advantage, descended in their turn to the plain, the Celts again advanced against them, and a reserved Celtic corps took them at the same time in flank. The reserve of the Roman attacking column was pushed forward against the latter; it forced it away from the main body towards the baggage and the barricade of waggons, where it was destroyed. The bulk of the Helvetic host was at length brought to give way, and compelled to beat a retreat in an easterly direction--the opposite of that towards which their expedition led them. This day had frustrated the scheme of the Helvetii to establish for themselves new settlements on the Atlantic Ocean, and handed them over to the pleasure of the victor; but it had been a hot day also for the conquerors. Caesar, who had reason for not altogether trusting his staff of officers, had at the very outset sent away all the officers' horses, so as to make the necessity of holding their ground thoroughly clear to his troops; in fact the battle, had the Romans lost it, would have probably brought about the annihilation of the Roman army. The Roman troops were too much exhausted to pursue the conquered with vigour; but in consequence of the proclamation of Caesar that he would treat all who should support the Helvetii as like the Helvetii themselves enemies of the Romans, all support was refused to the beaten army whithersoever it went-- in the first instance, in the canton of the Lingones (about Langres)--and, deprived of all supplies and of their baggage and burdened by the mass of camp-followers incapable of fighting, they were under the necessity of submitting to the Roman general.
The Helvetii Sent Back To Their Original Abode
The lot of the vanquished was a comparatively mild one. The Haedui were directed to concede settlements in their territory to the homeless Boii; and this settlement of the conquered foe in the midst of the most powerful Celtic cantons rendered almost the services of a Roman colony. The survivors of the Helvetii and Rauraci, something more than a third of the men that had marched forth, were naturally sent back to their former territory. It was incorporated with the Roman province, but the inhabitants were admitted to alliance with Rome under favourable conditions, in order to defend, under Roman supremacy, the frontier along the upper Rhine against the Germans. Only the south-western point of the Helvetic canton was directly taken into the possession of the Romans, and there subsequently, on the charming shore of the Leman lake, the old Celtic town Noviodunum (now Nyon) was converted into a Roman frontier-fortress, the "Julian equestrian colony."(35)
Caesar And Ariovistus Negotiations
Thus the threatening invasion of the Germans on the upper Rhine was obviated, and, at the same time, the party hostile to the Romans among the Celts was humbled. On the middle Rhine also, where the Germans had already crossed years ago, and where the power of Ariovistus which vied with that of Rome in Gaul was daily spreading, there was need of similar action, and the occasion for a rupture was easily found. In comparison with the yoke threatened or already imposed on them by Ariovistus, the Roman supremacy probably now appeared to the greater part of the Celts in this quarter the lesser evil; the minority, who retained their hatred of the Romans, had at least to keep silence. A diet of the Celtic tribes of central Gaul, held under Roman influence, requested the Roman general in name of the Celtic nation for aid against the Germans. Caesar consented. At his suggestion the Haedui stopped the payment of the tribute stipulated to be paid to Ariovistus, and demanded back the hostages furnished; and when Ariovistus on account of this breach of treaty attacked the clients of Rome, Caesar took occasion thereby to enter into direct negotiation with him and specially to demand, in addition to the return of the hostages and a promise to keep peace with the Haedui, that Ariovistus should bind himself to allure no more Germans over the Rhine. The German general replied to the Roman, in the full consciousness of equality of rights, that northern Gaul had become subject to him by right of war as fairly as southern Gaul to the Romans; and that, as he did not hinder the Romans from taking tribute from the Allobroges, so they should not prevent him from taxing his subjects. In later secret overtures it appeared that the prince was well aware of the circumstances of the Romans; he mentioned the invitations which had been addressed to him from Rome to put Caesar out of the way, and offered, if Caesar would leave to him northern Gaul, to assist him in turn to obtain the sovereignty of Italy--as the party-quarrels of the Celtic nation had opened up an entrance for him into Gaul, he seemed to expect from the party- quarrels of the Italian nation the consolidation of his rule there. For centuries no such language of power completely on a footing of equality and bluntly and carelessly expressing its independence had been held in presence of the Romans, as was now heard from the king of the German host; he summarily refused to come, when the Roman general suggested that he should appear personally before him according to the usual practice with client-princes.
Ariovistus Attacked And Beaten
It was the more necessary not to delay; Caesar immediately set out against Ariovistus. A panic seized his troops, especially his officers when they were to measure their strength with the flower of the German troops that for fourteen years had not come under shelter of a roof: it seemed as if the deep decay of Roman moral and military discipline would assert itself and provoke desertion and mutiny even in Caesar's camp.
