Gallic War (7.63-7.66)

The revolt of the Aedui being known, the war grows more dangerous. Embassies are sent by them in all directions: as far as they can prevail by influence, authority, or money, they strive to excite the state [to revolt]. Having got possession of the hostages whom Caesar had deposited with them, they terrify the hesitating by putting them to death. The Aedui request Vercingetorix to come to them and communicate his plans of conducting the war. On obtaining this request they insist that the chief command should be assigned to them; and when the affair became a disputed question, a council of all Gaul is summoned to Bibracte . They came together in great numbers and from every quarter to the same place. The decision is left to the votes of the mass; all to a man approve of Vercingetorix as their general. The Remi , Lingones , and Treviri were absent from this meeting; the two former because they attached themselves to the alliance of Rome ; the Treviri because they were very remote and were hard pressed by the Germans; which was also the reason of their being absent during the whole war, and their sending auxiliaries to neither party. The Aedui are highly indignant at being deprived of the chief command; they lament the change of fortune, and miss Caesar's indulgence toward them; however, after engaging in the war, they do not dare to pursue their own measures apart from the rest. Eporedirix and Viridomarus, youths of the greatest promise, submit reluctantly to Vercingetorix.

The latter demands hostages from the remaining states; nay, more, appointed a day for this proceeding; he orders all the cavalry, fifteen thousand in number, to quickly assemble here; he says that he will be content with the infantry which he had before, and would not tempt fortune nor come to a regular engagement; but since he had abundance of cavalry, it would be very easy for him to prevent the Romans from obtaining forage or corn, provided that they themselves should resolutely destroy their corn and set fire to their houses; by which sacrifice of private property they would evidently obtain perpetual dominion and freedom. After arranging these matters, he levies ten thousand infantry on the Aedui and Segusiani, who border on our province: to these he adds eight hundred horse. He sets over them the brother of Eporedirix, and orders him to wage war against the Allobroges. On the other side he sends the Gabali and the nearest cantons of the Arverni against the Helvii; he likewise sends the Ruteni and Cadurci to lay waste the territories of the Volcae Arecomici. Besides, by secret messages and embassies, he tampers with the Allobroges, whose minds, he hopes, had not yet settled down after the excitement of the late war. To their nobles he promises money, and to their state the dominion of the whole province.

The only guards provided against all these contingencies were twenty-two cohorts, which were collected from the entire province by Lucius Caesar, the lieutenant, and opposed to the enemy in every quarter. The Helvii, voluntarily engaging in battle with their neighbors, are defeated, and Caius Valerius Donotaurus, the son of Caburus, the principal man of the state, and several others, being slain, they are forced to retire within their towns and fortifications. The Allobroges, placing guards along the course of the Rhine , defend their frontiers with great vigilance and energy. Caesar, as he perceived that the enemy were superior in cavalry, and he himself could receive no aid from the Province or Italy, while all communication was cut off, sends across the Rhine into Germany to those states which he had subdued in the preceding campaigns, and summons from them cavalry and the light-armed infantry, who were accustomed to engage among them. On their arrival, as they were mounted on unserviceable horses, he takes horses from the military tribunes and the rest, nay, even from the Roman knights and veterans, and distributes them among the Germans.

In the mean time, whilst these things are going on, the forces of the enemy from the Arverni, and the cavalry which had been demanded from all Gaul, meet together. A great number of these having been collected, when Caesar was marching into the country of the Sequani, through the confines of the Lingones , in order that he might the more easily render aid to the province, Vercingetorix encamped in three camps, about ten miles from the Romans: and having summoned the commanders of the cavalry to a council, he shows that the time of victory was come; that the Romans were fleeing into the Province and leaving Gaul; that this was sufficient for obtaining immediate freedom; but was of little moment in acquiring peace and tranquillity for the future; for the Romans would return after assembling greater forces and would not put an end to the war. Therefore they should attack them on their march, when encumbered. If the infantry should [be obliged to] relieve their cavalry, and be retarded by doing so, the march could not be accomplished: if, abandoning their baggage they should provide for their safety (a result which, he trusted, was more like to ensue), they would lose both property and character. For as to the enemy's horse, they ought not to entertain a doubt that none of them would dare to advance beyond the main body. In order that they [the Gauls] may do so with greater spirit, he would marshal all their forces before the camp, and intimidate the enemy. The cavalry unanimously shout out, "That they ought to bind themselves by a most sacred oath, that he should not be received under a roof, nor have access to his children, parents, or wife, who shall not twice have ridden through the enemy's army."
