Gallic War

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."

This proposal receiving general approbation, and all being forced to take the oath, on the next day the cavalry were divided into three parts, and two of these divisions made a demonstration on our two flanks; while one in front began to obstruct our march. On this circumstance being announced, Caesar orders his cavalry also to form three divisions and charge the enemy. Then the action commences simultaneously in every part: the main body halts; the baggage is received within the ranks of the legions. If our men seemed to be distressed, or hard pressed in any quarter, Caesar usually ordered the troops to advance, and the army to wheel round in that quarter; which conduct retarded the enemy in the pursuit, and encouraged our men by the hope of support. At length the Germans, on the right wing, having gained the top of the hill, dislodge the enemy from their position and pursue them even as far as the river at which Vercingetorix with the infantry was stationed, and slay several of them. The rest, on observing this action, fearing lest they should be surrounded, betake themselves to flight. A slaughter ensues in every direction, and three of the noblest of the Aedui are taken and brought to Caesar: Cotus, the commander of the cavalry, who had been engaged in the contest with Convictolitanis the last election, Cavarillus, who had held the command of the infantry after the revolt of Litavicus, and Eporedirix, under whose command the Aedui had engaged in war against the Sequani, before the arrival of Caesar.

All his cavalry being routed, Vercingetorix led back his troops in the same order as he had arranged them before the camp, and immediately began to march to Alesia , which is a town of the Mandubii, and ordered the baggage to be speedily brought forth from the camp, and follow him closely. Caesar, having conveyed his baggage to the nearest hill, and having left two legions to guard it, pursued as far as the time of day would permit, and after slaying about three thousand of the rear of the enemy, encamped at Alesia on the next day. On reconnoitering the situation of the city, finding that the enemy were panic-stricken, because the cavalry in which they placed their chief reliance, were beaten, he encouraged his men to endure the toil, and began to draw a line of circumvallation round Alesia .
