Gallic War (7.67-7.70)

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 .

The town itself was situated on the top of a hill, in a very lofty position, so that it did not appear likely to be taken, except by a regular siege. Two rivers, on two different sides, washed the foot of the hill. Before the town lay a plain of about three miles in length; on every other side hills at a moderate distance, and of an equal degree of height, surrounded the town. The army of the Gauls had filled all the space under the wall, comprising a part of the hill which looked to the rising sun, and had drawn in front a trench and a stone wall six feet high. The circuit of that fortification, which was commenced by the Romans, comprised eleven miles. The camp was pitched in a strong position, and twenty-three redoubts were raised in it, in which sentinels were placed by day, lest any sally should be made suddenly; and by night the same were occupied by watches and strong guards.

The work having been begun, a cavalry action ensues in that plain, which we have already described as broken by hills, and extending three miles in length. The contest is maintained on both sides with the utmost vigor; Caesar sends the Germans to aid our troops when distressed, and draws up the legions in front of the camp, lest any sally should be suddenly made by the enemy's infantry. The courage of our men is increased by the additional support of the legions; the enemy being put to flight, hinder one another by their numbers, and as only the narrower gates were left open, are crowded together in them; then the Germans pursue them with vigor even to the fortifications. A great slaughter ensues; some leave their horses, and endeavor to cross the ditch and climb the wall. Caesar orders the legions which he had drawn up in front of the rampart to advance a little. The Gauls, who were within the fortifications, were no less panic-stricken, thinking that the enemy were coming that moment against them, and unanimously shout "to arms;" some in their alarm rush into the town; Vercingetorix orders the gates to be shut, lest the camp should be left undefended. The Germans retreat, after slaying many and taking several horses.
