Gallic War (7.79-7.82)

In the mean time, Commius and the rest of the leaders, to whom the supreme command had been intrusted, came with all their forces to Alesia , and having occupied the entire hill, encamped not more than a mile from our fortifications. The following day, having led forth their cavalry from the camp, they fill all that plain, which, we have related, extended three miles in length, and drew out their infantry a little from that place, and post them on the higher ground. The town Alesia commanded a view of the whole plain. The besieged run together when these auxiliaries were seen; mutual congratulations ensue, and the minds of all are elated with joy. Accordingly, drawing out their troops, they encamp before the town, and cover the nearest trench with hurdles and fill it up with earth, and make ready for a sally and every casualty.

Caesar, having stationed his army on both sides of the fortifications, in order that, if occasion should arise, each should hold and know his own post, orders the cavalry to issue forth from the camp and commence action. There was a commanding view from the entire camp, which occupied a ridge of hills; and the minds of all the soldiers anxiously awaited the issue of the battle. The Gauls had scattered archers and light-armed infantry here and there, among their cavalry, to give relief to their retreating troops, and sustain the impetuosity of our cavalry. Several of our soldiers were unexpectedly wounded by these, and left the battle. When the Gauls were confident that their countrymen were the conquerors in the action, and beheld our men hard pressed by numbers, both those who were hemmed in by the line of circumvallation and those who had come to aid them, supported the spirits of their men by shouts and yells from every quarter. As the action was carried on in sight of all, neither a brave nor cowardly act could be concealed; both the desire of praise and the fear of ignominy, urged on each party to valor. After fighting from noon almost to sunset, without victory inclining in favor of either, the Germans, on one side, made a charge against the enemy in a compact body, and drove them back; and, when they were put to flight, the archers were surrounded and cut to pieces. In other parts, likewise, our men pursued to the camp the retreating enemy, and did not give them an opportunity of rallying. But those who had come forth from Alesia returned into the town dejected and almost despairing of success.

The Gauls, after the interval of a day and after making, during that time, an immense number of hurdles, scaling-ladders, and iron hooks, silently went forth from the camp at midnight and approached the fortifications in the plain. Raising a shout suddenly, that by this intimation those who were beseiged in the town might learn their arrival, they began to cast down hurdles and dislodge our men from the rampart by slings, arrows, and stones, and executed the other movements which are requisite in storming. At the same time, Vercingetorix, having heard the shout, gives the signal to his troops by a trumpet, and leads them forth from the town. Our troops, as each man's post had been assigned him some days before, man the fortifications; they intimidate the Gauls by slings, large stones, stakes which they had placed along the works, and bullets. All view being prevented by the darkness, many wounds are received on both sides; several missiles, are thrown from the engines. But Marcus Antonius, and Caius Trebonius, the lieutenants, to whom the defense of these parts had been allotted, draughted troops from the redoubts which were more remote, and sent them to aid our troops, in whatever direction they understood that they were hard pressed.

While the Gauls were at a distance from the fortification, they did more execution, owing to the immense number of their weapons: after they came nearer, they either unawares empaled themselves on the spurs, or were pierced by the mural darts from the ramparts and towers, and thus perished. After receiving many wounds on all sides, and having forced no part of the works, when day drew nigh, fearing lest they should be surrounded by a sally made from the higher camp on the exposed flank, they retreated to their countrymen. But those within, while they bring forward those things which had been prepared by Vercingetorix for a sally, fill up the nearest trenches; having delayed a long time in executing these movements, they learned the retreat of their countrymen before they drew nigh to the fortifications. Thus they returned to the town without accomplishing their object.
