Gallic War (7.59-7.62)

Caesar was now reported to have departed from Gergovia ; intelligence was likewise brought to them concerning the revolt of the Aedui, and a successful rising in Gaul; and that Caesar, having been prevented from prosecuting his journey and crossing the Loire , and having been compelled by the want of corn, had marched hastily to the province. But the Bellovaci, who had been previously disaffected of themselves, on learning the revolt of the Aedui, began to assemble forces and openly to prepare for war. Then Labienus, as the change in affairs was so great, thought that he must adopt a very different system from what he had previously intended, and he did not now think of making any new acquisitions, or of provoking the enemy to an action; but that he might bring back his army safe to Agendicum. For, on one side, the Bellovaci, a state which held the highest reputation for prowess in Gaul, were pressing on him; and Camulogenus, with a disciplined and well-equipped army, held the other side; moreover, a very great river separated and cut off the legions from the garrison and baggage. He saw that, in consequence of such great difficulties being thrown in his way, he must seek aid from his own energy of disposition.

Having, therefore, called a council of war a little before evening, he exhorted his soldiers to execute with diligence and energy such commands as he should give; he assigns the ships which he had brought from Melodunum to Roman knights, one to each, and orders them to fall down the river silently for four miles, at the end of the fourth watch, and there wait for him. He leaves the five cohorts, which he considered to be the most steady in action, to guard the camp; he orders the five remaining cohorts of the same legion to proceed a little after midnight up the river with all their baggage, in a great tumult. He collects also some small boats; and sends them in the same direction, with orders to make a loud noise in rowing. He himself, a little after, marched out in silence, and, at the head of three legions, seeks that place to which he had ordered the ships to be brought.

When he had arrived there, the enemy's scouts, as they were stationed along every part of the river, not expecting an attack, because a great storm had suddenly arisen, were surprised by our soldiers: the infantry and cavalry are quickly transported, under the superintendence of the Roman knights, whom he had appointed to that office. Almost at the same time, a little before daylight, intelligence was given to the enemy that there was an unusual tumult in the camp of the Romans, and that a strong force was marching up the river, and that the sound of oars was distinctly heard in the same quarter, and that soldiers were being conveyed across in ships a little below. On hearing these things, because they were of opinion that the legions were passing in three different places, and that the entire army, being terrified by the revolt of the Aedui, were preparing for flight, they divided their forces also into three divisions. For leaving a guard opposite to the camp and sending a small body in the direction of Metiosedum, with orders to advance as far as the ships would proceed, they led the rest of their troops against Labienus.

By day-break all our soldiers were brought across, and the army of the enemy was in sight. Labienus, having encouraged his soldiers "to retain the memory of their ancient valor, and so many most successful actions, and imagine Caesar himself, under whose command they had so often routed the enemy, to be present," gives the signal for action. At the first onset the enemy are beaten and put to flight in the right wing, where the seventh legion stood: on the left wing, which position the twelfth legion held, although the first ranks fell transfixed by the javelins of the Romans, yet the rest resisted most bravely; nor did any one of them show the slightest intention of flying. Camulogenus, the general of the enemy, was present and encouraged his troops. But when the issue of the victory was still uncertain, and the circumstances which were taking place on the left wing were announced to the tribunes of the seventh legion, they faced about their legion to the enemy's rear and attacked it: not even then did any one retreat, but all were surrounded and slain. Camulogenus met the same fate. But those who were left as a guard opposite the camp of Labienus, when they heard that the battle was commenced, marched to aid their countrymen and take possession of a hill, but were unable to withstand the attack of the victorious soldiers. In this manner, mixed with their own fugitives, such as the woods and mountains did not shelter were cut to pieces by our cavalry. When this battle was finished, Labienus returns to Agendicum, where the baggage of the whole army had been left: from it he marched with all his forces to Caesar.
