XI.--That matter being determined on, marching out of their camp at the second watch, with great noise and confusion, in no fixed order, nor under any command, since each sought for himself the foremost place in the journey, and hastened to reach home, they made their departure appear very like a flight. Caesar, immediately learning this through his scouts, [but] fearing an ambuscade, because he had not yet discovered for what reason they were departing, kept his army and cavalry within the camp. At daybreak, the intelligence having been confirmed by the scouts, he sent forward his cavalry to harass their rear; and gave the command of it to two of his lieutenants, Q. Pedius, and L. Aurunculeius Cotta. He ordered T. Labienus, another of his lieutenants, to follow them closely with three legions. These, attacking their rear, and pursuing them for many miles, slew a great number of them as they were fleeing; while those in the rear with whom they had come up, halted, and bravely sustained the attack of our soldiers; the van, because they appeared to be removed from danger, and were not restrained by any necessity or command, as soon as the noise was heard, broke their ranks, and, to a man, rested their safety in flight. Thus without any risk [to themselves] our men killed as great a number of them as the length of the day allowed; and at sunset desisted from the pursuit, and betook themselves into the camp, as they had been commanded. XII.--On the day following, before the enemy could recover from their terror and flight, Caesar led his army into the territories of the Suessiones, which are next to the Remi, and having accomplished a long march, hastens to the town named Noviodunum. Having attempted to take it by storm on his march, because he heard that it was destitute of [sufficient] defenders, he was not able to carry it by assault, on account of the breadth of the ditch and the height of the wall, though few were defending it. Therefore, having fortified the camp, he began to bring up the vineae, and to provide whatever things were necessary for the storm. In the meantime, the whole body of the Suessiones, after their flight, came the next night into the town. The vineae having been quickly brought up against the town, a mound thrown up, and towers built, the Gauls, amazed by the greatness of the works, such as they had neither seen nor heard of before, and struck, also, by the despatch of the Romans, send ambassadors to Caesar respecting a surrender, and succeed in consequence of the Remi requesting that they [the Suessiones] might be spared.
