C. Julius Caesar, Gallic War

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 mean time 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 dispatch of the Romans, send embassadors to Caesar respecting a surrender, and succeed in consequence of the Remi requesting that they [the Suessiones] might be spared.
