C. Julius Caesar, Gallic War

Caesar, being apprized of this by Titurius, leads all his cavalry and light-armed Numidians, slingers and archers, over the bridge, and hastens toward them. There was a severe struggle in that place. Our men, attacking in the river the disordered enemy, slew a great part of them. By the immense number of their missiles they drove back the rest, who, in a most courageous manner were attempting to pass over their bodies, and surrounded with their cavalry, and cut to pieces those who had first crossed the river. The enemy, when they perceived that their hopes had deceived them both with regard to their taking the town by storm and also their passing the river, and did not see our men advance to a more disadvantageous place for the purpose of fighting, and when provisions began to fail them, having called a council, determined that it was best for each to return to his country, and resolved to assemble from all quarters to defend those into whose territories the Romans should first march an army; that they might contend in their own rather than in a foreign country, and might enjoy the stores of provision which they possessed at home. Together with other causes, this consideration also led them to that resolution, viz: that they had learned that Divitiacus and the Aedui were approaching the territories of the Bellovaci. And it was impossible to persuade the latter to stay any longer, or to deter them from conveying succor to their own people.
