C. Julius Caesar, Gallic War

In the mean time Caius Caninius, a lieutenant, having received information by letters and messages from Duracius, who had always continued in friendship to the Roman people, though a part of his state had revolted, that a great multitude of the enemy were in arms in the country of the Pictones, marched to the town Limonum . When he was approaching it, he was informed by some prisoners, that Duracius was shut up by several thousand men, under the command of Dumnacus, general of the Andes, and that Limonum was besieged, but not daring to face the enemy with his weak legions, he encamped in a strong position: Dumnacus, having notice of Caninius's approach, turned his whole force against the legions, and prepared to assault the Roman camp. But after spending several days in the attempt, and losing a considerable number of men, without being able to make a breach in any part of the works, he returned again to the siege of Limonum .
