C. Julius Caesar, Gallic War

Sabinus orders those tribunes of the soldiers whom he had at the time around him, and the centurions of the first ranks, to follow him, and when he had approached near to Ambiorix, being ordered to throw down his arms, he obeys the order and commands his men to do the same. In the mean time, while they treat upon the terms, and a longer debate than necessary is designedly entered into by Ambiorix, being surrounded by degrees, he is slain. Then they, according to their custom, shout out "Victory," and raise their war-cry, and, making an attack on our men, break their ranks. There L. Cotta, while fighting, is slain, together with the greater part of the soldiers; the rest betake themselves to the camp, from which they had marched forth, and one of them, L. Petrosidius, the standard bearer, when he was overpowered by the great number of the enemy, threw the eagle within the intrenchments and is himself slain while fighting with the greatest courage before the camp. They with difficulty sustain the attack till night; despairing of safety, they all to a man destroy themselves in the night. A few escaping from the battle, made their way to Labienus at winter-quarters, after wandering at random through the woods, and inform him of these events
