XXXVII.--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 meantime, 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 entrenchments 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, make their way to Labienus at winter-quarters, after wandering at random through the woods, and inform him of these events. XXXVIII.--Elated by this victory, Ambiorix marches immediately with his cavalry to the Aduatuci, who bordered on his kingdom; he halts neither day nor night, and orders the infantry to follow him closely. Having related the exploit and roused the Aduatuci, the next day he arrived among the Nervii, and entreats "that they should not throw away the opportunity of liberating themselves for ever and of punishing the Romans for those wrongs which they had received from them"; [he tells them] "that two lieutenants have been slain, and that a large portion of the army has perished; that it was not a matter of difficulty for the legion which was wintering with Cicero to be cut off, when suddenly assaulted; he declares himself ready to co-operate in that design." He easily gains over the Nervii by this speech.
