5.37
Sabinus orders tribunes of the soldier whom in the moment he was holding around him and the centurions of the first ranks to follow him and, when he had approached nearer to Ambiorix, having been commanded to hurl the weapons, does [the thing] ordered and he ordered his men to do the same. Meanwhile, while they discuss among themselves about the conditions/terms, and by plan a longer speech is begun by Ambiorix, gradually surrounded, he is killed.
Then indeed according to their custom they shout out “victory,” and they raise a howl, and with an attack made against our [men] they greatly disrupted [our] ranks. There Lucius Cotta while fighting is killed together with the greatest part of the soldiers. The remaining [men] withdraw into the camp from where they had marched out. From these Lucius Petrosidius the eagle-bearer, when he was overwhelmed by the great number of enemies, cast the eagle within the camp; he himself is slain while fighting most bravely in front of the camps.
With difficulty those [men] withstand the attack into the night; at night with safety despaired of, they all killed themselves to the man. A few [men] having slipped from the battle with uncertain passages come through the forests to the legate Titus Labienus in the winter quarters and they inform him of the events.
