de bello gallico, 5.26

Around the fifteenth day in which it was come into winter quarters, the start of a sudden tumult and defection was begun by Ambiorix and Catuvolcus; who, although they had met Sabinus and Cotta at the borders of their own kingdom and they had carried grain into the winter quarter, influenced by messages of the Treverus Indutiomarus they roused their own men and, with those who collect firewood having been attacked suddenly by a large band, they came to attack to the camp. When our men quickly had seized arms and had ascended the rampart and with the Spanish cavalry having been sent out from one side they had been superior in a cavalry battle, with the matter having been given up, the enemy lead their own men back from the attack. Then by their custom they shouted that some of our men go should forth to a meeting: they had things which they wanted to say about a joint matter, by which things they hoped to be able to abate the dispute.
