de bello gallico, 5.39

And so with messengers immediately having been sent out to the Centrones, the Grudii, the Levaci, the Pleumoxii, and the Geidumni, who all are under their command, they gather as large bodies as they can, and dash unexpectedly to the winter-quarters of Cicero, the report of the death of Titurius not yet having been announced to him. It also occurred to him, which was necessary, that some (lit. not no) soldiers who had gone off into the woods for the sake of procuring timber and defensive material, were intercepted by the sudden arrival of the cavalry. With these having been surrounded by a great band, the Eburones, the Nervii, and the Aduatici and allies of all these and their dependents began to attack the legion. Our men quickly rally to arms; they mount the rampart. This day is scarcely endured, because the enemy placed all hope in speed, and, having gained this victory, they felt assured that they would be conquerors in perpetuity.
