C. Julius Caesar, Gallic War

At this very time, the German horse by chance came up, and immediately, with the same speed with which they had advanced, attempt to force the camp at the Decuman gate, nor were they seen, in consequence of woods lying in the way on that side, before they were just reaching the camp: so much so, that the sutlers who had their booths under the rampart had not an opportunity of retreating within the camp. Our men, not anticipating it, are perplexed by the sudden affair, and the cohort on the outpost scarcely sustains the first attack. The enemy spread themselves on the other sides to ascertain if they could find any access. Our men with difficulty defend the gates; the very position of itself and the fortification secures the other accesses. There is a panic in the entire camp, and one inquires of another the cause of the confusion, nor do they readily determine whither the standards should be borne, nor into what quarter each should betake himself. One avows that the camp is already taken, another maintains that, the enemy having destroyed the army and commander-in-chief, are come hither as conquerors; most form strange superstitious fancies from the spot, and place before their eyes the catastrophe of Cotta and Titurius, who had fallen in the same fort. All being greatly disconcerted by this alarm, the belief of the barbarians is strengthened that there is no garrison within, as they had heard from their prisoner. They endeavor to force an entrance and encourage one another not to cast from their hands so valuable a prize.
