C. Julius Caesar, Gallic War

The camp-followers run forward to the nearest rising ground; being speedily driven from this they throw themselves among the standards and companies: they thus so much the more alarm the soldiers already affrighted. Some propose that, forming a wedge, they suddenly break through, since the camp was so near; and if any part should be surrounded and slain, they fully trust that at least the rest may be saved; others, that they take their stand on an eminence, and all undergo the same destiny. The veteran soldiers whom we stated to have set out together [with the others] under a standard, do not approve of this. Therefore encouraging each other, under the conduct of Caius Trebonius, a Roman knight, who had been appointed over them, they break through the midst of the enemy, and arrive in the camp safe to a man. The camp attendants and the horse following close upon them with the same impetuosity, are saved by the courage of the soldiers. But those who had taken their stand upon the eminence having even now acquired no experience of military matters, neither could persevere in that resolution which they approved of, namely, to defend themselves from their higher position, nor imitate that vigor and speed which they had observed to have availed others; but, attempting to reach the camp, had descended into an unfavorable situation. The centurions, some of whom had been promoted for their valor from the lower ranks of other legions to higher ranks in this legion, in order that they might not forfeit their glory for military exploits previously acquired, fell together fighting most valiantly. The enemy having been dislodged by their valor, a part of the soldiers arrived safe in camp contrary to their expectations; a part perished, surrounded by the barbarians.
