Gallic War (6.39-6.42)

The foraging having in the mean time been completed, our soldiers distinctly hear the shout; the horse hasten on before and discover in what danger the affair is. But here there is no fortification to receive them, in their alarm: those last enlisted, and unskilled in military discipline turn their faces to the military tribune and the centurions; they wait to find what orders may be given by them. No one is so courageous as not to be disconcerted by the suddenness of the affair. The barbarians, espying our standard in the distance, desist from the attack; at first they suppose that the legions, which they had learned from their prisoners had removed further off, had returned; afterward, despising their small number, they make an attack on them at all sides.

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.

The Germans, despairing of taking the camp by storm, because they saw that our men had taken up their position on the fortifications, retreated beyond the Rhine with that plunder which they had deposited in the woods. And so great was the alarm, even after the departure of the enemy, that when C. Volusenus, who had been sent with the cavalry, arrived that night, he could not gain credence that Caesar was close at hand with his army safe. Fear had so pre-occupied the minds of all, that their reason being almost estranged, they said that all the other forces having been cut off, the cavalry alone had arrived there by flight, and asserted that, if the army were safe, the Germans would not have attacked the camp; which fear the arrival of Caesar removed.

He, on his return, being well aware of the casualties of war, complained of one thing [only], namely, that the cohorts had been sent away from the outposts and garrison [duty], and pointed out that room ought not to have been left for even the most trivial casualty; that fortune had exercised great influence in the sudden arrival of their enemy; much greater, in that she had turned the barbarians away from the very rampart and gates of the camp. Of all which events, it seemed the most surprising, that the Germans, who had crossed the Rhine with this object, that they might plunder the territories of Ambiorix, being led to the camp of the Romans, rendered Ambiorix a most acceptable service.
