12. Nor indeed was he contented with this, but he also collected provisions for himself and his army sufficient for twenty days. For the soldiers delighted in using the food which they had won with their own right hands, being especially indignant because, out of all the supplies which had been recently sent them, they were not able to obtain anything, inasmuch as Barbatio, when they were passing near his camp, had with great insolence seized on a portion of them, and had collected all the rest into a heap and burnt them. Whether he acted thus out of his own vanity and insane folly, or whether others were really the authors of this wickedness, relying on the command of the emperor himself, has never been known. 13. However, as far as report went, the story commonly was, that Julian had been elected Cæsar, not for the object of relieving the distresses of the Gauls, but rather of being himself destroyed by the formidable wars in which he was sure to be involved; being at that time, as was supposed, inexperienced in war, and not likely to endure even the sound of arms. 14. While the works of the camp were steadily rising, and while a portion of the army was being distributed among the stations in the country districts, Julian occupied himself in other quarters with collecting supplies, operating with great caution, from the fear of ambuscades. And in the mean time, a vast host of the barbarians, outstripping all report of their approach by the celerity of their movements, came down with a sudden attack upon Barbatio, and the army which (as I have already mentioned) he had under his command, separated from the Gallic army of Severus only by a rampart; and having put him to flight, pursued him as far as Augst, and beyond that town too, as far as they could; and, having made booty of the greater part of his baggage and beasts of burden, and having carried off many of the sutlers as prisoners, they returned to their main army. 15. And Barbatio, as if he had brought his expectations to a prosperous issue, now distributed his soldiers into winter quarters, and returned to the emperor's court, to forge new accusations against the Cæsar, according to his custom. XII. § 1. When this disgraceful disaster had become known, Chnodomarius and Vestralpus, the kings of the Allemanni, and Urius and Ursicinus, with Serapion, and Suomarius, and Hortarius, having collected all their forces into one body, encamped near the city of Strasburg, thinking that the Cæsar, from fear of imminent danger, had retreated at the very time that he was wholly occupied with completing a fortress to enable him to make a permanent stand.
