10But Julian, being gratified at his increase of rank, and at the confidence of the soldiers in him, not to let his good fortune cool, or to give any colour for charging him with inactivity or indolence, after he had sent his envoys to Constantius, marched to the frontier of the province of lower Germany; and having with him all the force which the business in hand demanded, he approached the town of Santon.
2Then crossing the Rhine, he suddenly entered the district belonging to a Frank tribe, called the Attuarii, men of a turbulent character, who at that very moment were licentiously plundering the districts of Gaul. He attacked them unexpectedly while they were apprehensive of no hostile measures, but were reposing in fancied security, relying on the ruggedness and difficulty of the roads which led into their country, and which no prince within their recollection had ever penetrated. He, however, easily surmounted all difficulties, and having put many to the sword and taken many prisoners, he granted the survivors peace at their request, thinking such a course best for their neighbours.
3Then with equal celerity he repassed the river, and examining carefully the state of the garrisons on the frontier, and putting them in a proper state, he marched towards Basle; and having recovered the places which the barbarians had taken and still retained in their hands, and having carefully strengthened them, he went to Vienne, passing through Besançon, and there took up his winter quarters.
