The Roman History · Amm. 20.10.2

Then 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.
