The most famous invasion of the Alemanni occurred at Strasbourg on the Rhine. Not only did Emperor Julian rout the invaders, but the Alemanni chieftain Chnodomer was captured and taken to Rome. Only ten years later, however, the invaders crossed the ice during the winter and poured into Gaul. The battle of Solicinium was hard fought with heavy losses on both sides, but again, the barbarians were driven back. The last time the Romans resisted the incursions of an Alemmani tribe was in 378 A.D., when the Emperor Gratian met a tribe of Lentienses at the battle of Argentaria, and drove them back across the Rhine. Soon after this, Hunnic invasions in the east caused an enormous stir within central Europe, and forced irrepressible migrations that would soon collapse the western empire. In about 406 A.D., when the Western empire was already suffering for Gothic invasions from the east, the integrity of the Western borders broke down altogether. In about 406 A.D., the Alemanni were part of a massive migration of Germans into Roman territory. They are thought to have settled somewhere around Alsace, and became part of the Frankish Empire.
