The Germanic confederation of the Alemanni attempted to cross the Rhine several times in the 4th century, but were repelled; one such event was the Battle of Solicinium (368). However, in the great invasion of AD 406, the Alemanni appear to have crossed the Rhine a final time, conquering and then settling what is today Alsace and a large part of the Swiss Plateau.
