The Battle of Argentovaria or Battle of Argentaria was fought in May 378 between the Western Roman Empire and the invading army of the Lentienses, a branch of the Alemanni, at Argentovaria (near Colmar, France). The Alemanni were overwhelmed by the Roman legionaries, though stood their ground bravely. Only 9,000 escaped from the field and Priarius, king of the Lentienses, was slain during the battle.
