The Battle of Arles was fought between the Visigoths and the Western Roman Empire in 471. Prior to the battle, the Visigoths had advanced past the Bretons at the Battle of Déols in 469, and were expanding into Aquitaine. Alarmed with this development, Emperor Anthemius sent an expedition under Anthemiolus across the Alps against the Visigothic king Euric, who was besieging Arles.
