 The large Hunno-German army captured several cities, and proceeded towards Aurelianum.Aetius, with the help of the influential Gallo-Roman senator Avitus, convinced the Visigoths of king Theodoric I to join him against the external menace; he also succeeded in persuading Sambida (who was falsely accused of planning to join the Huns), the Armoricans, the Salian Franks, some of the Saxons, and the Burgundians of Sapaudia to join his forces.Then the joint Roman and Visigothic army moved to relieve the besieged city of Aurelianum, forcing the Huns to abandon the siege and retreat to open country.
