Aecio
The army recruited for Flavius Aetius to combat Attila the Hun at the Battle of the Catalaunian Plains included Romans, Visigoths, Franks, Alans and Armoricans, amongst others. The Alans were placed front and centre, opposite the Huns. The Armoricans supplied archers who attacked the Huns' front lines during the main battle and thwarted Attila's night assault on the Roman camp with a hail of arrows "like rain". After the battle was won, Aetius sent the Alans to Armorica and Galicia.
