[Q]: Passage: About 460, Roman diplomat and bishop Sidonius Apollinaris sent a letter to Riothamus asking his help to quell unrest among the Brettones, British colonists living in Armorica; this letter still survives. In the year 470, Western Emperor Anthemius began a campaign against Euric, king of the Visigoths who were campaigning outside their territory in Gaul. Anthemius requested help from Riothamus, and Jordanes writes that he crossed the ocean into Gaul with 12,000 soldiers. The location of Riothamus' army was betrayed to the Visigoths by Arvandus, the jealous praetorian prefect of Gaul, and Euric defeated him in the Battle of Déols after Riothamus army was driven from Avaricum (Bourges) where he had been welcomed by the Bituriges before the fight. Riothamus was last seen retreating northward to Burgundy when Euric besieged Arvernum (Clermont-Ferrand) just south of the Bituriges territory.
