probably increased during the Anglo-Saxon invasion of Britain in the 5th and 6th centuries. Scholars such as Léon Fleuriot have suggested a two-wave model of migration from Britain which saw the emergence of an independent Breton people and established the dominance of the Brythonic Breton language in Armorica. Their petty kingdoms are now known by the names of the counties that succeeded them—Domnonée (Devon), Cornouaille (Cornwall), Léon (Caerleon); but these names in Breton and Latin are in most cases identical to their British homelands. (In Breton and French, however, Gwened or Vannetais continued the name of the indigenous Veneti.) Although the details remain confused, these colonies consisted of related and intermarried dynasties which repeatedly unified (as by the 7th-century Saint Judicaël) before splintering again according to Celtic inheritance practices. Resistance The area was finally consolidated in the 840s under Nominoe in resistance to Frankish control. Among the immigrant Britons, there were some clergymen who helped the evangelisation of the region, which was still pagan, particularly in rural areas. Battle of the Catalaunian Plains 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. Riothamus The late 5th century Brittonic leader Riothamus received correspondence from the eminent Roman jurist Sidonius Apollinaris and was called "King of the Britons" by Jordanes. Some suggest that he was a Breton, though others believe that he was from Britain, pointing to the passage that he arrived in the land of the Biturges "by way of Ocean", which would hardly have been efficient or required for a Breton. Both historians describe Riothamus's losing battle against King Euric of the Visigoths at Déols around the year 470. In response to a plea from the Roman Emperor Anthemius, Riothamus had led twelve thousand men to establish a military presence in Bourges in central Gaul, but was betrayed by Arvandus, the Praetorian Prefect of Gaul, and subsequently ambushed by Euric's army. After a long battle, the Armorican survivors escaped to Avallon in Burgundy, after which they are lost to
