429 - At the request of Palladius, a British deacon, Pope Celestine I dispatches Bishops Germanus of Auxerre and Lupus of Troyes to Britain to combat Pelagian heresy. While in Britain, Germanus, a former military man, leads Celtic Britons to "Hallelujah" victory on the Welsh border.

446 - Celtic Britons (probably the pro-Roman party) appeal to Aetius, Roman governor of Gaul, for military assistance in their struggle against the Picts and the Irish/Scots. No help could be sent, at this time, as Aetius had his hands full with Attila the Hun.

Was this visit spiritually motivated, to combat a revived Pelagian threat or was Germanus sent in Aetius' stead, to do whatever he could to help the desperate Celtic Britons? Vortigern is accused of incest. Battle of Aylesford (Kent) in which the rebellious sons of Vortigern, Vortimer and Cadeyrn, defeat Hengest for the first time. Cadeyrn is killed in the fighting. Germanus expells the Irish from Powys (Mid Wales) and restores Cadeyrn's son, Cadell Ddernllwg, to the throne.
Circa 447 - Celtic Britons, aroused to heroic effort, "inflicted a massacre" on their enemies, the Picts and Irish, and were left in peace, for a brief time. Could this heroic effort have been led, again, by St. Germanus?

Reliable accounts by Sidonius Apolonaris and Jordanes name the leader of the 12,000 man Breton force, Riothamus.
