Rival kingdoms and Pictish invasions cause civil war and famine in Britain; tensions between Pelagian and Roman factions aggravate the situation.

There is a migration of pro-Roman citizens towards Gaul.

It is possible that the “Groans of the Britons”, referring to a final Romano-British request for military assistance after the Roman departure from Britain, may have been addressed to Aegidius.

The appeal is first referenced in Gildas' sixth-century De Excidio et Conquestu Britanniae; Gildas' account is later repeated in Bede's Historia ecclesiastica gentis Anglorum.

The message according to Gildas was addressed to the general Flavius Aetius and requested his aid in defending formerly Roman Britain from the Picts and Scots.

The collapsing Western Roman Empire had few military resources to spare during the period referred to as the Decline of the Roman Empire and the record is ambiguous on what the response to the appeal was, if any.

The failure of the Roman armies to secure Britain according to Gildas and various later medieval sources led the Britons to invite Anglo-Saxon mercenaries to the island, precipitating the Anglo-Saxon invasion.
