460 CE to 471 CE
The Britons, pressured by the continental invaders who have established a beachhead in Kent, begin moving westward.
Many thousands of Britons immigrate across the Channel to Armorica (present Brittany).
A union of Britons, occurring in about 470, helps to bring about a cessation of hostilities.
The collapse of Roman power and the depredations of the Visigoths led Armorica, according to C.E.V.Nixon, to act "like a magnet to peasants, coloni, slaves and the hard-pressed" who deserted other Roman territories, further weakening them.
