Effect of English Conquest on Britons.

Many of Britons were killed in the fighting. Many of them took refuge in the West in Cornwall, Wales and Cumberland. Some went over the sea to the north west of France and settled in the land called Brittany. To the English Britons were known as Welsh. Cornishmen were West Welsh, the people of Wales were North Welsh and those of Cumberland were Cumbrian Welsh. Until the West Saxons won the Battle of Deorham in 577, the West Welsh were not cut off from the North Welsh. Similarly, North Welsh was cut off from the Cumbrian Welsh when the Angels won the Battle of Chester in 613 and reached the Irish Sea.
