One of the first recorded battles between the Anglo-Saxons and those who would later settle in Wales was the Battle of Crayford. The Anglo-Saxon Chronicle wrote:
A.D. 456. This year Hengest and Aesc his son fought with the Britons on the spot that is called Crayford, and there slew 4000 men, and the Britons then left the land of Kent, and in great fear fled to London.
About 10 years later, the Britons had a victory against Hengist and his son at Wippidsfleet, but the Anglo-Saxons regained ground in Kent. They ultimately captured the castle of Anderida on the Saxon Shore (south coast) and the leader Aelle established the kingdom of Sussex ("South Saxon"). This was in 491 according to the Anglo-Saxon Chronicle, but historians think it took place in 471. Another Anglo-Saxon, Cerdic, established the kingdom of Wessex ("West Saxons") after driving Britons away from the Bournemouth area.
It is around this time that the legends of Arthur, King of the Britons, gain popularity. He is a leader who opposes (successfully) the Anglo-Saxon invaders. The Historia Brittonum ("History of the Britons") by Nennius (borrowing from Bede, and Gildas' De Excidio et Conquestu Britanniae, "On the Ruin and Conquest of Britain") lists several battles, none of which can be historically proven.
Over the centuries, it is no exageration to say that scores of battles—and probably hundreds, counting skirmishes too small to gain the attention of contemporary chroniclers—took place between Britons and the invaders. Until, that is, a kind of peace was managed by a Welsh leader powerful enough to unite the various kingdoms of Wales and form an alliance with the kingdom of Wessex. That was Hywel Dda ("Howel the Good"), and I'll tell you about him tomorrow.
