The real King Arthur. After the Roman soldiers left in AD410, Britain no longer had a strong army to defend it. There were battles between Anglo-Saxons and Britons. In AD491, for instance, a fight for the Roman fort at Pevensey in Sussex was won by the Anglo-Saxons, who killed all the Britons in the fort.ne group of Anglo-Saxon invaders were called the Haestingas. They gave their name to the seaside town of Hastings. Stories about King Arthur crop up all over Britain-in Wales, Cornwall, in the west of England and as far north as Scotland.
