According to the history written by a monk named Nennius in the ninth century the legendary King Arthur was a successful military leader who fought several battles during the troubled times of the 530’s , being ultimately killed at Camlan in 537. He is thought by many historians to be based on an amalgamation of different leaders from the sub-Roman dark age period. According to Nennius he operated in southern Scotland and the north of England with his base being in the Welsh Kingdom of Strathclyde. From here he fought several opponents , not just the Anglo-Saxons of legends but also other Welsh and Pictish enemies. Most historians agree that he was Romanised being from the allied Welsh kingdoms of the Romans adjacent to Hadrian’s Wall. As such he would have been Christian, trained in Roman cavalry tactics and equipped like Roman auxiliary cavalry.
