The Arthur Leader in the History of the Dark Age

The figure spoken of and written of as arthur, this formidable british warrior leader, might have been exactly the person that we're looking for. It is actually conceivable that a leader could have taken advantage of two assets effectively against the anglo saxons. One is horses and superior horsemanship, which might have been inherited from the roman age and roman cavalry. And understanding of the landscape, clearly, the roman road system, which still would have existed in the fifth and sixth centuries. This seems to account for this otherwise strange political and military course of events.
