Battle of Bedegraine

The battle of Arthur's final victory over the rebel kings. 
Though his force is outnumbered by King Lot, Arthur carries the day with the aid of the French kings Ban and Bors. The rebel kings were forced to then retreat to their own territory in order to fend off Saxon invaders, and eventually recognize Arthur as their rightful overlord.
The lands of Bedegraine are located to the north of Camelot, east of the mountains, in the lands later considered South Rheged. Bedegraine is the home of King Leodegrance and his daughter Guinevere.
