'British Battles 493–937' is one of the most revolutionary books ever published on war in Britain. It deals with thirteen conflicts, either locating them correctly or explaining some of their aspects which have puzzled historians. They include the following: Mount Badon (493) at Braydon, Wiltshire; battles of the British hero Arthur (the legendary 'King Arthur') (536–7) in southern Scotland or the borders; 'Degsastan' (603) at Dawyck, on the River Tweed, Scotland; Maserfelth (642) at Forden, on the Welsh border; the Viking victory of 'Alluthèlia' (844) at Bishop Auckland, near Durham; and the English triumph of Brunanburh (937) was at Lanchester, also near Durham.
