Group Captain Peter Townsend - himself a Battle of Britain pilot - traces the background to the conflict from the defeat and destruction of the Kaiser's air force to the long days of 1940 when Spitfires and Messerschmitts fought their battles to the death over England. Dogfights in the sky, ruthless political manoeuvres, legendary heroes of the air like Richthofen (the 'Red Baron') and Douglas Bader - Duel of Eagles combines all of these in a colourful, dramatic and evocative account of the furious air conflict that saved Britain from German invasion.
