Luftwaffe aces explain their tactics and relate their experiences during the bloody campaign known as the Defence of the Reich. Their missions changed from waiting for the short-range Allied fighter escorts to turn back before attacking the bomber formations, to see-saw battles for aerial supremacy against long-range P-51s defending US heavy bomber streams. The story - based on personal accounts and official records from both sides - is predominantly that of the Bf 109's struggle to defeat the US Eighth Air Force (although latterly both the 'mediums' of the US Ninth Air Force and the 'heavies' of RAF Bomber Command were also active by day over Germany).
