14 August 1940, which Hitler code-named 'Adlertag', or 'Eagle Day', was fated to become one of the most significant days in the Battle of Britain. It signified the start of the Luftwaffe's aerial offensive, planned to cripple Britain and clear the path for the German troops ammased in readiness for invasion. The Luftwaffe sent out waves of unescorted bombers to attack targets by daylight, hoping to confuse the fighter defences with the small but numerous bomb formations. The tactic was a calculated gamble that cost the Germans deeply. Despite successes in attacking and damaging airfields, the losses were severe and and the following day Goering vetoed such tactics, now convinced his bombers could never operate over Britain without fighter cover. Using first-hand recollections of both Luftwaffe and RAF pilots as well as local witnesses to the day's action, gleaned from interviews and written accounts, author and researcher Hugh Trivett relays the events of notorious 'Eagle Day', as experienced by those who were actively involved. Using many unpublished photographs from his own collections as well as those contributors who dicussed their memories with him, Hugh Trivett has collated the definitive record of Eagle Day.
