The over -claiming by the Luftwaffe during the Battle of Britain was one part as to why they had to give up the fight, for those who think this wasnt the case I would sugest they read "The One Who Got Away", and pay close attention to the pilots " interview" during which the RAF interigator proved beyond a doubt that Von Wera, {the pilot in question} was a total bullslinger who like many other German pilots deserved the Pulitzer prize for fiction for his combat reports. Whilst training Luftwaffe students in Canada during the fifties many of them stated this fact in no uncertain terms. Later in the war, the night fighter arm was a model of acurate verified scores.
