"The Battle of Britain has been under the intense scrutiny of historians and others for half a century. Aided by hindsight, they have been able to raise various controversial issues. Criticism is all too easy for those who come after. To touch on but one issue, it is known that both sides overclaimed by a considerable amount. (The British claimed that they had destroyed 2,698 aircraft. The German claimed they they had shot down 3,058. Post war investigation proved that the RAF had actually shot down 1,733 German aircraft and that the Luftwaffe had shot down 915 British fighters.) No-one who has not experienced air fighting can possibly imagine the confusion. Neither can they judge. Relative scores are an effect, not a cause. What is clear is that the Battle of Britain was won by Fighter Command because it defeated the Luftwaffe in the battle to control the air over southern England. "
