The Battle of Britain (4): the hardest day
At the time, 18 August 1940 – 70 years ago today – was seen as the toughest day of the Battle of Britain and a turning point in the fortunes of the Royal Air Force. In reality, the intensity of air activity was greater on 15 and 16 August 1940 and the number of Fighter Command aircraft in combat was greater on at least half a dozen other days.
