Seventy years ago the battle was at its height over southern England.
On 15 September two massive waves of German attacks were decisively repulsed by the RAF, with every aircraft of 11 Group being used on that day. The total casualties on this critical day were 60 German and 26 RAF aircraft shot down. The German defeat caused Hitler to order, two days later, the postponement of preparations for the invasion of Britain. Henceforth, in the face of mounting losses in men, aircraft and the lack of adequate replacements, the Luftwaffe switched from daylight to night-time bombing.
