A series of missed airstrikes resulting in the death of civilians sparked the no-holds-barred Battle of Britain. Germany launched a Blitz to bomb London into submission, but inadvertantly sparked more resistance and gave British industry a chance to bounce back. On August 25, 1940, a group of German bomber planes got lost on a night-time mission over England. They wound up dropping bombs not on their industrial target, but on the city of London itself. Winston Churchill ordered a retaliatory strike against Germany, but this time it was the RAF who missed their target and hit civilians. Hitler was convinced this was intentional, so he rescinded his prohibition against targeting civilians. The Luftwaffe organized a massive attack against London, intending to break the British people's will to fight. The Blitz backfired in several respects. First, it diverted Germany's attention from strategic targets, which meant they were no longer putting real pressure on the British industrial war efforts. Second, they wound up bringing the British together and strengthening their will to fight on in the names of those who'd been lost to German bombs. Ultimately, the cost in men and material for Germany to wage the Battle of Britain exceeded the cost of damage they inflicted.
