September 1940 marked a shift in Germany’s aerial war against Britain. What was based on tactical strikes against airfields and radar stations in order to prepare for an invasion changed to wide-scale bombing of London with the aim of forcing surrender.
The extent of destruction wrought by Germany’s bombs no doubt inspired reprisals later in the war, such intense bombing raids carried out by the British and Allied forces on civilian targets in Germany.
Here are 10 facts about both the German Blitzkrieg and the Allied bombing of Germany.
1. 55,000 British civilian casualties were sustained through German bombing before the end of 1940
This included 23,000 deaths.
2. London was bombed for 57 consecutive nights from 7 September 1940
