After losing the Battle of Britain, the German Luftwaffe switched to night bombing raids in an attempt to defeat British morale. This study examines the causes, effects and outcome of the raids on the civilian population of Britain in 1940-41. The author discusses the German decision to switch to night attacks, their weapons and tactics, the poor initial British defences, and the reactions of the civilian population to the prolonged bombing raids. He also attempts to assess the responsibility for the breach of British defences. He discusses the removal of the commander responsible for defence, political responses, and the effects of the raids on war production. Lastly, the book deals with the retaliation by Bomber Command, and the final attacks.
