The air war waged by the Luftwaffe agaon the RAF in the summer and autumn of 1940 was the key event of the World War II. If it had been lost, Hitler would have added the British Isles to his portfolio of subject nations. It was Churchill who coined the phrase 'Battle of Britain' to underscore the peril facing the nation and prepare it for the 'total war' that Hitler was about to unleash. During the campaign the British people were, in Winston Churchill's immortal words, 'sustained by unconquerable will-power'. The Battle of Britain presents in photographs the many aspects of this momentous campaign, from tactics, personalities, and aircraft to it's effect on the lives of civilians. Lavishly illustrated, it is a tribute to a nation which pulled together in the face of overwhelming odds and, united, saved and guided the world.
