In the summer of 1940, the Nazi Blitzkrieg had blown through much of western Europe, seizing control of territory right up to the French coast and preparing to invade Britain. Standing in their way was Fighter, Bomber, and Coastal Commands and the Royal Navy, all determined to prevent invasion, fighting off enemy forces in the air and in the water to protect the British shores. Published to coincide with Battle of Britain Day in 2022, this illustrated book tells the heroic story of those five months using artifacts, interviews, documents, film, art, and photographs from the vast Imperial War Museums archives. Personal testimony from those who were there helps bring to life this unique visual retelling of one of the most important moments of World War II.
