Hugely authoritative...brilliantly researched.’ Dan SnowBy summer of 1940, the Nazi Blitzkrieg had swept through much of western Europe, seizing control of territory right up to the Channel coast. A German invasion of Britain was expected to begin at any moment. But the key to success in such an invasion would be control of the skies over Britain – and the nation’s defenders were determined not to give in to their Nazi aggressors. The stage was set for one of the most important battles of the Second World War. This highly illustrated book, published in paperback, tells the heroic story of those five months using artefacts, interviews, documents, film, art and photographs from the archive at IWM. Personal testimony from those who were there helps bring to life this truly unique visual retelling of one of the most important moments of the Second World War.
