The Battle of Britain was a fight for survival against a seemingly unstoppable foe. With the German army poised to invade, only the fighters of the Royal Air Force stood between Hitler and the conquest of Britain. Losses were high on both sides, but the Spitfires, Hurricanes, Havocs and Defiants of the RAF began to take their toll on the overextended, under-protected Kampfgruppen of Heinkel He 111s, Junkers Ju 87s and 88s, and Dornier Do 17s. Both sides learned and adapted as the campaign went on. As the advantage began to shift from the Luftwaffe to the RAF, the Germans were forced to switch from round-the-clock bombing to only launching night-raids, often hitting civilian targets in the dreaded Blitz. This beautifully illustrated study dissects the tactics and technology of the duels in this new kind of war, bringing the reader into the cockpits of the RAF fighters and Luftwaffe bombers to show precisely where the Battle of Britain was won and lost.
