The Battle of Britain was the fourth of the US government's Why We Fight documentaries. The film uses newsreel footage and a few re-created scenes to illustrate the courage of the British people under the bombardment of Hitler's Luftwaffe. Much is made of the fact that Britain stood alone in 1940 when it was besieged by bombs, and that the little island was virtually the only Nazi target that refused to capitulate. The film concludes with scenes of the Royal Air Force preparing to pay Hitler back. Like the rest of the Why We Fight series, Battle of Britain was directed (or rather, assembled) by Frank Capra.
