After France collapses in 1940, Britain stands as the only major power still resisting Nazi Germany, and this film covers the months that followed. Dogfights over the English Channel escalate into the Battle of Britain, as RAF pilots scramble against Luftwaffe formations trying to clear the skies for a German invasion that never comes. The Blitz brings the war to London and other cities, with archival footage of bombed streets, shelters, and civilians carrying on under nightly air raids. Away from the Channel, the conflict widens as Italian troops push into North Africa, opening a second front that will draw in British forces defending Egypt and the Suez Canal. Drawing on period footage, maps, and expert commentary, the film traces how Churchill's government held together through a year when defeat looked plausible, and how the fighting in the air and in the desert set the terms for the rest of the war. It is part of the Price of Empire series on Timeline.
