In the biggest aerial engagement since the Battle of Britain, American, British and Canadian Spitfires fight it out with the Luftwaffe above the French coast near Dieppe on August 19th., 1942. A German 109 pilot parachutes from his stricken machine, risking a spectacular low level jump. Below, German armour can be seen moving to the beach, while on the horizon is the ill-fated combined Canadian/British landing at the town of Dieppe.
