Prior to the United States' entry into WWII many Americans volunteered for service in the RAF and RCAF. The Battle of Britain raged from May though October 1940. The stories of the RAF pilots flying their Hurricanes and Spitfires inspired many to look into joining the RAF. Of the thousands that volunteered, 244 American pilots were to fly for the Eagle Squadrons; Number 71, 121, and 133 Squadrons of the Royal Air Force Fighter Command. From the time the first Eagle Squadron was formed in September 1940 until all three squadrons were disbanded and incorporated into the USAAF in September 1942, they destroyed 73 German planes while 77 American and 5 British members were killed. On 29 September 1942 the Eagle Squadrons were incorporated into the Fourth Fighter Group, USAAF as the 334th(71), 335th(121), and 336th(133). Had you known many Americans crossed the border into Canada to start their training with the Royal Airforce and Canadian Royal Airforce?
