The American Volunteer Group was largely the creation of Claire L. Chennault, a retired U.S. Army Air Corps officer who had worked in China since August 1937, first as military aviation advisor to Generalissimo Chiang Kai-shek in the early months of the Sino-Japanese War, then as director of a Chinese Air Force flight school centered in Kunming. Meanwhile, the Soviet Union supplied fighter and bomber squadrons to China, but these units were mostly withdrawn by the summer of 1940. Chiang then asked for American combat aircraft and pilots, sending Chennault to Washington as an adviser to China's ambassador and Chiang's brother-in-law, T. V. Soong.
