The 2^nd Bombardment Squadron (“Avengers") of the 1^st Bombardment Group and the 28^th and 32^nd Fighter Squadrons of the 3^rd Fighter Group received movement orders on October 17, 1943, and became the Wing's first increment to move to China. They flew their planes over “the Hump”—the name given by Allied pilots to the eastern end of the Himalayan Mountains—to provide air support for Chiang Kai-shek's ground forces in accordance with Chennault's plan.
