 The 14th Air Force was involved in strafing and bombing attacks against the Japanese advancing on the city of Changsha, which Japanese had tried and failed to take three previous times since 1938, making the city into a symbol of Chinese defiance.Relations between Stilwell and Chennault reached their low point in 1944.Stilwell used the success of Operation Ichigo as proof the fallacy of Chennault's claim that air power alone could defeat Japan while Chennault accused of Stilwell of deliberately taking a defeatist attitude as a gambit to force Chiang to cede more powers of command to him.
