"Stillwell constantly complained "
Yes, he certainly did, when he wasn't putting broomsticks in Chennault's spokes. Yadada yadada yadada, shut the hell up, Vinegar Joe.
Chiang tried to get rid of him from almost the day he arrived.
Have you read "The Flying Tiger," by Jack Samson?
I do not mean to run down the Flying Tigers or those Chinese troops that fought alongside Merril's Maruaders at Mytchkina (sp?), for example. All I'm saying is that lives and treasure were expended (opening the Ledo Road, Flying the Hump, Keeping the 14th Air Force supplied, etc)on a scale that far outweighed the Chinese contribution to the overall fighting.
China served best as a magnet for Japanese troops and materiel that would have gone elsewhere.
Chiang played Roosevelt like a fiddle, getting the money, supplies and other aid that he artfully avaoided using against the Japsanese. He instead used it against the Commies, and look where it got him? The fact is that the Chinese Army was rife with corruption, staffed by political cronies and ineffective officers and served mainly by standing in front of the Japanese who had to station troops to merely watch them.
Over 2 million Japanese troops were still in China in August of 1945. No Chinese troops were in Japan, or anyplace else for that matter.
