I want to know the answer to the following question:
Who led the rescue of British forces during the Battle of Yenangyaung?
All the background I'm provided with is that "Cooperation between the Chinese Nationalists and the Communists had waned from its zenith at the Battle of Wuhan, and the relationship between the two had gone sour as both attempted to expand their area of operations in occupied territories.". Is that enough to answer the question?
