As a result of the split between the Communists and the Kuomintang at Wuhan in July 1927, the Nationalists managed to set up a unified régime of their own at Nanking. But T'ang Sheng-chih, the KMT military leader at Wuhan, rebelled against that unified régime. So Nanking decided to send troops to fight him on October 24. This KMT civil strife led immediately to an intra-Party power struggle among the Communists who had been forced underground since July. The Communist struggle took the form of a dispute over a proposed insurrection at Wuhan in the event of T'ang Sheng-chih's defeat.
