Trotsky wanted the Communist Party to complete an orthodox proletarian revolution and have clear class independence from the KMT. Stalin funded the KMT during the expedition. Stalin countered Trotskyist criticism by making a secret speech in which he said that Chiang's right-wing Kuomintang were the only ones capable of defeating the imperialists, that Chiang Kai-shek had funding from the rich merchants, and that his forces were to be utilized until squeezed for all usefulness like a lemon before being discarded. However, Chiang quickly reversed the tables in the Shanghai massacre of 12 April 1927 by massacring the Communist Party in Shanghai midway through the Northern Expedition.
