Huaihai Campaign
After the war, Nanking was once again the capital of the Republic of China, though now the Chinese Civil War had broken out between the Kuomintang government and Communist forces, based further north, mostly in Northeast China. The decisive Huaihai Campaign was fought in northern Jiangsu; it resulted in Kuomintang defeat, and the communists were soon able to cross the Yangtze River and take Nanking. The Kuomintang fled southward and eventually ended up in Taipei, from which the Republic of China government continues to administer Taiwan, Pescadores, and its neighboring islands, though it also continues to claim (technically, at least) Nanjing as its rightful "de jure" capital.
