This led to destruction of the Nationalist army and government in China, establishing Communist rule on the mainland and Nationalist rule on Formosa (Taiwan)." [Davis: 100 Decisive Battles, p. 415] "Huaihai Campaign or Battle of Hsupeng was one of the military conflicts in the late stage of the Chinese Civil War between the Kuomintang and the Chinese Communist Party. The campaign started when the People's Liberation Army (PLA) launched a major offensive against the Kuomintang headquarter in Xuzhou on 6 November 1948, and ended on 10 January 1949 when the PLA reached the north of the Yangtze."
