Du Yuming
In September 1945 Peng was sent by Mao Zedong to take up overall leadership of the Communists in Northeast China. He was accompanied by Lin Biao who was to assist Peng with directing military operations against the Nationalists. Peng decided that the Communists could hold the 3 big cities of the Northeast: Shenyang, Changchun and Harbin. When the Nationalists under the command of Du Yuming attacked in November 1945, the Communists were forced back. Peng was removed as Communist leader in the northeast after further failure by Lin Biao's forces in March 1946 led to the Communists retreat back to Harbin.
