Peng Dehuai was a Chinese general and China's Minister of National Defense from 1954 to 1959. Peng was born into a poor peasant family, and received several years of primary education before his family's poverty forced him to suspend his education at the age of ten, and to work for several years as a manual laborer. When he was sixteen, Peng became a professional soldier. Over the next ten years Peng served in the armies of several Hunan-based warlord armies, raising himself from the rank of private second class to major. In 1926, Peng's forces joined the Kuomintang, and Peng was first introduced to communism. Peng participated in the Northern Expedition, and supported Wang Jingwei's attempt to form a left-leaning Kuomintang government based in Wuhan. After Wang was defeated, Peng briefly rejoined Chiang Kai-shek's forces before joining the Chinese Communist Party (CCP), allying himself with Mao Zedong and Zhu De.

Lin Biao was a Chinese politician and Marshal of the People's Republic of China who was pivotal in the Communist victory during the Chinese Civil War, especially in Northeast China from 1946 to 1949. Lin was the general who commanded the decisive Liaoshen and Pingjin campaigns, in which he co-led the Manchurian Field Army to victory and led the People's Liberation Army into Beijing. He crossed the Yangtze River in 1949, decisively defeated the Kuomintang and took control of the coastal provinces in Southeast China. He ranked third among the Ten Marshals. Zhu De and Peng Dehuai were considered senior to Lin, and Lin ranked directly ahead of He Long and Liu Bocheng.
