孫立人
In August 1947, Chiang appointed Chen as director of the Northeastern Headquarters to command the Nationalist forces against the Communists in that area. He made the crucial mistake of dissolving the local security regiments because they had served in the Japanese-collaborationist Manchukuo Imperial Army, which made the total Nationalist strength in Manchuria fall from 1.3 million to less than 480,000. He also dismissed some of the most capable Nationalist commanders, such as Du Yuming, Sun Li-jen, Zheng Dongguo, and Chen Mingren. As a result, he suffered a series of major defeats, and Chiang recalled Chen to Nanjing and sent Wei Lihuang to replace him in Shenyang as Commander-in-Chief of the Northeast and Fan Hanjie as deputy commander-in-chief and director of Jinzhou forward command center. Chen took a sick leave in Taiwan to treat his chronic stomach ailment.
