Zhang Zhizhong
Between 1935 and 1945 Feng Yuxiang supported the KMT and held various positions in the Nationalist army and government. In October 1935 Chiang invited him to Nanjing to serve as the vice-president of the Military Affairs Commission. He held the nominal position until 1938 and remained a member of the council until 1945. During the Xi'an Incident, when Chiang Kai-Shek was held prisoner by rebellious warlords, Feng immediately called for Chiang's release. After the Second Sino-Japanese War began in 1937 he briefly served as Commander-in-Chief of the 3rd War Area. In this capacity Feng led Chinese forces early in the defense of Shanghai, but he was quickly relieved in favor of Zhang Zhizhong and later Chiang himself.
