On this day, 96 years ago, May 15, 1929 (April 7, 1929 in the lunar calendar), Chiang and Feng went to war, and Han Fuju and Shi You rebelled against Feng and supported Chiang. Feng Yuxiang's troops gathered in Hongchang, Tongguan, Shaanxi Province to prepare for the crusade against Chiang In mid-May 1929, after Feng Yuxiang deployed anti-Chiang military operations in Huayin, Shaanxi Province, the first military conflict between Chiang and Feng began. The military conflict between Chiang and Feng originated from the Shandong incident. In March, Japan and the Nanjing government signed an agreement to withdraw from Jinan. According to the agreement, Jinan should be taken over by the Northwest Army, which is responsible for Shandong's defense. Chiang Kai-shek urgently ordered the Northwest Army not to accept Jinan and notified Japan that the Central Army would take over Jinan. The conflict between Jiang and Feng intensified. Chiang wanted to eliminate Feng's troops, but Feng also decided to turn against Chiang. On May 16, the generals of the Northwest Army issued an anti-Chiang telegram, promoting Feng Yuxiang as the "Commander-in-Chief of the Northwest Road of the Party and National Salvation Army" and starting military operations. On the 17th, the National Government sent a telegram to accuse Feng Yuxiang and immediately issued a punitive order. Chiang also appointed Tang Shengzhi as the commander-in-chief of the fifth route to defeat the rebels, and to resist Tang and Feng. On the 19th, Feng Yuxiang held a military meeting in Huayin, Shaanxi Province to deploy anti-Chiang. On May 22, Feng Yuxiang's generals Han Fuju and Shi Yousan sent a telegram to support Chiang and betray Feng Yuxiang. During the Jiang-Guangxi War, Han Fuju was ordered to lead a unit of the Northwest Army to participate in the attack on Wuhan. After Chiang Kai-shek occupied Wuhan, he summoned Han Fuju and promised Han to be appointed chairman of Henan Province. He gave him hundreds of thousands of yuan to make Han surrender to Chiang. Han Yuan was Feng Yuxiang's loyal general, but Feng's troops lived a difficult life and managed the army strictly. Han was eventually bought over by Chiang. Chiang also sent someone to send hundreds of thousands of yuan to Shi Yousan in Xiangfan. Shiben was capricious and immediately expressed his willingness to obey Chiang's command. After the Jiang-Guangxi War ended, Feng Yuxiang heard about this and only let Han serve as chairman of Henan Province and deprived Han of his military power. This move aroused Han's dissatisfaction even more. After the Huayin Military Conference, Han immediately returned to his old troops, imprisoned the commander sent by Feng, and pulled his old troops from Shanzhou to Luoyang, leaving Feng Yuxiang. After Han and Shi defected, Chiang Kai-shek appointed them as chairmen of Henan and Anhui Province respectively in order to reward them, and awarded them 5 million yuan as expenses. The defection of Han and Shi led to Feng Yuxiang's defeat in the conflict with Chiang. On the 23rd, the Central Committee of the Kuomintang ordered the removal of Feng Yuxiang from all positions and permanent expulsion from the party. Faced with Chiang's strong pressure, Feng acted cautiously and issued a telegram on the 27th, which deprived Chiang of the excuse to attack and ended the military conflict between Chiang and Feng.
