In 1930, Feng Yuxiang, Yan Xishan, Li Zongren Nationalist government formed an anti-Chiang alliance, and organized more than 500,000 troops in Henan, Shandong and other places with the center of Chiang Kai-shek The army launched a protracted war for the Central Plains War. In the Central Plains War, the total strength of the Central Army that Chiang Kai-shek was able to mobilize was about 600,000, which was not much different from that of the Anti-Chiang League. Neither side had a decisive advantage, so the front line in Henan fell into a stalemate, and no one had any extra reserve troops. The opponent is completely wiped out. In order to win the war, both sides set their sights on Zhang Xueliang in the northeast .
At that time, Zhang Xueliang had 300,000 elite Northeastern Army , which controlled the four provinces of Heilongjiang, Jilin, Liaoning, Rehe , and it was really strong with guns, money and money. Moreover, since the beginning of the Central Plains War, the Northeastern Army has been kept out of the matter and has been recharging its strength. It is by no means comparable to those who have been exhausted from the long-term battle on the Central Plains battlefield. It is no exaggeration to say that as long as anyone wins Zhang Xueliang's 300,000 new troops, Who can get the final victory.
In order to win Zhang Xueliang, both the Anti-Chiang Alliance and Chiang Kai-shek began to actively win over Zhang Xueliang. The ocean opening fee was used as the opening fee for entering the customs and participating in the war. At the same time, it promised to give Zhang Xueliang the control of the north of the Yellow River after the war, and appointed Zhang Xueliang as the commander-in-chief of the army, navy and air force of the Republic of China. ”.
Sep 1930,Zhang Xueliang personally led 150,000 elites from the Northeast Army to join the war and sent electricity to support Chiang Kai-shek. As soon as the news came out, the anti-Chiang alliance collapsed. Li Zongren and Yan Xishan asked Chiang Kai-shek to surrender, leaving only Feng Yuxiang to fight alone. The result can be imagined. Feng Yuxiang was defeated, and his subordinates defected from Feng Yuxiang and surrendered to Zhang Xueliang. Chiang Kai-shek fulfilled his previous promise, the Central Army did not cross the Yellow River, and Zhang Xueliang was able to control Hebei, Tianjin, Peiping, Shandong, Chahar and other places. In order to control these newly occupied areas, Zhang Xueliang transferred a large number of troops from outside the customs to garrison.
In June 1931, former Feng Yuxiang's subordinate Shi Yousan betrayed Zhang Xueliang at the instigation of Japanese spies. Shi Yousan was originally one of the "Thirteen Taibao" under Feng Yuxiang. After the Central Plains War, he joined Zhang Xueliang and was stationed in southern Hebei. After Shi Yousan's rebellion, Zhang Xueliang had to send another 6 brigades of the Northeastern Army's main force to suppress the rebellion. After more than a month of fighting, Shi Yousan's rebellion was quelled. Zhang Xueliang's control over the north of the Yellow River reached unprecedented strength, but a huge The hidden dangers are gradually exposed.
After the Shi Yousan Incident, the 6 main brigades of the Northeast Army were stranded in the customs, plus the 150,000 Northeast Army who had entered the customs before and the Northeast Army that had been recruited sporadically. At this time, the Northeast Army outside the customs was extremely empty, except Wang Yizhe's 8,000 troops stationed in Shenyang were mostly local troops, and their combat effectiveness was weak. In addition, Zhang Xueliang and a large number of senior generals of the Northeast Army were mostly stranded in the customs to deal with the post-war affairs of the Central Plains War. They had no time to care about the defense of the Northeast, and the situation in the Northeast was precarious.
Just saw this, the Japanese Kwantung Army stationed in the Lushun area started a military adventure in the early morning of September 18, which eventually triggered the most tragic incident in modern Chinese history. In less than half a year, The three provinces of Heilongjiang, Jilin and Liaoning fell.
