After Japan launched the 918 Incident and the occupation of the northeast, Zhang Xueliang withdrew with the northeast army, and never returned to the northeast. Because Zhang Xueliang was influenced by Premier Zhou's anti-Japanese ideas, he launched the Xi'an Incident and put Chiang Kai-shek under house arrest. After Chiang Kai-shek promised to resist Japan in an all-round way, Zhang Xueliang personally sent Chiang Kai-shek home, and as a result, he was detained as soon as he arrived. And Zhang Xueliang went, the 200,000 troops under his hands, directly fell into the situation of the leaderless dragons.
After Zhang Zuolin's death, the Northeast Army was inherited by Zhang Xueliang, and later the Japanese army occupied the three northeastern provinces, and the northeast also became a colony. At that time, Zhang Xueliang had no choice but to force Chiang Kai-shek to resist Japan together with Yang Hucheng, and the Xi'an Incident broke out, and Chiang Kai-shek was forced to resist Japan unanimously throughout the country. After Chiang Kai-shek agreed, Zhang Xueliang sent him back to Nanjing, but he never returned. However, at that time, the Northeast Army under Zhang Xueliang learned that Zhang Xueliang was detained, what were they doing? Why didn't anyone go to save him?
After the Xi'an Incident broke out, Chiang Kai-shek's troops rushed directly to the front line and surrounded Zhang Xueliang's Northeast Army. When the Northeast Army withdrew from the northeast, it had nothing left and could only rely on Chiang Kai-shek's rescue, otherwise it would be difficult to continue to develop. When the Central Army rushed to the front line and surrounded all the Northeast Army, it did not provide military food to the Northeast Army, and at this time, the Northeast Army had no strength to resist.
Zhang Xueliang's Northeast Army accepted his father, and when his father was alive, he led the troops in the way of morality, so the military discipline management was not strict, and the internal corruption and paralysis had long been corrupt. After Zhang Xueliang accepted it, of course, he also had to respect the veteran generals in the army, and it was also very difficult to control the army. Some of Zhang Xueliang's generals received Chiang Kai-shek's benefits, and the military's morale had been scattered, so naturally there was no one to save Zhang Xueliang.
