Zhang Zuolin was a veritable tyrant in the Republic of China period, he was originally only born in the grass, but step by step he stepped onto the throne of the King of northeast China. At the same time, when the Northern Expeditionary Army swept the whole country, he was also the last ruler of the Beiyang regime, and he had enough strength to compete with the Northern Expeditionary Army. He was even elected as the commander-in-chief of the An Guo Army with the support of Zhang Zongchang and Sun Chuanfang, and the scenery was unique for a while.
It was not until Chiang Kai-shek was supported by super-powerful warlords such as Feng Yuxiang and Yan Xishan that the An Guo army was defeated. At this time, Zhang Zuolin still has a way to retreat, and he can return to Guanwai to continue to be his local overlord. Then Zhang Zuolin did not know that at this time he had been targeted by the Japanese, and then the Huanggutun Incident broke out, and Zhang Zuolin was killed.
After Zhang Zuolin's death, the 400,000 troops of the Feng army fell into the hands of Zhang Xueliang, and Zhang Xueliang naturally knew that the Kwantung Army was his father's enemy, but why didn't Zhang Xueliang immediately avenge his father?
The first is because Zhang Xueliang's new king ascended the throne and his foothold was unstable. At that time, many important generals of the Feng Army were zhang Xueliang's uncles, and their prestige was higher than Zhang Xueliang, and people like Yang Yuting, who were flying and stumbling, did not pay attention to Zhang Xueliang, at this time, even if Zhang Xueliang wanted to take revenge, he might not be able to mobilize the soldiers in the hands of others.
Although the number of the Japanese Kwantung Army is not large, but behind the Kwantung Army is the entire Japanese country, and Zhang Xueliang's soldiers are only large in number, and the weapons and equipment are relatively backward.
The third reason was that Chiang Kai-shek's Northern Expeditionary Army was still fierce at that time, and the only remaining local force that did not submit to the Nationalist government was the Feng Army. Therefore, Zhang Xueliang could only give priority to the future of Fengjun, so he chose to defect to Chiang Kai-shek, and Fengjun became the Northeast Army.
After Zhang Xueliang had gained absolute say in the Northeast Army, the Japanese launched the September 18 Incident, and at this time Chiang Kai-shek's policy was not to resist, forcing 400,000 Northeast Troops to withdraw to Guannei and surrender the Northeast to the northeast. After Zhang Xueliang obeyed Chiang Kai-shek's orders, he basically had no chance to fight the Japanese again.
Zhang Xueliang was then transferred by Chiang Kai-shek to fight with the Red Army, and it was not until the Xi'an Incident broke out that Zhang Xueliang finally hardened his temper. However, after the peaceful settlement of the Xi'an Incident, Zhang Xueliang was immediately put under house arrest by Chiang Kai-shek, which also meant that Zhang Xueliang's military career was directly declared over, and Zhang Xueliang had no chance to avenge his father from then on.
