Xian Incident

During World War 2, Generalissimo Chiang Kai-Shek, Commander in Chief of National Revolutionary Forces of the Kuomintang, refused to ally with the Communist Party of China to fight against Japanese, and instead opted to fight both at once.

Generals Zhang Xue-liang and Yang Hu-cheng[?] of Kuomintang (with the support of communist leader Zhou Enlai), kidnapped Chiang Kai-shek and forced him to join an united front with the communists against the Japanese.

Even though the ceasefire was in effect, the armies were never under a common command and the KMT never fully cooperated.

After the war, the two generals were placed under permanent house arrest by Chiang and were brought over to Taiwan along with retreating KMT forces.
