Jiang Qing Zhang Xueliang Xi'an Xi'an Incident United Front Red Army Long March Chiang Kai-shek He Zizhen zh
On the Long March, Mao's wife He Zizhen had been injured by a shrapnel wound to the head. She travelled to Moscow for medical treatment; Mao proceeded to divorce her and marry an actress, Jiang Qing. He Zizhen was reportedly "dispatched to a mental asylum in Moscow to make room" for Qing. Mao moved into a cave-house and spent much of his time reading, tending his garden and theorising. He came to believe that the Red Army alone was unable to defeat the Japanese, and that a Communist-led "government of national defence" should be formed with the KMT and other "bourgeois nationalist" elements to achieve this goal. Although despising Chiang Kai-shek as a "traitor to the nation", on 5 May, he telegrammed the Military Council of the Nanking National Government proposing a military alliance, a course of action advocated by Stalin. Although Chiang intended to ignore Mao's message and continue the civil war, he was arrested by one of his own generals, Zhang Xueliang, in Xi'an, leading to the Xi'an Incident; Zhang forced Chiang to discuss the issue with the Communists, resulting in the formation of a United Front with concessions on both sides on 25 December 1937.
