First East Turkestan Republic
Ma's retreating forces began advancing down to southern Xinjiang to destroy the First East Turkestan Republic. He sent out an advance guard under Ma Fuyuan to attack the Khotanlik Uyghurs and Kirghiz at Kashgar. At this point Chiang Kai-shek was ready to send Huang Shaohong and his expeditionary force of 15,000 troops to assist Ma Zhongying against Sheng, but when Chiang heard about the Soviet invasion he decided to withdraw to avoid an international incident if his troops directly engaged the Soviets.
