The Second Battle of Urumqi was a conflict in the winter of 1933–1934 at Urumqi, between the provincial forces of Sheng Shicai and the alliance of the Chinese Muslim Gen. Ma Zhongying and Han Chinese Gen. Zhang Peiyuan. Zhang seized the road between Tacheng and the capital. Sheng Shicai commanded Manchurian troops and a unit of White Russian soldiers, led by Col. Pappengut. The Kuomintang Republic of China government had secretly incited Zhang and Ma to overthrow Sheng—even as they prepared to swear him in as governor of Xinjiang—because of his ties to the Soviet Union. Chinese Nationalist leader Gen. Chiang Kai-shek sent Luo Wen'gan to Xinjiang, where he met with Ma Zhongying and Zhang Peiyuan and urged them to destroy Sheng.
