Battle of Urumqi was a conflict that took place in the winter of 1933-1934 at Urumqi, between the provincial forces of Sheng Shicai, and the alliance of the Chinese muslim general Ma Zhongying and Han chinese general Zhang Peiyuan.[1][2] Zhang seized the road between Tacheng and the capital.[3] Sheng Shicai commanded manchurian and white russian troops commanded by Colonel Pappengut.[4][5] The KuomintangRepublic of China government had secretly incited Zhang and Ma to overthrow Sheng, even as they prepared to swear Sheng in as governor of Xinjiang, because of his connections with the Sovet Union. Ma and Zhang's Han chinese and chinese muslim forces almost defeated Sheng, when Sheng requested help from the Soviet Union. This led to the Soviet Invasion of Xinjiang and Ma Zhongying's retreat after the Battle of Tutung.
