长沙会战
Starting in 1942, Nationalist China diverted troops to retake the province of Xinjiang from the Soviet client-state of Sheng Shicai, whose army was supported by the Soviet Red Army's 8th Regiment in Hami, Xinjiang. The Soviets became involved in the province during the Soviet invasion of Xinjiang in 1934, where the Soviets occupied northern Xinjiang. The Soviets obtained control over the rest of Xinjiang after the Islamic rebellion in Xinjiang in 1937, placing all the province under Sheng Shicai control. The fighting then escalated in early 1944 with the Ili Rebellion; the Soviet-backed Uyghur Communist rebels forced China to commit 120,000 troops in opposition to the rebellion. Compounding the previous difficulties, The Republic of China's Nationalist forces had become overconfident after a string of three victories in defense of Changsha; the Battle of Changsha (1939), the Battle of Changsha (1941), and the Battle of Changsha (1942).
