Japanese Forces Take Taiyuan and Surrounding Area, Ending Large-Scale Resistance in the North China Area
The Japanese offensive called 太原作戦 or the Battle of Taiyuan (traditional Chinese: 太原會戰; pinyin: Tàiyuán Huìzhàn; Wade-Giles: T'ai-yüan Hui-tsan) was a major battle fought between China and Japan named for Taiyuan (the capital of Shanxi province), which lay in the 2nd Military Region. This battle concluded in loss for the NRA, including part of Suiyuan, most of Shanxi and their most modern arsenal at Taiyuan and effectively ended large-scale regular resistance in the North China area. With these territories occupied, the Japanese obtained the coal supply in nearby Datong, but it also exposed them to attacks by the guerilla forces of the Nationalist army including the Eighth Route Army, tying down a large number of Japanese troops which could have been diverted to other campaigns.
Fighting raged throughout Western China. Quickly Japan seized the major coastal cities, and much of the countryside. Nationalist Chinese units, plagued by lack of supplies, corruption, and poor training, fell back on a wide front.
