Battle of Taiyuan
1937 Japanese victory

The Battle of Taiyuan was a major battle fought in 1937 between China and Japan named for Taiyuan (the capital of Shanxi province), which lay in the 2nd Military Region. The battle concluded in a victory for Japan over the National Revolutionary Army (NRA), including part of Suiyuan, most of Shanxi and the NRA arsenal at Taiyuan, and effectively ended large-scale organized resistance in the North China area.

Yan Xishan sent troops to reinforce Shijiazhuang, but that caused a lack of personnel to defend the North China area, allowing the Japanese army to break through in the north forcing the Chinese to fall back to a new line at Xinkou. Fighting continued in October in the Battle of Xinkou until the Japanese outflanked Niangziguan in late October, compromising the Chinese defense resulting in the fall of Taiyuan.
