The Japanese offensive called 太原作戦 or the
Battle of Taiyuan () 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 guerrilla 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.
Chronology
In September 1937,
Hideki Tojo sent the Japanese army stationed in
Chahar to invade
Shanxi in order to exploit its resources. The city of
Datong fell, and the
NRA was forced to go on the defensive, and concentrated their troops along the
Great Wall in battles at places like
Pingxingguan and to the east at in
Niangziguan.
Yan Xishan also 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.
