Location: Wuyuan 🌎

The Battle of Wuyuan (March 16 – April 3, 1940; Chinese: 五原戰役) was a Chinese counterattack that defeated the Japanese invasion of the Wuyuan area. This happened in reaction to the Chinese 1939-40 Winter Offensive in Suiyuan during the Second Sino-Japanese War. The Japanese call it 第２次後套作戦 (“The Second Battle of Wuyuan”). By the 28th of January 1940 the Japanese had built up forces from the 26th Division at Baotou sufficient to launch the 第１次後套作戦 or “First battle of Wuyuan in Inner Mongolia” to recover lost territory and move west to take Wuyuan which fell on February 3 and Linhe further west on the 4th of February.
