1939–1940 Winter Offensive

The 1939–1940 Winter Offensive (Chinese: 冬季攻勢) was a major engagement between the National Revolutionary Army and Imperial Japanese Army during the Second Sino-Japanese War. It constitutes the first major counter-offensive on multiple fronts of Chinese forces in the war. Although it failed to achieve its original objectives, later studies have shown that it came as a blow to the Japanese forces.
