第4軍
In January 1941 the Nationalist forces surrounded and destroyed the headquarters of the New Fourth Army in retaliation. The New Fourth Army lost about 8,000 soldiers. The commander of the New Fourth Army was also caught. The Communist Party of China (CCP) made a strong protest and announced the rebuilding the New Fourth Army in northern Jiangsu. At this time the New Fourth Army had already seven divisions and 90,000 soldiers. Between 1941 and 1943, the New Fourth Army fought mainly with the Japanese and lost a part of base areas. Because of the heavy losses, the 6th Division's designation was revoked.
