About a month after the Battle of Huangqiao, the New Fourth Army and the Eighth Route Army, with ten regiments, proactively attacked Han Deqin's remaining forces at Caodian. The assault failed to succeed; Liu Shaoqi telegraphed that casualties were about 2,000 and the expenditure was heavy.
In October 1940, a force of about 15,000 men under Han Deqin attacked Huangqiao in northern Jiangsu. Chen Yi and Su Yu commanded the New Fourth Army in a counterattack. After Weng Da's brigade was annihilated, he committed suicide, and Li Shouwei, commander of the 89th Army, drowned.
In March 1940, the Eighth Route Army concentrated 13 regiments in the Taihang Mountains to attack Nationalist forces stationed in Huai, causing their main force to rout and withdraw from the defense area.
