Description：On March 18, 1943, 82 brave soldiers from the 4th Company of the 19th Regiment of the 7th Brigade of the 3rd Division of the New Fourth Army fought in Liulaozhuang, Huaiyin, Jiangsu. In order to cover the safe transfer of the main force and party and government organs, they fought tenaciously against more than 10 attacks by more than 1,000 Japanese troops as the disadvantaged party with a huge disparity in strength. Although all 82 officers and soldiers died heroically, they brought about a huge victory in which more than 170 Japanese soldiers were killed and more than 200 were injured. There are no mountains and hills, no forests and swamps, and no tall buildings to block the view. The asymmetric warfare of the forces, weapons and equipment against the enemy was carried out under impossible circumstances. Extraordinary results were achieved and an unrestricted war was fought. The 4th Company blocked and pinned down the Japanese army for more than 10 hours, successfully covering the safe transfer of the people of Liulaozhuang, and providing a great opportunity for the leadership of the New Fourth Army, the main force and the local anti-Japanese forces.
