In the first stage of the Huaihai Campaign, the 1st battalion of the 75th regiment of the 9th column of the East China Field Army chased and annihilated the 63rd army of the KMT. After a rapid march for a hundred li, the troops were blocked by the turbulent Yi River when they came to the outskirts of Yantou town, Xinyi, Jiangsu province. At that moment, ten brave soldiers from the third squad of the second company braved the cold and jumped into the river; they held up two wooden ladders to build a man bridge. Then the whole battalion rushed across the bridge to the opposite side of the river and wiped out the enemies. This is one of the wooden ladders for erecting the bridge by the third squad. General Nie Fengzhi, commander of the 9th column, spoke highly of this feat and pointed out that “the action’s political significance far outweighs its military value.”
In 1959, it was transferred to the Military Museum by the 0937 troops of the former Nanjing Military Command.
