1On May 29th, 935, the First Army of the Chinese Workers and Peasants Red Army marched here. The enemy troops on the defensive demolished most of the bridge deck and built fortifications at the east bridge head to block the bridge deck. The vanguard of the Left Army, the Red Fourth Army, organized a storm. Twenty-two Red Army soldiers braved the bullets and crawled along the iron chain to seize the Luding Bridge, enabling the whole army to cross the Dadu River smoothly.
