Luding Bridge
On their way to Luding Bridge, the soldiers of the 4th regiment, 2nd division, 1st corps of the Chinese Red Army discovered that on the opposite bank, two regiments of the nationalist reinforcement were on their way to Luding Bridge. The nationalists were faster because they used torches at night, while the communists avoided them in order to move without being detected. When Red Army commander Wang Kaixiang and political commissar Yang Chengwu (杨成武) did finally decide to use torches, they were discovered by their adversaries.
