Luding Bridge
Lin Biao has commonly been given credit for direct command of the assault. However, the actual commander was the regimental political commissar Yang Chengwu. Lin Biao and other column commanders remained at their temporary headquarters 160 km away from Luding Bridge, and the task of taking the bridge was given to Lin Biao's vanguard unit, the 4th regiment, as it was 40 km closer to Luding. The regiment was led by commander Wang Kaixiang (王开湘) and political commissar Yang Chengwu (杨成武). Credit was publicly given to Lin Biao during the Cultural Revolution, in which he was glorified to boost his popularity. Giving him direct credit for jobs accomplished by his subordinates was one of the standard propaganda techniques. During the Cultural Revolution, the actual commander, Yang Chengwu was jailed and persecuted under the direct order of Lin Biao.
