Чжан Готао
The Fourth Front Army participated in the Long March as a separate unit from the main force under Zhou Enlai and Mao Zedong. At the close of the Long March, Xu Xiangqian's Right Column (to which Qin, Chen Xilian and Li Xiannian were assigned) were shattered by Muslim cavalry in a battle that might have turned out differently had Mao Zedong not abandon Fourth Front Army commander Zhang Guotao. One story has Qin and future general secretary Hu Yaobang captured in the battle and held prisoner for a year or so before finding an opportunity to escape.
