After clarifying the attack plan, Yang Zhenshan handed over Chongshan Pass to Zhou Lan, who had recovered somewhat, at the end of April, and personally led the vanguard, rearguard, and middle camps to Dinghu Guard.
At the same time, he ordered Assistant General Zhang Chengzhi from the East Road Songzhou Guard, Assistant General Niu Zhuang from the Central Road Jianning Guard, Assistant General Tang Feihu from the Central Road Jinzhou Guard, Assistant General Qin He from the Southern Road Dingliao Guard, Assistant General Yang Mingzhi from the Northern Road Fuzhou Guard, and Assistant General Yang Mingwu from the Northern Road Black Mountain Guard to lead their elite soldiers to converge at Dinghu Guard.
The vanguard, middle, and rearguard camps, in addition to the previously allocated warhorses, also brought along an extra thirty thousand warhorses. They raced along the way, fiery and swift, and covered over four hundred miles in just three days, arriving at Dinghu Guard.
