Outside Zhangjiakou, Li Xuan finally bit a significant chunk out of the more than two hundred thousand Oirat cavalry.
He took advantage of the voluntary retreat of the entire Wala army to make a cavalry charge shielded by the Yunzhong warship, followed by an infantry advance in support.
The Khan of Vala, Yexian, once again experienced the fierce ruthlessness and wolf-like ferocity and greed of Li Xuan's military strategy.
He had actually arranged enough troops to cover the rear and coordinate support, with the army retreating in a staggered manner and protecting each other front and back.
But this hardly played any role, as Li Xuan temporarily formed two units equipped with a large number of muskets and Hudun cannons, who were also skilled in equestrianism.
They were positioned on both sides of the cavalry, using their horses' speed for quick maneuvers, then dismounting for infantry combat and close-range shooting.
