Encircling and Entrapping
Not mentioning Shi Wanshui who was in the middle of the chariot circle formation and slaughtering in all four directions, outside of the formation, Baiqi had left the Lang Mountain and personally started to command the troops.
Two hundred thousand troops under Baiqi's command had broken layer after layer of the chariot circle formation.
After the formation lost its middle command, although it was barely working, it had already lost its spine. It wasn't as smooth and coordinated and was now just a dead formation.
Comparatively, the Qin army under Baiqi's lead, be it attacking from the front or the back, coordination between infantry and cavalry, baiting the enemy or attacking upfront, was completely superior.
All these many forms, Baiqi commanded them like they were a whole body, precisely eating away at the Zhao army. The Zhao army was split into a few layers, and their advantage had instantly became their burden.
