War is about courage. Once the drum is sounded, the courage surges, but it wanes the second time, and it is exhausted by the third.
When Great Chu began its counterattack, the Tartars were continuously defeated. Not to mention Wala's defection at the battlefield, even the Tartars themselves were on edge.
The leaders who led the army to battle were the same ones who had once resisted Bashahan alongside the Northwest Army. While ambushes were manageable, now in a direct battle, they recalled how the Northwest Army had once stormed through Shangjing and captured Bashahan with overwhelming momentum, and their morale was distinctly weakened.
When one weakens, there must be a stronger force. The Tartar Army was utterly defeated in one blow, while the Northwest Army seemed to be divinely assisted wherever they went; even in terrain warfare, they never lost.
