At the same time, Yue Fei personally led an elite force, bypassing the frontline battlefield, and launched a surprise attack on Liu Qi's last supply station in the rear.
The news spread, and Liu Qi's army was utterly demoralized.
Before the main forces of the Northern Border Army could encircle them, some officers led the dispirited soldiers to flee south under the cover of night.
Liu Qi could not maintain control and, knowing the situation was lost, sighed deeply and could only lead the remaining forces in a hasty retreat.
The Right Route Army thus disintegrated.
Immediately afterward, the pressure was directed toward Yang Yizhong's isolated Left Route Army.
Upon hearing of Liu Qi's defeat and the side being exposed, Yang Yizhong was shocked and terrified.
Yue Fei, emboldened by his victory, quickly returned to his forces, positioning them to cut off Yang Yizhong's retreat.
