The topography of the Joseon Peninsula is characterized by low-lying terrain in the southwest and high elevations in the northeast. Over eighty percent of the land is comprised of mountains or hills, with the few plains located along the western coastal strip. The Western Route Army, led by Li Dingguo, advanced through this flat region; logically, once they had captured Uiju, they could have pushed rapidly southward.
However, Li Dingguo did not. His mission for this campaign into Joseon was to root out the Jiannu entirely, necessitating a tactical shift.
By midday, the Ming Army had occupied the city of Uiju. The deputy general, Dou Mingwang, approached Li Dingguo, stating, "General, the garrison commander of Uiju is waiting outside."
