The departure of Suta emboldened Kuku Timour so far as to lead him to take the field, and he hastened to attack the town of Lanchefoo, the capital of Kansuh, where there was only a small garrison. Notwithstanding this the place offered a stout resistance, but the Mongols gained a decisive success over a body of troops sent to its relief. This force was annihilated and its general taken prisoner. The Mongols thought to terrify the garrison by parading this general, whose name should be preserved, Yukwang, before the walls, but he baffled their purpose by shouting out, "Be of good courage, Suta is coming to your rescue." Yukwang was cut to pieces, but his timely and courageous exclamation, like that of D'Assas, saved his countrymen. Soon after this incident Suta reached the scene of action, and on his approach Kuku Timour broke up his camp and retired to Ninghia. The Chinese commander then hastened to occupy the towns of Souchow and Kia-yu-kwan, important as being the southern extremity of the Great Wall, and as isolating Ninghia on the west. Their loss was so serious that the Mongol chief felt compelled to risk a general engagement. The battle was keenly contested, and at one moment it seemed as if success was going to declare itself in favor of the Mongols. But Suta had sent a large part of his force to attack the Mongol rear, and when this movement was completely executed, he assailed the Mongol position at the head of all his troops. The struggle soon became a massacre, and it is said that as many as 80,000 Mongols were slain, while Kuku Timour, thinking Ninghia no longer safe, fled northward to the Amour.

Among the prisoners was the eldest grandson of Chunti, and several of the ministers advised that he should be put to death. But Hongwou instead conferred on him a minor title of nobility, and expressed his policy in a speech equally creditable to his wisdom as a statesman and his heart as a man:
