Xu Da
Hongwu Emperor demanded Biligtü Khan Ayushiridara to give up his arms several times but failed. In 1372, the former dispatched the Ming army of 150,000 men to Mongolia. Biligtü Khan sent Köke Temür's army against the central division of the Ming army under Xu Da. Xu Da's troops reached Tuul River within 20 days. However, they were routed and their commander barely escaped with a few of his men. The eastern division of the Ming army advanced to Kherlen River, pillaging the Mongolian camps en route. They were suddenly defeated and forced to retreat to Orkhon where another bloody battle ensued. After that they fought the Mongol army under Halajchani and was finally defeated near Karakorum. The western division of the Ming army was forced to retreat due to other divisions' failures, though, they won a series of places.
