徐達
In 1370 when Toghun Temur died and Ayushiridara succeeded to the throne, Koke Temur entered the Mongolian Plateau from Gansu and joined the new khan, who was based in Khara Khorum. He undertook the defense of the khan. The Hongwu Emperor invited him seven times and offered bribes. But Koke Temur did not abandon his khagan in his misfortune. The most notable service was an overwhelming desert victory over a Ming army led by Xu Da in 1372. It is said that he killed 20,000 Ming soldiers. But in a further encounter against Xu Da in Gansu, Köke Temür's army was badly mauled by the Chinese and forced to flee across the Gobi desert.
