Tuul River
The Hongwu Emperor of the Ming dynasty decided to exterminate Naghachu's force in Manchuria in 1387 and two sides suffered heavier losses at a battle near Changchung city. Tögüs Temür suddenly faced a predicament in 1387 when Naghachu surrendered to the Ming due to a devastating famine. The Ming now turned their attention to the Uskhal Khan Tögüs Temür who lived in Yingchang. In 1388, he was raided by the Ming on the Buir Lake. In his escape to Karakorum, he was suddenly attacked and defeated on the Tuul River by Yesüder, a descendant of Ariq Böke, who allied with the Oirats. Yesüder's general killed the king and his son. Uskhal Khan had intended to flee westwards to join his commander Markhas. This event marked the decline of the Kublaid power and the rise of the Oirats on the Mongolian Plateau.
