In page Yunus Khan:

"

Despite his success in making allies, Yunus did not succeed in his project of displacing Esen Buqa, perhaps because he had no experience of war. When Yunus moved to take the town of Kashgar, he was faced by the joined armies of Amir Sayyid Ali of Kashgar and Esen Buqa, and in the ensuing battle, he was defeated. Soon afterwards, he retreated from Moghulistan and returned to the court of Abu Sa'id, who gave him territory around Lake Issyk-Kul as a fiefdom (in appanage). After a while, Yunus Khan again entered Moghulistan and again gained the support of the amirs, but was again unable to make any substantial gains in the country against Esen Buqa.
