Oiradai Khan

Oiradtai Hagan ( 1416 - 1425 ), who declared himself the son of Delbeg, but in fact was an impostor. It seems that he was also put forward by Argutai-taiji. In any case, during his wars with the Oirats and China, Argutai continued to dominate, next to which his sister and co-commander Adai , now commander of the Khorkin military unit that had turned into a Khalkha tribe, (who lived on the Nonni River east of Khingan) moved forward.

In 1422-1424 , Argutay attacked the Chinese borders, but had to retreat far into the steppe under the Chinese retaliatory pressure, however, this Yunle steppe counterattack ( 1424-1425 ), as usual, did not bring decisive results. He was defeated and killed by his rival Adai Khan. In 1422, the Minsk emperor Zhu Di (Yongle) undertook a third military campaign against East Mongolia in order to punish Taisha Argutai. The Chinese army moved north through Kaiping and Inchan . Argutay , who camped at Lake Koluan, threw his convoy and retreated into the steppe. Then Yunle turned against the Uryanhai, the allies of Aruktai, inflicting a complete defeat on them in the battle on the Qu-le-he river.

The following year, 1423, Taisha Argutay organized new raids on border Chinese possessions. In response, the Chinese emperor Yongle with a large army invaded deep into Mongolia, but could not find Argutay. In the autumn of the same year, 1423 Argutay suffered a serious defeat from the Oirats. Upon learning of the defeat of Argutai, Yunle returned to Beijing with the Chinese army. In 1424, Argutay ravaged the Chinese provinces of Datong and Kaiping . Then the Chinese emperor Yongle again set out on a punitive expedition to Mongolia. Yongle reached the Dolonor River, where he learned that Argutai had stumbled far into the steppe.
