Taichiud, commanded by Targhutai Kiriltuk, an old enemy of Temujin, and Merkit led by Toqto'a Beki, who had recently recovered his son on the banks of the Onon River. Relationship with Jamukha In 1201, Jamukha had resumed hostilities against Temujin. An impressive coalition of Mongol tribes of Taichiud, Ikires, Qorolas, Salji'ut, Dörbet, Suldus, Qatagin, Besud, Merkit, Oirat and finally Tatars recognized Jamukha as "Khan Universal" (Gurkhan). Toghrul decided to back Temujin in order to oppose growing power of Jamukha. Toghrul, Jakha Gambu and Temujin went into the valley called the Kerulen Valley with 15000 men. When they saw the enemy, they climbed the mountains because they were shorthanded against the enemy. It was also when Buyruq khan joined Jamukha.

Ambitious Ilga joined forces with Jamukha, Altan and Qutchar, who persuaded him to eliminate Temujin. Ilga attempted to assassinate him, failed, and then confronted the hordes of Temujin in a fierce battle in which he was wounded.
