At the Black Forest Temudjin became elder son to Wang Khan. Up to that time he had called the old chieftain his father through friendship, because he and Yessugai had both been his “andas” and allies. Now Wang Khan and Temudjin used the words “son” and “father” in conversing and with their real value. This adoption of Temudjin excluded Sengun in reality from the earliest inheritance, and Temudjin knew well, of course, that immense opposition would come from Sengun and Jamuka. “We shall fight side by side in war against enemies,” said Wang Khan to his new elder son. “In going against wild beasts we are to hunt with common forces. If men try to raise quarrels between us we will lend no ear to anyone, and believe only when we have met and talked carefully together over everything, and proved it.” Thus they decided, and their friendship on that day was perfect. The crushing defeat of the Naimans, which lowered them much, immediately raised Temudjin above every rival. Jamuka’s plotting had turned against himself most completely, and if he had planned to help Temudjin he could not have helped better. Somewhat later Juchi Kassar snatched another victory from the Naimans, and weakened them further. Tukta Bijhi, the Merkit chief, sent Ordjank and Kutu, his brothers, to rouse up the Taidjuts afresh against Temudjin. Ongku and Hakadju took arms and made ready to help Targutai, the Taidjut chief, with Kudodar and Kurul. Temudjin and Wang Khan marched in the spring of 1200 and met those opponents at the edge of the great Gobi desert, where they crushed them completely. Targutai and Kudodar were both slain. Targutai was the man who had acted so bitterly against Temudjin after his father was poisoned. This Taidjut leader fell now at the hand of Jilaun, a son of that same Sorhan Shira, who had rescued Temudjin from the river Onon, taken the kang from his neck and hidden him under wool racks. Hakadju and Ongku, who had helped on this war by enabling Tukta Bijhi to rouse up the Taidjuts fled now to Bargudjin with Tukta Bijhi’s two brothers, while Kurul found a refuge with the Naimans. Still this defeat did not end Taidjut rancor. The Katkins and Saljuts shared also this hatred. Temudjin strove however, to win them, and sent an envoy with this message: “Each Mongol clan should support me, I then could protect all without exception.” This envoy was insulted; some snatched entrails from a pot and slapped his face with them; they struck him right and left and drove him off amid jeers, and loud howling.
