Note 1 — Chapter III · WANG KHAN OF THE KERAITS

In 1199 the two allies marched to attack the Naimans, a people strong and famous while under Buga Khan, an able ruler, but when this Khan died his two sons, to gain a certain concubine left by their father, began a murderous quarrel, which brought about the division of the country. The elder man, Baibuga, called Taiyang,1 by his subjects and his neighbors, retained the level country, while Buiruk, his brother, took mountain places. Each ruled alone, and each was an enemy of the other. Wang Khan and Temudjin, remembering former robberies by the Naimans, and wishing too to add wealth and power to what they themselves had, attacked Buiruk at Kizil Bash near the Altai. They seized many captives and much precious booty. Buiruk then moved westward followed closely by the allies and fighting with great vigor. One of his leaders, Edetukluk, who brought up the rear guard, fought till his men were all slain, or made prisoners. He struggled alone then till his saddle girth burst, and he was captured.
