Saïn Tegin fell ill and they called in a shaman of the Taidjuts to cure him. He died notwithstanding the art of this shaman, who was slain either on his way home or soon after, by the relatives of the dead man. This caused a great battle between the Taidjuts and Saïn Tegin’s adherents and relatives, joined now by Kabul’s sons, who favored the cause of their uncle. In this battle Kaidan met a Taidjut in single encounter, split open his saddle, swept him down from his horse, and wounded him dreadfully. The Taidjut, who recovered only after a twelve month of suffering, began a new struggle as soon as strength came to him. Kaidan brought horse and rider to the earth, each wounded grievously; though ten mounted men rushed at the victor, he so used spear and sword on them that he came out in triumph. Thus began the great blood feud which later on Temudjin used with such deadly effect on the Taidjuts and Tartars. Between Lake Buyur and Lake Kulon is a river, on this river a large group of Tartar tribes lived at that period. Ambagai, son of Sengun, went to find a new wife at Lake Buyur but was seized by some Tartars and sent to the Kin Emperor, who took his life very cruelly. Before his captors had set out with Ambagai he sent home this message: “Tell Kutula, fourth son of my cousin Kabul, who has seven sons, and Kaidan, one of my ten sons, that I, who ruled men, am a prisoner and must die in great suffering. And remember these words of mine, all of you: Though ye were to wear every nail from the fingers of each hand, and lose the ten fingers on both hands, ye must avenge me.” The Golden Khan in return for offenses committed against him by Ambagai’s relatives, had him nailed to a wooden ass, flayed alive, and then chopped into small pieces slowly, beginning with his fingers and toes, till his whole body was finished. Okin Barka, Kabul’s eldest son and a brother of Kutula, had been captured by the Tartars, sent to the Golden Khan, and put to death in the same way as Ambagai. This was done because Kabul had killed the Golden Khan’s messengers.
