When Arkai Kassar returned he told everything. Temudjin went to the lake called Baljuna where many of the Kurulats came to him. Juchi Kassar had disobeyed Temudjin his elder brother, he had in fact been disloyal and had tampered with the enemy. Not present at the great Kalanchin battle he had either favored Wang Khan, or been captured with his children, his wife and his followers. After that he escaped with two servants and searched in hardship and hunger for Temudjin till finally he found him at Lake Tunga. Kassar turned now to his brother’s side thoroughly, and the two men examined how best they might fall on Wang Khan unexpectedly. They worked out their stratagem and sent Haliutar and Chaurhan as if going to Wang Khan with this message from Kassar: “I have seen not a shadow of my brother; I have gone over all roads without finding him; I called him, but he heard me not. I sleep at night with my face toward the stars and my head on a hillock. My children and wife are with thee, O Khan, my father. If thou send a trusty person I will go to thee. I will return and be faithful.” “Go,” said Temudjin to the messengers, “we will leave this place straightway, when ye return come to Arhalgougi on the Kerulon.” Temudjin then commanded Churchadai and Arkai Kassar to lead the vanguard. Kassar’s two servants appeared before Wang Khan and gave him the message as if coming from their master. Wang Khan had set up a golden tent and arranged a great feast in it. When he heard the words, he said: “If that is true, let Kassar come to us.” He sent with the two messengers Iturgyan, a trusted warrior. When not far from Arhalgougi Iturgyan judged by various signs that a camp must be near them, so he turned and rushed away. Haliutar, whose horse was far swifter, spurred on ahead of him, but not venturing to seize the man, blocked the road to his stallion. Chaurhan, who followed, struck Iturgyan’s horse in the spine with an arrow, brought him down to his haunches, and stopped him. They seized Iturgyan then and took him to Temudjin, who sent him to Kassar, who killed him. The two messengers then said: “Wang Khan has made a rich golden tent; he is careless and is feasting. This is the time to attack him.” “Very well,” said Temudjin, “let us hasten.” When they arrived at the place they surrounded Wang Khan, and a fierce battle followed. On the third day of this battle the Keraits had not strength to fight longer. Wang Khan and Sengun had both vanished, no one knew by what road they had saved themselves, or when they had fled from the battle-ground.
