Temudjin and Wang Khan passed the winter on level land near the mountains where snow served as water. While there he asked in marriage Wang Khan’s granddaughter, Chaur Bijhi, for his own eldest son, Juchi, and Wang Khan mentioned Temudjin’s daughter, Kutchin Bijhi, for Sengun’s son Kush Buga. These two marriage contracts, agreed on at first, were broken later for various not well explained reasons. Jamuka was beyond doubt the great cause in this matter, and raised the whole quarrel. This rupture was followed by wrangling and coolness between the two allies, thus giving a still further chance to Jamuka. As he had never been able to estrange Wang Khan thoroughly from Temudjin he turned now in firm confidence to Sengun. He conquered Wang Khan’s son and heir with the following statements: “Temudjin has grown strong, and desires to be the greatest among men. He has determined to be the one ruler, he cannot be this unless he destroys thy whole family, he has resolved to destroy it, and he will do so unless thou prevent him. Temudjin has made a firm pact with thy enemy Baibuga, Taiyang of the Naimans; he is to get help from Baibuga, and is only waiting for the moment to ruin thy father, that done he will seize and kill thee, he will take thy whole country, and keep it.” In this way Jamuka filled Sengun’s heart with great fear and keen hatred, feelings strengthened immensely by Temudjin’s uncles, Daritai and Kudjeir, who, with Altan, his cousin, were enraged at the loss of their booty, and for other reasons. These men declared that every word uttered by Jamuka was true. A great plot was formed, and directed by Jamuka, to surprise Temudjin and kill him. Jamuka, who was watching events and working keenly, took with him Altan and others, at the end of 1202, and went again to Sengun, who was then living north of Checheher, and while attacking Temudjin spoke as follows: “Envoys are moving continually between Temudjin and the Naimans; those envoys are fixing the conditions of thy ruin. All this time Temudjin is talking of the ties between himself and thy father whom he calls his ‘father’ also. Thy father has made Temudjin his elder son. Thou art now Temudjin’s younger brother, and hast lost thy inheritance, soon thou wilt lose thy life also. Unless thou destroy this man, very quickly he will kill thee. Dost thou not see this?” When Jamuka had finished, Sengun went at once to his friends to explain and take counsel. “If we are to end him, I myself will fall on his flank. Say the word, I will do so immediately. For thee we will slay Hoelun’s children to the last one,” said Altan and Kudjeir. “I will destroy him hand and foot,” said Ebugechin. “No, take his people,” said another, “what can he do without people? Whatever thy wish be, Sengun, I will climb to the highest top with thee, and go to the lowest bottom when needed.”
