This victory aroused the jealousy of certain tribes which were as yet independent of Temudjin, namely, the Kunkurats, Durbans, Jelairs, Katakins, Saldjuts, and Taidshuts, and they formed a confederacy to put him down. We are told that their chiefs met at a place called Aru Bulak, and sacrificed a horse, a bull, a ram, a dog, and a stag, and striking with their swords, swore thus: "Heaven and earth, hear our oaths, we swear by the blood of these animals, which are the chiefs of their kind, that we wish to die like them if we break our promises."
The plot was disclosed to Temudjin by his father-in-law, Dai Setzen, a chief of the Kunkurats. He repaired to his ally, Wang Khan, and the two marched against the confederates, and defeated them near the Lake Buyur. He afterward attacked some confederate Taidshuts and Merkits on the plain of Timurkin, _i.e._, of the river Timur or Temir, and defeated them. Meanwhile the Kunkurats, afraid of resisting any longer, marched to submit to him. His brother, Juji Kassar, not knowing their errand, unfortunately attacked them, upon which they turned aside and joined Chamuka.
That inveterate enemy of Temudjin had at an assembly of the tribes, Inkirasses, Kurulasses, Taidshuts, Katakins, and Saldjuts, held in 1201, been elected gurkhan. They met near a river, called Kieiho by Mailla; Kian, by Hyacinthe; and Kem, by Raschid, and then adjourned to the Tula, where they made a solemn pact praying that "whichever of them was unfaithful to the rest might be like the banks of that river which the water ate away, and like the trees of a forest when they are cut into fagots." This pact was disclosed to Temudjin by one of his friends who was present, named Kuridai. He marched against them, and defeated them at a place north of the Selinga, called Ede Kiurghan, _i.e._, site of the grave mounds. Chamuka fled, and the Kunkurats submitted.
In the spring of 1202, Temudjin set out to attack the tribes Antshi and Tshagan. These were doubtless the subjects of Wangtshuk and Tsaghan, mentioned by Ssanang Setzen. They were probably Tungusian tribes. The western writers tell us that Temudjin gave orders to his soldiers to follow up the beaten enemy, without caring about the booty, which should be fairly divided among them. His relatives, Kudsher, Daritai, and Altun, having disobeyed, were deprived of their share, and became, in consequence, his secret enemies. Ssanang Setzen has much more detail, and his narrative is interesting because, as Schmidt suggests, it apparently contains the only account extant of the conquest of the tribes of Manchuria. He says that while Temudjin was hawking between the river Olcho and the Ula, Wangtshuk Khakan, of the Dschurtschid (Niutchi Tartars of Manchuria), had retired from there. Temudjin was angry, and went to assemble his army to attack the enemy's capital. But as a passage was forbidden him across the river Ula, and the road was blockaded, the son of Toktanga Baghatur Taidshi, named Andun Ching Taidshi, coupled ten thousand horses together by their bridles, and pressed into the river, forced a passage, and the army then began to besiege the town.
