As Kara Kitan treasures had vanished, the state treasury was empty. Mahmud Bai, an immensely rich general who feared for his own wealth and substance, advised the Gurkhan to force a restoration of all that had been seized by Gutchluk and his followers. The army chiefs, unwilling to yield up their plunder, were furious on hearing this proposal. Gutchluk appeared then on a sudden, and seized his father-in-law, the Gurkhan. Once master of the sovereign’s person he used sovereign authority, so Chiluku, without power himself, retained a vain title till death took him off two years later. In 1218 the Mongol Khan marched westward, but sent Chepé Noyon in advance, with an army twenty-five thousand strong, against the Kara Kitan usurper, his enemy. Gutchluk fled from Kashgar with a part of his forces. On entering the city Chepé proclaimed freedom of religion to all men. The inhabitants massacred Gutchluk’s warriors, who had been quartered in their houses. Chepé hurried off in pursuit of the fugitive, and never drew bridle till he had hunted him over the Pamir, and caught him in the Badakshan mountains, where he cut his head off. When Jinghis heard of this he commanded Chepé not to be proud of success, for pride had undone Wang Khan of the Keraits and the Taiyang of the Naimans, as well as Gutchluk, and brought ruin to every recent ruler. This victorious Chepé some years later carried Mongol arms to Armenia across Georgia and a large part of Russia. He was of the Yissuts, a Mongol tribe which had fought against Jinghis, known at that time as Temudjin. On a day Temudjin wrought a crushing defeat on the Yissuts; Chepé fled with some others to the mountains, and hid there from death, which he looked on as certain in case he were captured. One day when Temudjin was out hunting his beaters inclosed and caught Chepé. The Khan wished to slay him, but Boörchu, his earliest comrade and one of his four chosen leaders, begged for a combat with Chepé. Temudjin agreed, and gave him a white muzzled horse for the trial. Boörchu shot an arrow which failed to reach Chepé. Chepé, more adroit than his enemy, sent a shaft which brought down the horse under him, and the next instant he rushed away with lightning speed. Reduced to want some time later Chepé offered his service to Temudjin, the strong victor. Temudjin knew the man’s worth and accepted his offer. The Khan made Chepé a chief of ten men to begin with, then of a hundred, later on of a thousand, and at last of ten thousand warriors. When Chepé brought back Gutchluk’s head he wished to give a recompense for the white muzzled horse which he killed when Boörchu attacked him, so in Kashgar he collected a thousand white muzzled horses and brought them to Jinghis as a present.
