Mingan had hardly captured Chong tu when Jinghis sent Samuka with ten thousand men to fall on Nan king and capture the Emperor. Samuka marched up so close to the city that he was only two leagues from it, but his troops being few, he was forced to retreat empty-handed. He made a second attempt the year following and was nearer success without reaching it. Meanwhile the Kin dynasty was approaching its doom, and the day of extinction. In the spring of 1216 Jinghis, from his home on the Kerulon, again sent Subotai against the brother and three sons of Tukta Bijhi, the last Khan of the Merkits. Tuguchar was to help should the need come. Subotai met the Merkits near the Jem River in the Altai and defeated them. Two sons of Tukta Bijhi and Kutu, his brother, were slain in the action; the third son, Kultuk Khan, a great archer, was captured and taken to Juchi, eldest son of Jinghis. When Juchi asked for a proof of his skill, the young man sent an arrow into a goal, and then split that first arrow with a second one. Juchi begged his father to spare this Kultuk, [8] but in vain. This great archer, the last son of Tukta Bijhi, had to die like the others. While the Mongol Khan was in China, Baitulu, who was chief of the Tumats, withdrew from obedience. At command of Jinghis, Boroul marched in 1217 against the Tumats and crushed them, but lost his own life in the conflict, which was close and very bitter. Jinghis had asked aid of the Kirghis. But they too rose against him, and Juchi was sent to reduce this recalcitrant people. He did the work thoroughly before leaving the upper waters of the Irtish and the Yenissei. In 1214 Mukuli had been sent, as we remember, to the Kitans, whose country had been greatly overrun by Kin armies. During the two years which followed, this best of all Mongol leaders won back that whole region by excellent strategy, finesse, and grand fighting. This work was indispensable in the conquest of China. During 1217 this great general appeared before Jinghis encamped then on the Tula. Mukuli was rewarded beyond all other generals up to that day, and after it. Jinghis praised him in public, lauded his great mental gifts, and his services, called him Kwe Wang, or prince in the Empire, and made this title hereditary. He created him lieutenant commanding in China, and gave him a seal made of gold as a sign of authority. “I have conquered the North,” said Jinghis, “subdue thou the South for me.” And he dismissed him with an army of Mongols and Kitans, with the Jutchis, or Manchus, to help them. In 1218 Jinghis marched on Tangut for the fourth time and brought it to obedience. During that year he received the submission of Corea. Next his activity was turned to a new side, and soon we shall see the opening scenes in that mighty movement begun by Jinghis and continued by his descendants, and still later resumed by his relative, the tremendous Timur, that World Shaking Limper and father of the Mongol rulers of India.
