that they would take the oath of
allegiance to him. This they readily agreed to do. There were a great
many subordinate khans, both of this tribe and of some others that
were near, who thus yielded to Temujin, and promised to obey him.

All this took place, as has already been said, immediately after the
great battle with Tayian, and before Temujin had been enthroned as
emperor, or had received his new title of Genghis Khan. Indeed,
Temujin, while making this expedition to Kashin in pursuit of Kushluk
and Tukta Bey, had been somewhat uneasy at the loss of time which the
campaign occasioned him, as he was anxious to go as soon as possible
to Karakorom, in order to take the necessary measures there for
arranging and consolidating his government. He accordingly now
determined not to pursue the fugitives any farther, but to proceed at
once to Karakorom, and postpone all farther operations against Kushluk
and Tukta until the next season. So he went to Karakorom, and there,
during the course of the winter, formed the constitution of his new
empire, and made arrangements for convening a grand assembly of the
khans the next spring, as related in the last chapter.

In the mean time, Tukta Bey and the Prince Kushluk were very kindly
received by Boyrak, Tayian's brother. For a time they all had reason
to expect that Temujin, after having taken and destroyed Kashin, would
continue his pursuit of the prince, and Boyrak began accordingly to
make preparations for defense. But when, at length, they learned that
Temujin had given up the pursuit, and had returned to Karakorom, their
apprehensions were, for the moment, relieved. They were, however, well
aware that the danger was only postponed; and Boyrak, being determined
to defend the cause of his nephew, and to avenge, if possible, his
brother's death, occupied himself diligently with increasing his army,
strengthening his fortifications, and providing himself with all
possible means of defense against the attack which he expected would
be made upon him in the coming season.

Boyrak's expectations of an attack were fully realized. Temujin, after
having settled the affairs of his government, and having now become
Genghis Khan, took the first opportunity in the following season to
fit out an expedition against Tukta Bey and Boyrak. He marched into
Boyrak's dominions at the head of a strong force. Boyrak came forth to
meet him. A great battle was fought. Boyrak was entirely defeated.
