Being thus regularly placed in command, Temujin began by giving places of honor and authority to those who left Vang Khan's service to follow him. He took this occasion to remember and reward the two slaves who had come to him in the night at his camp, some time before, to give him warning of the design of Sankum and Yemuka to come and surprise him there. He gave the slaves their freedom, and made provision for their maintenance as long as they should live. He also put them on the list of _exempts_. The exempts were a class of persons upon whom, as a reward for great public services, were conferred certain exclusive rights and privileges. They had no taxes to pay. In case of plunder taken from the enemy, they received their full share without any deduction, while all the others were obliged to contribute a portion of their shares for the khan. The exempts, too, were allowed various other privileges. They had the right to go into the presence of the khan at any time, without waiting, as others were obliged to do, till they obtained permission, and, what was more singular still, they were entitled to _nine_ pardons for any offenses that they might commit, so that it was only when they had committed ten misdemeanors or crimes that they were in danger of punishment The privileges which Temujin thus bestowed upon the slaves were to be continued to their descendants to the seventh generation. Temujin rewarded the slaves in this bountiful manner, partly, no doubt, out of sincere gratitude to them for having been the means, probably, of saving him and his army from destruction, and partly for effect, in order to impress upon his followers a strong conviction that any great services rendered to him or to his cause were certain to be well rewarded. Temujin now found himself at the head of a very large body of men, and his first care was to establish a settled system of discipline among them, so that they could act with regularity and order when coming into battle. He divided his army into three separate bodies. The centre was composed of his own guards, and was commanded by himself. The wings were formed of the squadrons of his confederates and allies. His plan in coming into battle was to send forward the two wings, retaining the centre as a reserve, and hold them prepared to rush in with irresistible power whenever the time should arrive at which their coming would produce the greatest effect. When every thing was thus arranged, Temujin set his army in motion, and began to advance toward the country of Vang Khan. The squadrons which composed his immense horde were so numerous that they covered all the plain.
