At one time Genghis Khan sent his son Jughi with a large detachment to besiege and take a certain town named Saganak. As soon as Jughi arrived before the place, he sent in a flag of truce to call upon the people of the town to surrender, promising, at the same time, to treat them kindly if they would do so. The bearer of the flag was a Mohammedan named Hassan. Jughi probably thought that the message would be better received by the people of the town if brought to them by one of their own countrymen, but he made a great mistake in this. The people, instead of being pleased with the messenger because he was a Mohammedan, were very much exasperated against him. They considered him a renegade and a traitor; and, although the governor had solemnly promised that he should be allowed to go and come in safety, so great a tumult arose that the governor found it impossible to protect him, and the poor man was torn to pieces by the mob. Jughi immediately assaulted the town with all his force, and as soon as he got possession of it he slaughtered without mercy all the officers and soldiers of the garrison, and killed also about one half of the inhabitants, in order to avenge the death of his murdered messenger. He also caused a handsome monument to be erected to his memory in the principal square of the town. Jughi treated the inhabitants of every town that dared to resist with extreme severity, while those that yielded at once were, in some degree, spared and protected. The consequence of this policy was that the people of many of the towns surrendered without attempting to defend themselves at all. In one case the magistrates and other principal inhabitants of a town came out to meet him a distance of two days' journey from them, bringing with them the keys of the town, and a great quantity of magnificent presents, all of which they laid at the conqueror's feet, and implored his mercy.
