He accordingly took with him a few favorites of his immediate family and a small body of troops, and commenced his journey--a journey which was considered by all the people as a base and ignoble flight. He involved himself in endless troubles by this step. A revolt broke out on the way among the guards who accompanied him. One of the generals who headed the revolt sent a messenger to Genghis Khan informing him of the emperor's abandonment of his capital, and offering to go over, with all the troops under his command, to the service of Genghis Khan if Genghis Khan would receive him. When Genghis Khan heard thus of the retreat of the emperor from his capital, he was, or pretended to be, much incensed. He considered the proceeding as in some sense an act of hostility against himself, and, as such, an infraction of the treaty and a renewal of the war. So he immediately ordered one of his leading generals--a certain chieftain named Mingan--to proceed southward at the head of a large army and lay siege to Yen-king again. The old emperor, who seems now to have lost all spirit, and to have given himself up entirely to despondency and fear, was greatly alarmed for the safety of his son the prince, whom he had left in command at Yen-king. He immediately sent orders to his son to leave the city and come to him. The departure of the prince, in obedience to these orders, of course threw an additional gloom over the city, and excited still more the general discontent which the emperor's conduct had awakened. The prince, on his departure, left two generals in command of the garrison. Their names were Wan-yen and Mon-yen. They were left to defend the city as well as they could from the army of Monguls under Mingan, which was now rapidly drawing near. The generals were greatly embarrassed and perplexed with the difficulties of their situation. The means of defense at their disposal were wholly inadequate, and they knew not what to do. At length one of them, Wan-yen, proposed to the other that they should kill themselves. This Mon-yen refused to do. Mon-yen was the commander on whom the troops chiefly relied, and he considered suicide a mode of deserting one's post scarcely less dishonorable than any other. He said that his duty was to stand by his troops, and, if he could not defend them where they were, to endeavor to draw them away, while there was an opportunity, to a place of safety. So Wan-yen, finding his proposal rejected, went away in a rage. He retired to his apartment, and wrote a dispatch to the emperor, in which he explained the desperate condition of affairs, and the impossibility of saving the city, and in the end declared himself deserving of death for not being able to accomplish the work which his majesty had assigned to him. He enveloped and sealed this dispatch, and then, calling his domestics together, he divided among them, in a very calm and composed manner, all his personal effects, and then took leave of them and dismissed them.
