This ceremony was long remembered in the army, all those who had been present and had taken part in it cherishing the recollection of it with pride and pleasure; and long afterward, when Temujin had attained to the height of his power and glory, his generals considered their having been present at this first solemn league and covenant as conferring upon them a sort of title of nobility, by which they and their descendants were to be distinguished forever above all those whose adhesion to the cause of the conqueror dated from a later time. By this time Temujin began to feel quite strong. He moved on with his army till he came to the borders of a lake which was not a great way from Vang Khan's dominions. Here he encamped, and, before proceeding any farther, he determined to try the effect, upon the mind of Vang Khan, of a letter of expostulation and remonstrance; so he wrote to him, substantially, as follows: "A great many years ago, in the time of my father, when you were driven from your throne by your enemies, my father came to your aid, defeated your enemies, and restored you. "At a later time, after I had come into your dominions, your brother conspired against you with the Markats and the Naymans. I defeated them, and helped you to recover your power. When you were reduced to great distress, I shared with you my flocks and every thing that I had. "At another time, when you were in circumstances of great danger and distress, you sent to me to ask that my four intrepids might go and rescue you. I sent them according to your request, and they delivered you from a most imminent danger. They helped you to conquer your enemies, and to recover an immense booty from them. "In many other instances, when the khans have combined against you, I have given you most effectual aid in subduing them. "How is it, then, after receiving all these benefits from me for a period of so many years, that you form plans to destroy me in so base and treacherous a manner?" This letter seems to have produced some impression upon Vang Khan's mind; but he was now, it seems, so much under the influence of Sankum and Yemuka that he could decide nothing for himself. He sent the letter to Sankum to ask him what answer should be returned. But Sankum, in addition to his former feelings of envy and jealousy against Temujin, was now irritated and angry in consequence of the wound that he had received, and determined to have his revenge. He would not hear of any accommodation.
