In his journeys about the country Temujin sometimes took his wives with him, and sometimes he left them temporarily in some place of supposed security. Toward the end of the second year Purta was again about to become a mother, and Temujin, who at that time had occasion to go off on some military expedition, fearing that the fatigue and exposure would be more than she could well bear, left her at home. While he was gone a troop of horsemen, from a tribe of his enemies, came suddenly into the district on a marauding expedition. They overpowered the troops Temujin had left to guard the place, and seized and carried off every thing that they could find that was valuable. They made prisoner of Purta, too, and carried her away a captive. The plunder they divided among themselves, but Purta they sent as a present to a certain khan who reigned over a neighboring country, and whose favor they wished to secure. The name of this chieftain was Vang Khan. As this Vang Khan figures somewhat conspicuously in the subsequent history of Temujin, a full account of him will be given in the next chapter. All that is necessary to say here is, that the intention of the captors of Purta, in sending her to him as a present, was that he should make her his wife. It was the custom of these khans to have as many wives as they could obtain, so that when prisoners of high rank were taken in war, if there were any young and beautiful women among them, they were considered as charming presents to send to any great prince or potentate near, whom the captors were desirous of pleasing. It made no difference, in such cases, whether the person who was to receive the present were young or old. Sometimes the older he was the more highly he would prize such a gift. Vang Khan, it happened, was old. He was old enough to be Temujin's father. Indeed, he had been in the habit of calling Temujin his son. He had been in alliance with Yezonkai, Temujin's father, some years before, when Temujin was quite a boy, and it was at that time that he began to call him his son. [Illustration: PURTA IN THE TENT OF VANG KHAN.] Accordingly, when Purta was brought to him by the messengers who had been sent in charge of her, and presented to him in his tent, he said, "She is very beautiful, but I can not take her for my wife, for she is the wife of my son. I can not marry the wife of my son." Vang Khan, however, received Purta under his charge, gave her a place in his household, and took good care of her.
