It was a very beautiful city, which was ruled by old Sultan, who had a beautiful daughter. But suddenly the trouble came from the step, sweeping away everything in its way.
Inhabitants courageously fought against them, but day after day, all stocks were eaten famine. People fed one bull to dump with remaining grain from the royal granaries and released outside the city wall. Kalmyks also ranked raging hunger, caught and stabbed it, and when they saw that its stomach was stuffed with selected grains, military commanders demanded to lift the siege. Because if they so fed cattle, then didn’t anything, and therefore, the city unapproachable. But daughter of Sultan – Guldursun fell in love with the leader of Kalmiks, sent him letter. There she described the true situation. Kalmyks remained; the city fellwas burned and looted. And when traitor led to Kalmyk leader, he looked at her and said, “If she had betrayed his father’s enemies and his people because of her feelings, what can wait for me when someone else will awaken her heart? Tie it to the tails of wild stallions, anyone else she could not betray. ”
Terrible death befell perfidious beauty, but since this place has been called in her honor – Guldursun.
