Then Khaled accomplished all that he had spoken of, and much more, for he drove the scattered force of the enemy before him, overtaking all at last and slaying all whom he overtook as far as Zulfah which is by the narrow end of the Nefud. Here he rested a short time, and then quickly crossing the sand, he entered the country called Kasim which is subject to the Shammars. Here he was told by a woman who had been taken that the Shammars were coming with a new army against him out of Haïl. He therefore hid his host in a pass of the hills just above the plain, and sent down a few Bedouins to encamp at the foot of the mountains, bidding them call themselves Shammars and make a show of being friendly to the enemy. So when the army of the Shammars reached the foot of the hills, they saw the tents and only one or two camels, and Khaled's Bedouins came out and welcomed them, and told them that Khaled was still crossing the Nefud, and that if they made haste through the hills they might come upon him unawares and at an advantage as he began to ascend. Thereupon the enemy rejoiced and entered the pass in haste, after filling their water-skins.
When they were in the midst of the hills, Khaled and his army sprang up from the ambush and fell upon them, and utterly destroyed them, taking all their horses and camels and arms; after which he went down into the plain and laid waste the country about Haïl. He took the city as the Shammars had taken Riad. For he himself got upon the wall at night, with the strongest and the bravest of his followers, and slew the guards and opened the gate just before the dawn. But there was no Khaled in Haïl to rally the soldiers and give them heart to turn and make a stand in the streets.
Khaled then entered the palace and took the Sultan of Shammar alive, not suffering him to be hurt, for he wished to bring him to Riad. This Sultan was a man of middle age, having only one eye, and also otherwise ill-favoured, besides being cowardly and fat. So Khaled ordered that he should be put into a litter, and the litter into a cage, and the cage slung between two camels. But he commanded that the women of the harem should be well treated and brought before him, that he might see them, intending to bring back the most beautiful of them as presents to his father-in-law.
