6.6.3

Mahmood, in the year 415, having mustered all his forces, found them to consist of 54,000 chosen horse, and 1300 elephants, disposable for foreign service. With this army he marched to Bulkh, to expel Allytuggeen from the government of Mawur-ool-Nehr, for oppressing the people, who complained of his tyranny to the King. When the chiefs of Mawur-ool-Nehr heard that the King had crossed the Jyhoon, they came with presents to meet him. Kuddur Khan, of Khootun, also paid him the compliment of a visit, and was honourably received. Mahmood prepared a great feast upon this occasion, and concluded a treaty, after which the monarchs took leave of each other, making an exchange of princely presents. Allytuggeen, seizing this opportunity, betook himself to flight, but the King of Ghizny sent a party of horse after him; after a long search he was discovered and brought to the camp, after which he was confined for life in one of the forts of India.
