In the year 956, Peer Mahomed Khan, the ruler of the Oozbuks, having made some incursions into Hoomayoon's dominions, the latter marched towards Bulkh to oppose them. On this occasion both Kamran Mirza and Askurry Mirza, who accompanied him, began to excite disaffection amongst his troops; but Hoomayoon took no effectual steps to prevent their designs. Arriving in the environs of Bulkh, Shah Mahomed Sooltan Oozbuk opposed Hoomayoon with three thousand horse, and checked his progress. On the second day the Oozbuks, being joined by Peer Mahomed Khan, Abdool Azeez Khan, the son of Abdoolla Khan Oozbuk, and the Princes of Khoozar, mustered thirty thousand horse, with which they gave battle to Hoomayoon. Sooliman Mirza, Hindal Mirza, and Hajy Mahomed Koka opposed and defeated the advanced parties of the Oozbuks, and even pressed Peer Mahomed Khan so severely, that he was compelled to retreat within the walls of Bulkh.
