Haidar the Mughal and Dustat Kashmiri also remained at Agra, and were kindly treated. Shir Khan waxed bold at the success of these hypocrisies, and towards the close of the year aforesaid reached the bank of the Ganges, and despatching a force under his son Qutb Khan, sent him across [the Ganges] against Kalpi and Itawa. Qasim Husain Sultan Usbeg, in concert with Yadgar Nasir Mirza and Iskandar Sultan, after a fight in the vicinity of Kalpi put to death the son of Shir Khan with a large number of his following, sending their heads to Agra. Humayun started to oppose Shir Khan with a large force composed of some hundred thousand cavalry, and crossing the river of Qanauj encamped in face of his enemy for the space of one month. The army of Shir Khan did not comprise in all more than five thousand cavalry. It was under such circumstances that Muhammad Sultan Mirza and his son fled a second time from the king, and the reinforcements of Mirza Kamran also took flight to Lahor, and the Mughals of the King's army were scattered in all directions. The rains now came on, and inasmuch as the camp of Humayun's army was on low-lying ground, he desired to march from there and encamp on the high ground. At this very time Shir Khan drew up his troops, and came out to give battle. This engagement took place on the day of the 'Ashura, the 10th of Muharram 947 H., and a chronogram was found for it in the words Kharabi-i-mulk-i-Dihli.
