The Rashīdī History 3.4.9

3.4.9

He had learned from his previous incursion into that country, while in the service of the Khan of Kashghar, the value of its position and resources, and calculated that, with a reasonable force, he would require only two months to subjugate it and make it a suitable asylum for the Emperor and his family, together, if necessary, with the remains of the Chaghatai army. Shir Shah, on the other hand, with the wheeled carriages and the artillery, on which his strength mainly depended, would not, the Mirza reckoned, be able to reach the outer hills in less than four months, and his troops would be exhausted by the effort. Though these plans were not taken advantage of by Humayun (who continued his retreat to the Indus), he permitted them to be put into practice by Mirza Haidar. The Mirza was given a small body of troops, and was sent forward from Lahore to join the Kashmiri chiefs, in whose company he was to enter the hills of their country, and to be followed, at intervals, by two of Humayun's officers, called respectively Iskandar Tupchi and Khwaja Kalan. When all had assembled above Jhilam, and the force had begun to ascend the passes leading to the valley of Kashmir, dissensions arose among the commanders.
