Firishta's History (Gulshan-i Ibrāhīmī) 6.4.4

6.4.4

In the year 404, Mahmood marched his army against the fort of Nindoona, situated on the mountains of Balnat, then in the possession of the Raja of Lahore. Anundpal had lately died, and his son, Jeipal the Second, had succeeded to the government. When the grandson of Jeipal saw that he could not oppose the King in the field, he drew off his army towards Kashmeer, leaving troops for the defence of his capital. Mahmood immediately invested it, and by mining and other modes of attack, put the garrison under the necessity of capitulating. The King having granted to the besieged their lives took every thing of value out of the place, and appointing a new governor moved without delay towards Kashmeer, on which the Raja of Lahore, abandoning that province, fled to the hills. Mahmood plundered Kashmeer, and, having forced the inhabitants to acknowledge the Prophet, returned with rich spoils to his capital.
