Firishta's History (Gulshan-i Ibrāhīmī) 6.3.4

6.3.4

The King, in his zeal to propagate the faith, now marched against the Hindoos of Nagrakote, breaking down their idols and razing their temples. The fort, at that time denominated the Fort of Bheem, was closely invested by the Mahomedans, who had first laid waste the country around it with fire and sword. Bheem was built by a prince of the same name, on the top of a steep mountain, where the Hindoos, on account of its strength, had deposited the wealth consecrated to their idols by all the neighbouring kingdoms; so that in this fort there is supposed to have been a greater quantity of gold, silver, precious stones, and pearls, than was ever collected in the royal treasury of any prince on earth. Mahmood invested the place with such expedition, that the Hindoos had no time to throw in troops for its defence. The greater part of the garrison was before in the field, and those within consisted, for the most part, of priests, who, having little inclination to the bloody business of war, made overtures to capitulate; and on the third day Mahmood became master of this strong citadel without opposition or bloodshed.
