Analysis of information sources in references of the Wikipedia article "Sher Shah Suri" in English language version.
the Raja of Kālinjar, who sympathized with Humāyūn, was still defiant. Sher Shah blockaded this fort but failed it to storm it. The Rãjpūts there fought back to back for seven months. Finally, however, when mines had been laid, a lofty tower for mounting a battery had been erected, and covered approaches were ready, the attack was launched. Lighted hand-grenades were thrown into the fort. One grenade suddenly struck the wall and, rebounding into a heap of hand-grenades, exploded. Immediately the whole ammunition dump blew up. Sher Shāh himself was very badly burned, and although the fort was stormed and the Rājpūts overpowered, he died, with his ambitions unrealized.
