The hill that refused to fall
Sher Shah Suri, the man who had driven the Mughal emperor Humayun out of Hindustan and built the Grand Trunk Road across the subcontinent, died at Kalinjar in 1545 from a gunpowder explosion inside his own siege camp. He had taken nearly every fort he ever looked at. Kalinjar was the exception, and it killed him before he could make it otherwise.
