Explanation:

 Hammir, the Chahamana (Chauhan) king of Ranthambore, had granted asylum to some Mongol rebels from Delhi in 1299. He refused requests to either kill these rebels or hand them over to Alauddin, resulting in an invasion from Delhi.Alauddin then himself took control of the operations at Ranthambore. He ordered the construction of a mound to scale its walls. After a long siege, the defenders suffered from a famine and defections. Facing a desperate situation, in July 1301, Hammir and his loyal companions came out of the fort, and fought to death. His wives, daughters and other female relatives committed Jauhar (mass self-immolation). Alauddin captured the fort, and appointed Ulugh Khan as its governor.
