In 1256 Ulugh Khan Balban carried on devastating warfare in Sirmur, and ‘so many of the rebellious Hindus were killed that numbers cannot be computed or described.’ Ranthambhor was attacked in 1259 and ‘many of its valiant fighting men were sent to hell.’ In the punitive expedition to Mewat (1260) ‘numberless Hindus perished under the merciless swords of the soldiers of Islam.’ In the same year 12,000 men, women and children were put to the sword in Hariyana.

Ulugh Khan Balban marched with a large force on a campaign in the region of Ranthambhor, Mewat and Siwalik. He made a proclamation that a soldier who brought a live captive would be rewarded with two silver tankahs and one who brought the head of a dead one would get one silver tankah. Soon three to four hundred living and dead were brought to his presence.
