"Thereafter, Malik Kafur set out for Warangal, which he reached in 1310. It was then ruled by the Kakatiya king, Prataprudradeva. Amir Khusrau (1253-1325) provided details of the siege of the double-walled city, The wall of Arangal was made of mud, but so strong that a spear of steel could not pierce it: and if a ball from a western catapult were to strike against it, it would rebound like a nut with which children play with... Orders were issued that every man should erect behind his own tent a kath-gar, that is a wooden defence. The trees were cut with axes and felled, notwithstanding their groans: and the Hindus, who worship trees, could not at that time come to the rescue of their idols, so that every cursed tree which was in that capital of idolatry was cut down to the roots; and clever carpenters applied the sharp iron to shape the blocks, so that a wooden fortress was drawn around the army of such stability, that if fire had rained from heaven their camp would have been unscathed...The Naib Amir gave daily orders to attack the chiefs of Laddar Deo (Prataprudradeva), and he also ordered the ‘western stoneballs’ to be thrown at the wall from every direction’ to demolish it, and reduce it to powder... The Malik took the entire wealth of the Rai which was brought, and threatened a general massacre, if it should be found that the Rai had reserved anything for himself. An engagement was then entered into that the Rai should send jizya annually to Dehli. The Malik left Arangal on the 16th of Shawwal (March 1310 AD) with all his booty, and a thousand animals groaned under the weight of the treasure”."
