[4] According to the 14th century chronicler Ziauddin Barani, this Delhi army had managed to reach Warangal, but decided to return because the rainy season had started.
[5] The 16th century chronicler Firishta states that this army was ordered to reach Warangal via Bengal, even though a shorter route passed through central India.
Historian Banarsi Prasad Saksena suggests that this decision might have been taken because Alauddin had not yet conquered the Malwa region in central India.
[2] However, historian Kishori Saran Lal theorizes that Alauddin wanted to conquer Bengal, which had been a part of the Delhi Sultanate under the Mamluk dynasty, but had since become independent.
[9] According to the Delhi courtier Amir Khusrau, Alauddin ordered Malik Kafur to invade the Kakatiya kingdom on 31 October 1309.
[10] As the Kakatiya territory was unfamiliar to the Delhi forces, Alauddin recommended lenient treatment of the troops, so as to avoid any resentment or revolt.
He advised Kafur not to remain in Kakatiya territory for long, and to accept a tribute from Prataparudra instead of bringing him to Delhi as a prisoner.
[2] Alauddin made arrangements for rapid communication of news about the expedition by establishing thanas (posts) all along the route from Tilpat near Delhi to the army's current position.
On the route connecting Devagiri to Warangal, he established markets, where Malik Kafur's soldiers could buy things at the rates fixed by Alauddin.
[13] According to Khusrau, before entering the Kakatiya territory, the Delhi army halted at Bavagarh (misread as "Basiragarh" or "Bijainagar" by some translators).
It has been identified with modern Wairagarh in Gadchiroli district; the names of the rivers in Khusrau's writings appear to be corrupt: at least one of them must be Wainganga or one of its tributaries.
[16] The same day Malik Kafur reached Bavagarh, he led a cavalry unit to besiege Sabar, a fort located within the Kakatiya frontier region.
[15] Khusrau's account suggests that this was a surprise attack for the defenders: faced with a certain defeat, some of them committed suicide with their wives and children in a jauhar fire.
The Delhi commander Nasir-ul-mulk Siraj-ud-daula Khwaja Haji assigned his soldiers in such a way that the Warangal fort was completely surrounded.
Every tuman (unit of 10,000 soldiers) was assigned a piece of land around the fort, and a strong wooden wall was constructed around the tents to secure them against attacks from the countryside.
[16] One night, the Kakatiya governor Vinayaka Deva (also called Banik Deo or Manik-deva) led a sortie with a 1000-strong cavalry.
During the night of 13 February, Malik Kafur had his soldiers build tall ladders to scale the ramparts for a decisive assault.
[21] According to Barani's account, once Alauddin did not receive any updates on the siege for over a month (presumably because the communication arrangements made by him had been disrupted by the enemy activities).
[22] The Muslim chroniclers state that Prataparudra sent Malik Kafur a golden statue of himself with a chain round its neck to symbolize his unconditional surrender.
He also jokingly prayed to God to keep Prataparudra alive till the day of the Last Judgment, because the Kakatiya ruler promised to pay a huge annual tribute to the Delhi Sultanate.
Khusrau quotes a messenger of Prataparudra as saying that one of the surrendered precious stones was "unrivaled in the world": the wise philosophers refused to believe that such a substance could even exist.
The 14th century chronicler Isami states that Malik Kafur also gifted Prataparudra a "robe of honour embroidered with jewels" after the peace treaty.
[24] On 23 June 1310, Malik Kafur formally presented the loot from Warangal to Sultan Alauddin in a darbar organized at Chabutra-i Nasiri near the Badaun Gate.
After the fall of the Khalji dynasty, Prataparudra was decisively defeated by an expedition sent in 1323 by the Delhi Sultanate's new ruler Ghiyath al-Din Tughluq.
