Siege of Dwarasamudra

In late 1310, the Delhi Sultanate ruler Alauddin Khalji sent his general Malik Kafur on an expedition to the southernmost regions of India. In February 1311, Malik Kafur besieged the Hoysala capital Dwarasamudra, and the defending ruler Veera Ballala III surrendered without much resistance. Ballala agreed to pay the Delhi Sultanate an annual tribute, and surrendered a great amount of wealth, elephants and horses.

 * Invasion of Dvarasamudra. — On Sunday, the 22nd of Ramzan, Malik Kafur held a council of war. Apparently as a result of a resolution he took with him a select body of cavalry, and appeared before the fort of Dhur Samundar on the fifth of Shawwal ' after a difficult march of twelve days over hills and valleys and thorny forests.' Seeing the destructive character of the invasion, the ruler Vira Ballala III having ascertained the strength of the Muhammadan army sent agents to propose peace, though Vira Pandya had despatched an army to assist him. Malik Kafur is stated to have sent the reply ' that he was sent with the object of converting him to Muhammadanism, or of making him zimmi (one who could enjoy the same political privileges as the Muhammadans on payment of Jiziya) and subject to pay tax, or of slaying him, if neither of these terms were assented to.' The Rai agreed to surrender all his property ' except his sacred thread ' and on Friday the sixth of Shawwal, six elephants were sent accompanied by three plenipotentiaries. The next day some horses followed and on the Sunday following he is himself said to have paid a visit to the Commander-in-Chief and surrendered all his treasures, having spent a whole night in taking them out. Malik Kafur remained twelve days in that city, which,  according to Amir Khusru, is four months distant from  Delhi, to which he sent the captured elephants.
