Firishta's History (Gulshan-i Ibrāhīmī) 37.6.1

37.6.1

Alla-ood-Deen about this time sent an army by the way of Bengal to reduce the fort of Wurungole in Tulingana, while he himself marched towards Chittoor, a place never before attacked by the troops of the Mahomedans. After a siege of six months, Chittoor was reduced in the year 1303, and the government of it conferred on the King's eldest son, the Prince Khizr Khan, after whom it was called Khizrabad. At the same time, the King bestowed upon Khizr Khan regal dignities, and he was publicly proclaimed successor to the throne. Intelligence of these distant expeditions becoming known in Mawur-ool-Nehr, Toorghay Khan, the Mogul chief who had distinguished himself formerly against Zuffir Khan, thinking that Alla-ood-Deen would for a long time be absent, seized the opportunity of invading Hindoostan. The King, hearing of this dangerous inroad, abandoned, for the present, his designs on the Deccan, and caused his army to return to Dehly. Toorghay Khan, with twelve tomans of Mogul horse, amounting to 120,000 men, reached the capital, and encamped on the banks of the Jumna. The cavalry of the Indian army being absent on the expedition to Wurungole, the King was in no condition to face the enemy on equal terms, and therefore contented himself with entrenching his infantry on the plain beyond the suburbs, till he could collect the forces of the distant districts.
