Though names and details differ, it will be observed that there is evidently a common basis of truth in the accounts given by Firishtah and Nuniz. Both relate the deaths of two young princes, brothers, the subsequent murder of two other heirs to the kingdom, and the usurpation of the throne by a minister. With these remarks we turn to the more reliable portion of Firishtah's narrative. Yusuf Adil Khan proclaimed himself independent king of Bijapur in A.D. 1489. Shortly afterwards his rival, Kasim Barid, who ultimately became sovereign of the territories of Ahmadabad, in a fit of jealousy called in the aid of Vijayanagar against Bijapur, promising for reward the cession of Mudkal and Raichur, or the country between the two rivers. Narasimha collected the forces of the Hindus, crossed the Tungabhadra with a large army, and after laying waste the country seized the two cities Mudkal and Raichur, which thus once more passed into the possession of Vijayanagar. Shortly after this, probably about the year 1493 A.D., Sultan Yusuf Adil again marched to recover the lost territory and advanced to the Krishna, but falling ill he halted for two months; and Firishtah gives us the following account of what occurred. This has been already alluded to, but is now given in full: -- "In this interval Heemraaje, having settled his dissensions,[178] advanced with the young roy at the head of a great army to Roijore, which struck terror into the army of Adil Shaw, for whose recovery earnest prayers were offered up by his subjects." ... (The prayers were answered and the Sultan recovered.)
