The war was probably undertaken in revenge for a cruel massacre of
Muhammadans which took place in this Year A.D. 1469, according to
Barros.[154] At this period the coast trade was altogether in the hands
of the Muhammadans, and they used to import large numbers of horses,
principally for the use of the great contending armies in the Dakhan
and Vijayanagar. The Hindu king depended on this supply to a large
extent. In 1469 the Moors at Batecala (Bhatkal) having sold horses
to the "Moors of Decan," the king of Vijayanagar ordered his vassal
at Onor (Honawar) "to kill all those Moors as far as possible, and
frighten the rest away." The result of this was a terrible massacre, in
which 10,000 Musulmans lost their lives. The survivors fled and settled
themselves at Goa, thus founding the city that afterwards became
the capital of Portuguese India. Nuniz alludes to the loss of "Goa,
Chaull, and Dabull" by Vijayanagar in the reign of "Verupaca."[155]
(Purchas states that the massacre took place in 1479 A.D.)

Shortly afterwards there arose to power under the Sultan Muhammad
one Yusuf Adil Khan, a slave, who before long grew to such power
that he overthrew the Bahmani dynasty, and became himself the first
independent sovereign of Bijapur -- the first "Adil Shah." In 1470,
says the BURHAN-I MAASIR, the Sultan took Rajahmundry and Kondavid from
the king of Orissa. An inscription at Kondapalle, a fine hill-fort
beautifully situated on a range of hills, gives the date as 1470 or
1471; my copy is imperfect.

Firishtah tells us that --

"In the year 877 (A.D. 1472 -- 73) Perkna, roy of the fortress of
Balgoan, at the instigation of the prince of Beejanuggur, marched
