The Bijapur commander Randaula Khan sent a force led by Afzal Khan to capture Sira. Kasturi Ranga Nayaka, the commander of Sira, came out of the fort to negotiate with Afzal Khan, but Afzal Khan treacherously killed him. The defenders closed the fort gates before Afzal Khan could enter the fort, but Afzal Khan's contingent was soon reinforced by the main Bijapur army led by Randaula Khan. The Bijapur army captured the fort, and handed it over to Kenge Nayaka, while sending the captured wealth to Bijapur. Kenge Nayaka subsequently switched his allegiance to Bangalore, but then re-joined Bijapur, and convinced the Bangalore ruler Kempe Gowda to surrender his fort to Bijapur.
