According to one legend, in the year 1489 the Ahmadnagar Sultanate sent its Admiral Piram Khan (of Ethiopian descent) with orders to capture the Murud-Janjira castle from Ram Patil. Owing to the castle's fortifications, the Admiral could not attack conventionally.
He and his team disguised themselves as merchants and asked Ram Patil to safeguard their three hundred large boxes containing silks and wines from Surat. As thanks, Piram Khan threw a party with wine. Once Ram Patil and his soldiers were intoxicated, Piram Khan opened the boxes, which contained his soldiers, and used the opportunity to capture the castle and the island on which it stands.
