In August 1509, near the mouth of the Tiber River in central Italy, he engaged two Papal galleys under the command of Baldassarre di Biassa and captured one of them. In September 1510, with a squadron of nine fustas, he landed at the island of Andros, which was then under Venetian control, and took dozens of captives who were later ransomed. Later in September, with a squadron of six fustas, he landed at the Genoese-controlled island of Chios and forced the governor to pay 100,000 aspri (silver coins) in return for the release of the island.
