Question: What country owns the islands that the fleet knew Spanish galleys were in? Passage:In mid-1540 the Barbary pirate Ali Hamet, a Sardinian renegade in service of the Ottoman Empire, formed a small fleet at Algiers, as ordered by Admiral Hayreddin Barbarossa. He assembled three galleys, five galliots, six fustas and two brigantines, manned by 900 captive oarsmen and 2,000 Turkish soldiers and Valencian Moriscos under the command of General Caramani, a former slave in the Spanish galleys. In August, knowing that Spanish galleys were in the Balearic Islands, the fleet set sail to the western waters of the Alboran Sea. A few days later a thousand soldiers from the galleys landed on the beach of Gibraltar and attacked the village. Although they failed to capture the well-protected castle, 73 civilians were taken prisoner, 40 vessels moored in the port were plundered, and a galley under construction (owned by Don Alvaro de Bazan the Elder) was burnt. The prisoners were carried off to Velez de la Gomera, on the Moroccan coast, where they were imprisoned until their release following a payment of 7,000 ducats.
