In spring 1533, the Ottoman Emperor Suleiman the Magnificent sent 60 galleys to retake the city. They blockaded the harbour, but they were defeated by Admiral Doria of the Genoese navy, highlighting the weakness of the Ottoman Navy at that time.[1] An Ottoman land army however was successful in laying a siege around the city, forcing its surrender on 1 April 1534. The weakened Spanish garrison was allowed to leave the city unharmed.[2]
