In 1910, "Weissenburg" was sold to the Ottoman Empire and renamed Turgut Reis, after the famous 16th century Turkish admiral. The ship saw heavy service during the Balkan Wars, primarily providing artillery support to Ottoman ground forces. She also took part in two naval engagements with the Greek Navy—the Battle of Elli in December 1912, and the Battle of Lemnos the following month. Both battles were defeats for the Ottoman Navy. After the Ottoman Empire entered World War I, she supported the fortresses protecting the Dardanelles through mid-1915, and was decommissioned from August 1915 to the end of the war. She served as a training ship from 1924 to 1933, and a barracks ship until 1950, when she was broken up.
