"San Giorgio" ran aground in August 1911 off Naples-Posillipo; heavily damaged, she was under repair until June 1912, missing most of the Italo-Turkish War. "San Marco" supported the occupations of Benghazi and Derna, Libya during the war and bombarded the fortifications defending the entrance to the Dardanelles. She also supported the forces occupying the island of Rhodes in May 1912. In February 1913, "San Giorgio" cruised the Aegean Sea and made a port visit to Salonica, Greece, the next month. She ran aground again on 21 November in the Strait of Messina, but was only slightly damaged.
