Flotilla and based at Cattaro, though she was too slow to operate with the newer s that carried out the bulk of offensive operations. Battle of the Strait of Otranto During the Battle of the Strait of Otranto on 15 May 1917, Sankt Georg was deployed to support the three light cruisers commanded by Captain Miklós Horthy—, , and —that had raided the Otranto Barrage in the southern Adriatic. After completing their attack on the Allied defenses, the three cruisers turned north before being engaged by British and Italian warships, including the British cruiser . Horthy called for reinforcements, which led Sankt Georg to sortie, accompanied by two destroyers and four torpedo boats.

She soon broke down but at the same time, shortly after 11:00, most of the Allied warships broke off the engagement, having spotted smoke on the horizon from Austro-Hungarian reinforcements.

Heavy Austro-Hungarian fire drove them off and by 12:07 they had retreated with the rest of the Anglo-Italian ships. Sankt Georg arrived and Saida took Novara under tow for the voyage back to port. The four cruisers assembled in line-ahead formation, with Sankt Georg the last vessel in the line, to cover the other three ships. Later in the afternoon, the old coastal defense ship and three more torpedo boats joined the ships to strengthen the escort. Cattaro Mutiny By early 1918, the long periods of inactivity had begun to wear on the crews of several warships at Cattaro, including Sankt Georg. At this time, Sankt Georg was the flagship of the Cruiser Flotilla, commanded by Konteradmiral (Rear Admiral) Alexander Hansa. On 1 February, the Cattaro Mutiny broke out, starting aboard Sankt Georg. An enlisted man shot the ship's executive officer in the head, badly injuring him, when mutineers seized control of the ship. They then rapidly gained control of Kaiser Karl VI and most of the other major warships in the harbor. There was some resistance to the mutiny by crewmembers; the wireless operators aboard
