The Second Battle of Durazzo, or the Bombardment of Durazzo was a naval battle fought in the Adriatic Sea during the First World War. A large allied fleet led by the Regia Marina attacked the enemy-held port at Durazzo, Albania. The fleet destroyed the Austro-Hungarian shore defenses and skirmished with a small naval force. Allied forces involved primarily were Italian though British, American and Australian warships also participated. It was the largest naval battle the United States participated in during the war.
