The SS Ardena was originally constructed as an Azalea-class sloop minesweeper for the Royal Navy, designated as HMS Peony in 1915. The vessel measured approximately 262 feet 6 inches (80.01 meters) in length overall, with a beam of 33 feet (10.06 meters) and a draught of 11 feet (3.35 meters). Displacing about 1,210 long tons (1,229 metric tons), she was powered by two cylindrical boilers feeding a triple-expansion steam engine rated at 1,800 indicated horsepower, enabling a top speed of 16.5 knots (19 mph). Her armament included two 4.7-inch or 4-inch guns along with two 3-pounder anti-aircraft guns, and she carried a crew of 90 officers and ratings. Launched on 25 August 1915 from the Dumbarton shipyard of Archibald McMillan & Son and completed by October 1915, Peony was assigned to the Mediterranean Fleet. During World War I, she played a significant role in the Dardanelles evacuation in December 1915, serving as the headquarters ship for General Julian Byng during the Suvla Bay withdrawal. She also participated in operations aimed at pressuring Greece to demobilize its army after allowing German forces to occupy eastern Macedonia. By mid-1917, Peony was part of the Eastern Mediterranean Squadron, later the Aegean Squadron, and was equipped to support anti-submarine efforts with seaplanes, operating out of Leros and Mudros to detect German U-boat bases and conduct anti-submarine patrols. Following the war, she was listed with the 12th Sloop Flotilla based at Malta in 1919. The vessel was sold in August 1919, subsequently acquired by the London and South Western Railway, and reconstructed as a passenger ferry named Ardena in 1920. She served routes to Cherbourg and Caen until 1934, later passing to Navigation Constantine Toyias of Piraeus. During World War II, Ardena was involved in convoy operations and was damaged in April 1941 during a collision with the Greek destroyer Leon, which also resulted in the destruction of two officers. She was later sunk by the Luftwaffe in 1941, was salvaged by German forces, and eventually was lost again in September 1943 after hitting a mine off Argostoli while transporting Italian prisoners of war, resulting in the deaths of 720 prisoners. Her service life reflects her transition from a wartime minesweeper to a civilian passenger vessel, and finally, a wartime casualty in the Mediterranean theater.
