The SS Arcadian was an early 20th-century ocean liner with a notable service history spanning passenger transport, military use, and maritime innovation. Originally launched in 1899 in Barrow-in-Furness by Vickers, Sons & Maxim Ltd, she was initially named Ortona. This vessel was the last ship built by Pacific Steam for the London-to-Australia route. She was registered in Liverpool and made her maiden voyage on 24 November 1899, operating in a joint service with the Orient Steam Navigation Company. The ship accommodated 620 passengers across three classes—140 first, 180 second, and 300 third class. In December 1902, Ortona was tasked with returning troops to the UK following the Second Boer War. In May 1906, she was sold to the Royal Mail Steam Packet Company (RMSP), which renamed her Arcadian in September 1910 to fit its naming convention of starting with "A." The vessel was subsequently employed on various routes, including the Australia service, and notably transported the "All Golds" rugby team from Australia to France in 1907. In 1910, she was converted at Harland & Wolff in Belfast into a cruise ship with a capacity of 320 passengers and a gross tonnage of 8,939. Her first world cruise commenced in January 1912, making her the largest dedicated cruise ship at that time. By 1914, she was equipped with Marconi wireless telegraphy, bearing the call sign MJR. During World War I, the Admiralty chartered Arcadian in February 1915. She served as a headquarters ship at Gallipoli and later as a troop transport in the Mediterranean. Her service ended tragically on 15 April 1917 when she was torpedoed and sunk by the German submarine SM UC-74 near Milos, Greece, resulting in the loss of 279 lives. The sinking occurred shortly after a boat drill, and some of her crew and passengers, including the notable bacteriologist Sir Marc Armand Ruffer, perished. The wreck of SS Arcadian was discovered in 2024 southeast of Sifnos at a depth of 163 meters, marking the vessel’s final resting place in maritime history.
