The SS Patroclus was a British steam turbine passenger and refrigerated cargo liner launched in 1923 by Scotts Shipbuilding and Engineering Company in Greenock, Scotland. She was the third vessel bearing this name and was part of a series of four sister ships built for Alfred Holt and Company of Liverpool, which owned Blue Funnel Line and other shipping interests. Her sister ships included Sarpedon, Hector, and Antenor, all named after characters from Homer’s Iliad. Measuring approximately 498.8 feet (152.0 meters) in length with a beam of 62.3 feet (19.0 meters) and a depth of 26.4 feet (8.0 meters), Patroclus featured a counter stern, a slightly raked stem, one funnel, and two masts. Designed primarily for passenger service to the Far East, she accommodated 155 first-class passengers, although her owners did not expect passenger revenue to be the primary profit source. Her gross register tonnage was 11,314 GRT, with a net tonnage of 6,912 NRT. Powered by two steam turbines driving twin screws via single-reduction gearing, she could reach a service speed of 15 knots. By 1934, she was equipped with wireless direction-finding capabilities. During the Second World War, the Admiralty requisitioned Patroclus on 12 September 1939, converting her into an armed merchant cruiser (HMS Patroclus). Her armament included six BL 6-inch Mk XII naval guns and two QF 3-inch anti-aircraft guns. She served on various patrols, including the Northern Patrol, South Atlantic Station, and Western Patrol. Patroclus’s wartime service ended tragically when she was sunk by the German U-boat U-99 in November 1940. During an engagement west of Ireland, U-99 torpedoed her multiple times and hit her with a deck gun, ultimately breaking her back and causing her stern to capsized and her bow to slowly sink. Of her crew, 76 were lost, including her captain, Captain Gerald Wynter. Rescue efforts by the destroyer HMS Beagle saved 230 survivors, while HMS Hesperus arrived to drive U-99 away. The sinking marked a significant loss in her wartime service but underscored her role as part of the Allied maritime efforts during the war.
