The SS Monrovia was a substantial cargo vessel constructed in 1943 by Lithgows Ltd in Glasgow, Scotland, with yard number 981. She measured 432 feet 7 inches (131.85 meters) in length, with a beam of 56 feet 2 inches (17.12 meters), and a depth of 34 feet 2 inches (10.41 meters). Her draught was 26 feet 3 inches (8.00 meters). The ship had a gross register tonnage (GRT) of 7,067, a net register tonnage (NRT) of 4,808, and a deadweight tonnage (DWT) of approximately 9,950 tons. Propelled by a triple expansion steam engine built by Rankin & Blackmore of Glasgow, the vessel drove a single screw propeller. The engine cylinders measured 25.5 inches (65 cm), 37.5 inches (95 cm), and 68 inches (170 cm) in diameter, with a stroke of 48 inches (120 cm). Launched on 8 April 1943 and completed by May of that year, she was initially named Empire Falstaff and registered in Greenock, managed by Gibbs & Co Ltd. During World War II, she participated in numerous convoy operations across the Atlantic and Mediterranean, carrying essential cargo such as iron ore, lumber, cotton, and onions. Her service included voyages from the UK to North Africa, the Mediterranean, and the United States, often joining convoys like KMS, GUS, SL, and others, reflecting her active wartime role. In 1945, she was transferred to the French government and renamed Commandant Mantelet, later becoming Commandant le Bilboul in 1954 after sale to Société Navale Delmas Vieljeux. That same year, she was sold to Eastern Shipping Corporation of Monrovia, Liberia, and renamed Monrovia, with the code letters ELOF. Her maritime career ended in 1959 when she was involved in a collision with the Royalston on Lake Huron, approximately 11 nautical miles north of Thunder Bay Island, Michigan. During foggy conditions, she was rammed and sank while en route from Antwerp to Chicago. Her crew survived the incident, and her wreck remains upright at a depth of 140 feet (43 meters), lying in Canadian waters and serving as a notable site for wreck divers. The SS Monrovia’s history highlights her as a significant wartime cargo ship and a vessel that served through multiple national and commercial roles before her sinking.
