SS Rio Tercero was a cargosteamship that was launched in England in 1912 as Eboe. She was renamed Fortunstella in 1938, and Rio Tercero in 1941. A U-boat sank her in the Battle of the Atlantic in 1942.
She was built for the African Steam Ship Company, which was part of Elder, Dempster & Co. Italian owners bought her in 1938. Argentina interned her in 1940, and took her over in 1941. She was in Argentinian service when she was sunk.
She was the fourth of five Elder, Dempster ships that were called Eboe. The first three were 19th-century steamships.[1] The fifth was a motor ship that was launched in 1952, and sold and renamed in 1977.[2]
Palmer's built Eboe as yard number 821. She was launched on 25 September 1912 and completed that December.[4] Her registered length was 405.1 ft (123.5 m), her beam was 54.0 ft (16.5 m), and her depth was 23.5 ft (7.2 m).[5] She had berths for 12 passengers, and carried a crew of 40.[6] Her tonnages were 4,866 GRT and 2,965 NRT.[5]
Eboe had a single screw, driven by a three-cylinder triple-expansion engine of Palmer's own manufacture. It was rated at 566 NHP,[5] and gave her a speed of 11 knots (20 km/h).[4]
On 30 November 1938 Fratelli Rituzzo ("Rituzzo Brothers") bought Eboe and her sister ship Ebani for £12,000 each.[6] They were registered in Naples and renamed Fortunstella and Maristella respectively.[9]Fortunstella's Italian call sign was IBHM.[10]
In June 1940 Italy declared war on France and the UK. Both Fortunstella and Maristella took refuge in Argentina. Fortunstella was in port at Necochea. On 25 August 1941[11] the government of Argentina bought 16 Italian merchant ships, including both Fortunstella and Maristella,[12] which it renamed Rio Tercero and Rio Atuel respectively. They were managed by the Flota Mercante del Estado ("State Merchant Fleet");[6] and registered in Buenos Aires. Rio Tercero's call sign was LOII.[13]
U-202's commander, Kapitänleutnant Hans-Heinz Linder, claimed that the ship displayed no neutrality markings, and he did not know she was Argentinian until he questioned the survivors afterward.[11] US aircraft attacked U-202, forcing her to dive. The submarine chaser USS SC-503 rescued survivors.[14]
