Kléber was one of three Dupleix-class armored cruisers built for the French Navy in the first decade of the 20th century. Designed for overseas service and armed with eight 164.7-millimeter (6.5 in) guns, the ships were smaller and less powerfully armed than their predecessors. Completed in 1904, Kléber was initially assigned to the Mediterranean Squadron before she was transferred to the Atlantic Division three years later, where she often served as a flagship. The ship was reduced to reserve in 1909–1910 before she was sent to the Far East in 1911. Kléber returned to France two years later and was again placed in reserve.
SS Dorrigo was a cargo and passenger steam ship. It was built under the name of Saint Francois by the Smiths Dock Company at the South Bank in Middlesbrough on the River Tees in Northeast England for the Compagnie Navale de l'Océanie for the Pacific Island postal and general trade service, for which it sailed the waters of the Pacific from 1914 to 1921. The ship suffered minor damage during the First World War during the Bombardment of Papeete, prior to coming into the hands of the Langley Bros who placed it in the Sydney to Coffs Harbour route from 1922 to 1925. Upon the demise of the Langley Bros shipping firm in 1925 the vessel came into the service of John Burke and Co and was used for the Northern Queensland runs prior to its loss on 4 April 1926.
SS Fidelitas was an Italian World War II blockade runner. The steamer, escorted by German minesweepers, ran from Biscay through the English Channel in 1942, en route to Rotterdam. She later operated in Norwegian waters, under German flag, before being sunk by RAF aircraft off Ålesund in 1944.
Wheatland Montana was a steam cargo ship built in 1919 by Skinner & Eddy of Seattle for the United States Shipping Board as part of the wartime shipbuilding program of the Emergency Fleet Corporation (EFC) to restore the nation's Merchant Marine. The freighter spent the majority of her career in the Pacific connecting the West Coast of the United States with the Chinese and Japanese ports in the Far East. Early in 1928 the ship together with six other vessels was sold by the Shipping Board to the Tacoma Oriental Steamship Co. and subsequently renamed Seattle. After her owner declared bankruptcy early in 1937, the freighter was sold to Matson Navigation Company and renamed Lihue. She was then mainly employed to transport sugar and canned fruit from the Hawaiian Islands to the ports on the East Coast of the United States. In February 1942 she was chartered to transport general cargo and war supplies to the Middle East but was torpedoed by U-161 in the Caribbean Sea on February 23, and eventually sank three days later while in tow without loss of life.
Cockaponset was a steam cargo ship built in 1918–1919 by Pacific Coast Shipbuilding Company of Bay Point for the United States Shipping Board as part of the wartime shipbuilding program of the Emergency Fleet Corporation (EFC) to restore the nation's Merchant Marine. The vessel was largely employed on the Gulf Coast of the United States to Europe route until 1930 when she was laid up. In late 1940 the ship together with 15 other vessels was acquired by the British government to alleviate significant shortage of tonnage due to an ongoing German U-boat campaign. In May 1941 the freighter was torpedoed and sunk on her first war trip to the United Kingdom.

The vessel was chiefly employed on the Gulf to Europe routes throughout her career. In September 1942, while on a passage to British Guiana to load her cargo, she was torpedoed and sunk by German submarines operating at the time in the Caribbean.
