USS General W. C. Gorgas (ID-1365) was a cargo liner that was launched in Germany in 1902 as German: Prinz Sigismund for the Hamburg America Line. In 1917 the USA seized her and renamed her General W. C. Gorgas. In 1945 she was transferred to the Soviet Union, which renamed her Mikhail Lomonosov. She was scrapped in March 1958.
The Panama Railway Company operated the ship from 1917, and owned her by 1920. In 1919 she spent a few months in the United States Navy, repatriating troops from France to the USA. In 1926 Libby, McNeill & Libby bought her for use in the Pacific. She was a United States Army troopship from 1941 until 1945, when she was transferred to the USSR.
Between 1901 and 1903 HAPAG had seven new cargo liners built, each named after a prince of the House of Hohenzollern. Five of them were single-screw ships. Reiherstieg Schiffswerfte & Maschinenfabrik in Hamburg built Prinz Eitel Friedrich and . Flensburger Schiffbau-Gesellschaft in Flensburg built German: Prinz August Wilhelm and Prinz Joachim. German: Prinz Sigismund was unique, being the only member of the class built by AG "Neptun" in Rostock.
At the same time, Bremer Vulkan Schiffbau & Machinenfabrik in Bremen-Vegesack built and . These were about 32feet longer and broader than the other five, and were twin-screw ships. They thus form either a sub-class or a separate class.
German: Prinz Sigismund was named after Prince Sigismund of Prussia. "Neptun" built her as yard number 207, and launched her on 28 September 1902. In February 1903 she was damaged by fire, which delayed her completion until 6 July 1903. Her lengths were overall and registered. Her beam was, her depth was, and her draft was . Her tonnages were,, and 8,000 tons displacement. As built, she had capacity for 736 passengers.[1]
Her single screw was driven by a quadruple-expansion engine that was rated at 318 NHP and gave her a speed of 12kn.
HAPAG registered German: Prinz Sigismund at Hamburg. Her code letters were RMVQ. By 1910 she was equipped with wireless telegraphy. By 1913 her call sign was DSG. Her maiden voyage was from Hamburg to Brazil.
In 1901 HAPAG had taken over the Atlas Line, and re-branded it the "Atlas Service". It ran round-trip voyages from Port of New York and New Jersey to the Caribbean. By January 1908 German: Prinz Sigismund was on the Atlas service.[2]
For the season from September 1912 to January 1913 HAPAG advertised German: Prinz Sigismund and her sister ship German: Prinz Eitel Friedrich making round trips from New York to Fortune Island (now Long Cay), Montego Bay, Kingston, Colón, and Puerto Limón.[3] In 1913 German: Prinz Sigismund also made Caribbean trips in the summer.[4] In December 1913 German: Prinz Sigismund went to Haiti.[5]
When the First World War began in August 1914, Germany ordered its merchant ships to take refuge in the nearest neutral port. German: Prinz Sigismund stayed in Colón in Panama. On 3 February 1917 the US government seized German and Austro-Hungarian ships, both in US ports, and in ports overseas that it controlled. US authorities in Colón seized German: Prinz Sigismund and three other HAPAG ships.[6]
On 6 April 1917 the USA declared war on the Central Powers. The United States Shipping Board (USSB) assumed ownership of German: Prinz Sigismund and appointed the Panama Canal Railway to manage her. She was renamed after William C. Gorgas, the United States Army Medical Corps General who directed the sanitation measures to control mosquitoes, and mosquito-borne diseases, to enable the building of the Panama Canal. She was registered in New York. Her US official number was 215110 and her code letters were LHDV. Under Panama Railway management she took US troops and cargo to Europe.[1]
In 1919 General W. C. Gorgas was converted into a troopship to repatriate US troops from Europe. On 8 March she was commissioned into the US Navy, with the Naval Registry Identification Number ID-1365 and call sign GJDS.[7] She was assigned to the Cruiser and Transport Force. On 25 April 1919 she left New York for Bordeaux, France, where she loaded cargo and embarked US troops. She reached Philadelphia on 2 June 1919. On 5 June she left Philadelphia on her second voyage to Bordeaux. This time she brought troops to Newport News, Virginia, where she arrived on 4 July. In her two Navy voyages she repatriated a total of 2,063 troops. On 28 July she was decommissioned from the Navy and returned to the USSB.[1]
By 1920 the Panama Railway had bought General W. C. Gorgas from the USSB. In 1926 Libby, McNeill & Libby bought her and registered her in San Francisco. Libby already owned one of her sister ships, formerly German: Prinz Eitel Friedrich, now renamed Otsego. By 1934 her call sign was WQCZ, and this had superseded her code letters.
In November 1941, before the Attack on Pearl Harbor, the United States Department of War chartered General W. C. Gorgas and had her converted into a US Army troopship. She carried troops and supplies between Seattle and Alaska until January 1945, when she was returned to the War Shipping Administration at Seattle.[1]
In 1945 the ship was transferred to the USSR, who renamed her after the 18th-century polymath Mikhail Lomonosov. She was scrapped in the USSR in March 1958.[8]
