The USS Amphion (ID-1888) was originally built as the German passenger liner SS Köln in 1899 by J. C. Teckenborg A. G. in Geestemünde, Germany. It was a twin-screw vessel with a gross register tonnage of approximately 7,410 GRT and a registry net tonnage of 4,666. The ship measured about 429 feet in length overall, with a beam of roughly 54 feet, and a depth of 39 feet. Its construction featured a lighter, awning deck design, with two full decks and six holds fitted with large hatches, served by seventeen booms and ten winches. The vessel was powered by two triple-expansion engines driven by six Scotch boilers, providing it with a service speed suitable for its passenger and cargo routes. Designed primarily for the Baltimore and Galveston trade, Köln accommodated a limited number of cabin-class passengers but prioritized steerage, carrying up to 120 second-class and 1,850 third-class passengers. Its routes included Bremen to Baltimore, Galveston, Boston, Montreal, New Orleans, New York, Philadelphia, and Quebec. The vessel’s maximum draft was around 38 feet, with a cargo capacity that included six holds and extensive cargo handling gear. With the outbreak of World War I, Köln was interned in Boston in August 1914. Following the United States' entry into the war in April 1917, the ship was seized and transferred to the US Shipping Board, renamed Amphion, and operated under the U.S. Army as a chartered animal transport. It notably carried mules, horses, and general cargo to support American forces in Europe. During its service, Amphion engaged in combat with a German submarine, U-155, in October 1917, when it successfully evaded an attack after exchanging gunfire, with its gun crews earning commendations. In 1918, Amphion was attacked again by U-155 while returning to the U.S., sustaining damage but escaping after firing numerous rounds. Post-war, the vessel was commissioned into the U.S. Navy as USS Amphion (ID-1888), serving as a troop transport. Between May and September 1919, USS Amphion made three voyages to France, bringing home over 6,400 American troops. Decommissioned in September 1919, the ship was returned to the USSB for conversion back to civilian use but remained idle until 1920 due to extensive reconditioning requirements. Ultimately, the vessel was sold for scrap in January 1924. The Amphion's service history highlights its multifaceted role during wartime, from passenger and cargo transport to active combat, marking it as a vessel of maritime and military significance during the early 20th century.
