USS Siboney (ID-2999)

USS Siboney (ID-2999) was a United States Navy troopship in World War I. She was the sister ship of USS Orizaba (ID-1536). Launched as SS Oriente, she was soon renamed after Siboney, Cuba, a landing site of United States forces during the Spanish–American War. After her navy service ended, she was SS Siboney for the New York & Cuba Mail Steamship Co. (commonly called the Ward Line). The ship was operated under charter by American Export Lines beginning in late 1940. During World War II she served the US Army as transport USAT Siboney and as the hospital ship USAHS Charles A. Stafford.

As a transport during World War I, Siboney made 17 transatlantic voyages for the navy carrying troops to and from Europe, and had the shortest average in-port turnaround time of all navy transports. During her maiden voyage, her steering gear malfunctioned which resulted in a collision between two other troopships in the convoy.

After her World War I service ended, Siboney was returned to the Ward Line and placed in New York–Cuba–Spain transatlantic service; the liner ran aground at Vigo, Spain, in September 1920. Despite considerable damage, she was repaired and placed back in service. In late 1921, Siboney was switched to New York–Cuba–Mexico routes, which were a popular and inexpensive way for Americans to escape Prohibition. In late 1940, she was chartered to American Export Lines to return Americans fleeing Europe at the outset of World War II, making seven roundtrips from Jersey City, New Jersey, to Lisbon.

During World War II, Siboney was requisitioned by the War Shipping Administration (WSA) and assigned to the War Department as a US Army transport. She made several transatlantic trips and called at ports in Africa, the Middle East, Canada, the Caribbean, and the United Kingdom. During a 1944 overhaul, the ship was selected for conversion to a hospital ship. Renamed USAHS Charles A. Stafford after a US Army doctor killed in action in Australia, the ship served in both the European and the Pacific Theatres. After the end of her army service, the ship was laid up in the National Defense Reserve Fleet in February 1948, and sold for scrapping in 1957.
