The USS Mercy (ID-1305/AH-4) was a notable U.S. Navy hospital ship that served during World War I, with a rich history prior to her naval service. Originally launched in March 1907 by William Cramp & Sons in Philadelphia, she was initially known as SS Saratoga, a fast steamer for the Ward Line operating on the New York to Havana route. During her commercial career, she was considered one of the fastest ships in coastal trade and was involved in several notable incidents, including a collision with a schooner in 1907 and legal controversies involving her captains. Constructed as a passenger liner, Saratoga measured approximately 420 feet in length, with a beam of around 52 feet, and was powered by steam turbines, enabling her to reach speeds of about 16 knots. She carried notable passengers, including political figures such as Cipriano Castro and Mario García Menocal, and a high-ranking clergyman, Archbishop Farley. In 1917, she was requisitioned by the U.S. government and converted into an Army transport ship, designated USAT Saratoga. She participated in the first American troop convoy to France during World War I, sailing from Hoboken to Brest, and was involved in a submarine attack near the Azores. An accidental collision with the Panama Steamship Company vessel in July 1917 caused significant damage, leading to her evacuation and subsequent rescue of all aboard. Purchased by the Navy in October 1917, she was converted into a hospital ship, commissioning as USS Mercy in January 1918. She was equipped with modern medical facilities, including operating rooms and X-ray laboratories, and was among the first Navy hospital ships to carry female nurses. Operating primarily in the Atlantic, Mercy made four transatlantic trips to France, returning nearly 2,000 wounded soldiers. Post-war, she served off the east coast, primarily based in Philadelphia, until 1934. She was later loaned to the Federal Emergency Relief Administration to serve as a home for the homeless. Decommissioned in 1934, she was struck from the Naval Vessel Register in 1938 and scrapped the following year. Her service history underscores her significance in medical support during wartime and her role in early 20th-century maritime transportation.
