Lieut. Guthrie took possession of her as a prize and I have directed him to take her to New York. She is a clipper of 1,000 tons and has Nightingale of Boston on her stern and flies American colors." The slaves were freed and landed at Monrovia in Liberia but not before 160 of them died from African fever aboard "Saratoga". The sickness also spread to the crew. The Captain, who was called the "Prince of Slavers", and his Spanish second mate escaped "Nightingale" while she was anchored of St. Thomas. Lieutenant John J. Guthrie, who was from North Carolina, then a slave state, was suspected of freeing the two and letting them escape justice. The clipper eventually served in the American Civil War as the storeship USS "Nightingale" in the Gulf Blockading Squadron. Ultimately, she was abandoned at sea in 1893, while under a Norwegian flag. United States Navy operations against the slave trade largely ceased in 1861 with the outbreak of the American Civil War. Navy vessels were recalled from all over the world and reassigned to the Union blockade of southern ports. By the end of the Civil War, the African slave trade on the Atlantic had diminished further, though overland slave trading continued into the 1900s, primarily in North Africa and Central Africa. U.S. Navy officers who served in Africa between 1820 and 1861 received the "African Slave Patrol" campaign streamer.
