The first USS Saginaw was a sidewheel sloop-of-war in the United States Navy during the American Civil War. The ship was in operation throughout the 1860s, but in 1870 wrecked on what is now known as Kure Atoll, a Pacific island. The event produced several books and one of the surviving boats from the ship is in a museum. The wreck of the USS Saginaw was found in 2003.
