John Singleton Mosby (December 6, 1833 – May 30, 1916), also known by his nickname, the "Gray Ghost", was a Confederate army cavalry battalion commander in the American Civil War. His command, the 43rd Battalion, 1st Virginia Cavalry, known as Mosby's Rangers or Mosby's Raiders, was a partisan ranger unit noted for its lightning quick raids and its ability to elude Union Army pursuers and disappear, blending in with local farmers and townsmen.
