John Singleton Mosby (1833-1916) was born in Powhatan County, Virginia. Having already established a thriving legal practice and with a wife and children, Mosby joined Confederate forces with the outbreak of the Civil War in Virginia. Eventually coming under the command of famous cavalry commander J.E.B. Stuart. Noted for his ability as a cavalry raider and scout, Mosby was given permission to form a cavalry partisan unit in late 1862. His "43rd Battalion, Virginia Cavalry," proved a significant hindrance to Federal operations in the northern Shenandoah Valley and Northern Virginia, raiding and ambushing supply lines. He surrendered his command on June 17, 1865, months after Lee's surrender at Appomattox. Following the war however, Mosby engaged in reconciliatory politics. He resumed his law practice, but also served in several local and federal positions, including Consul to Hong Kong.
