Harry Ward Gilmor (January 24, 1838 – March 4, 1883) served as the Baltimore City Police Commissioner, head of the Baltimore City Police Department in the 1870s, but he was most noted as a daring and dashing Confederate cavalry officer during the American Civil War. Gilmor's daring raids, such as The Magnolia Station Raid through north-central Maryland in July 1864 during the third major Confederate invasion of the North gained his partisans fame as "Gilmor's Raiders".
