This is an Official Trailer for the documentary "Hidden in Plain Sight - Revealing the Concealed Harpers Ferry Cemeteries." Two cemeteries are featured. One cemetery was set aside by the United States Armory at Harpers Ferry in 1852 at the request of the citizenry, where Union soldiers were later buried. Another holds the remains of African American residents, including an African American soldier who was a private in the United States Colored Troops. Both are investigated using public records, interviews with local residents, and other clues to explain why these cemeteries were ignored in a town so rich in history.
