The story of Monocacy

Maryland's ghost towns are mill villages, iron furnaces, and canal towns from the state's industrial era.

Monocacy National Battlefield is a unit of the National Park Service, the site of the Battle of Monocacy in the American Civil War fought on July 9, 1864. The battlefield straddles the Monocacy River southeast of the city of Frederick, Maryland. The battle, labeled "The Battle That Saved Washington," was one of the last the Confederates would carry out in Union territory. The two opposing leaders were General Jubal Early, fighting for the South, and General Lew Wallace, fighting for the North.
