There are a number of both printed and manuscript maps in the Special Collections Research Center (SCRC) that concern the Civil War period. They are listed in our Map Collection finding aid online. Where known, date and cartographer are indicated. There is also a subject section in the map drawers for the Civil War. Because of their size and fragility these maps cannot be photocopied.
Also in the SCRC is the photographic version of the Gilmer maps done by Confederate engineers which duplicates originals held by the Virginia Museum of History and Culture. These maps are invaluable not only for Civil War research but also because they are the most detailed maps ever done of many areas of Virginia in the mid-nineteenth century. Many of them even include residences. These maps are available online at the Library of Congress along with other Civil War era maps.
