Cartographic

Civil War Records in the Cartographic Research Room

The Cartographic Branch holds over 8,000 maps, charts, and plans relating to the Civil War. These records cover a wide range of subjects, including battles and skirmishes, fortifications, supporting facilities such as cemeteries and hospitals, and ship plans. They include manuscripts, printed, and published materials. Many of the published maps are annotated to show troop movements or positions.

The vast majority of the maps and records are Federal in origin, and were created by or for Union forces or other US government agencies. Many of the records date to the war itself, although some items also date to the post-war era, particularly maps made to accompany official government publications and reports. The holdings also include some Confederate maps and records.

Cartographic’s holdings include numerous plans for Civil War era forts and fortifications. The majority of these can be found within the RG 77, Fortification Map File, but others can also be found within the following series: RG 77, Plans of Military Posts in the United States (Miscellaneous Fortification File). Union forts are mainly represented, although some Confederate fortifications are also included, especially if Union troops eventually occupied these defenses, or if they were originally constructed prior to the Civil War. The plans show earthworks, defensive lines, and forts. Many also show barracks buildings, support structures, artillery emplacements, redoubts, and blockhouses associated with forts. The RG 92, Post and Reservation Maps series also includes similar plans for support structures, which cover quartermaster facilities such as barracks, stables, army camps, recruitment centers, prisoner depots, refugee and contraband quarters and camps, hospitals, and supply depots. Maps showing locations of quartermaster facilities are also often included.
