This is an unusual map that shows the District of Columbia with street grids for Washington and Alexandria. Many of the forts and roads within the District are shown in color. The information shown is very detailed, including forested areas and farmsteads. This map is plate No. 1 from the report. It is an early published Civil War map; most reports and maps withheld publication until the 1890's to allow time for the national wound to heal sufficiently for a public discussion of the conflict.
