Union Forts at Petersburg

Based on the Official Records, Series III, Volume 5, pages 173 - 182, the following map shows the growth of Union fortifications at Petersburg from June 1864 through April 1865. The "Narrative collated from the reports of N. Michler" lays out a fairly detailed chronological description of how fortifications came about and when. The original map is from Michler's 1866 version, scanned at 600dpi (2 inches/mile) at the National Archives in College Park, MD, July 2013. This version,  scaled by a factor of 6 to 200 pixels/mile has also been cropped to show only the relevant fortifications.
