Federal Reconnaissance, Base Map dated September 13, 1864, with later annotations

Work on this map began after the Federal offensives leading to the capture of the Weldon Railroad, August 18. The base map shows Federal lines extending from the Petersburg & Norfolk Railroad to Fort Wadsworth and Globe Tavern. Confederate lines are shown in red (and pencil), Federal lines in blue. This appears to be an attempt to fill in some of the terrain features between the lines from Jerusalem Plank Road west. Some Union troop positions are tentatively sketched in, which may be more clearly seen in the detail following.
