Preparing to leave Mercersburg, General J.E.B. Stuart and his staff discuss a detailed map taken from a Mercersburg resident. This map was invaluable and helped Stuart and his troopers to avoid the main roads where they were likely to encounter Federal cavalry, expeditiously sweep the area for horses, and target Federal buildings, ripe with supplies and currency. Behind Stuart, captured horses are crossing the stream as the 2nd South Carolina Cavalry rides out of town on their way to Chambersburg. The bridge shown here no longer exists.
