The beginning of an active September during the Civil War occurred when on September 6, Frederick, MD, was occupied by Maj. Gen. Stonewall Jackson, and other southern generals.
164 YEARS AGO
Maryland Campaign
On September 6, 1862, the Army of Northern Virginia’s troops reached Frederick, Maryland. Around the Best Farm (a part of Monocacy National Battlefield today), Generals Lee, Jackson, and Longstreet established their headquarters until September 9.
From here, the Confederate campaign strategy was put into motion with Special Order No. 191 being written. Jackson would be sent with Lafayette McLaws and John G. Walker to capture Harpers Ferry while James Longstreet and D.H. Hill were to continue northwest.
As General George B. McClellan's Army of the Potomac pursued, a misplaced copy of Lee's Special Order that was intended for General Hill would be found in the area’s fields by a Union soldier of the 27th Indiana on September 13. As McClellan was gathering his own intelligence, the fortune in finding this "Lost Order" further assisted his own movements.
