# Special Order 191

Special Order 191 (series 1862), also known as the "Lost Dispatch" and the "Lost Order", was a general movement order issued by Confederate Army General Robert E. Lee on about September 9, 1862, during the Maryland Campaign of the American Civil War. A lost copy of this order was recovered on September 13 by Union Army troops in Frederick County, Maryland, and read by General George B. McClellan, who changed the direction of his movement to conform to Lee's movements the document described.

## History
### Drafting

The order was drafted on or about September 9, 1862, during the Maryland Campaign. It gave details of the movements of the Army of Northern Virginia during the early days of its invasion of Maryland. Lee divided his army, which he planned to regroup later; according to the precise text Major General Stonewall Jackson was to move his command to Martinsburg while McLaws's command and Walker's command "endeavored to capture Harpers Ferry." Major General James Longstreet was to move his command northward to Boonsborough. Major General D. H. Hill's division was to act as rear guard on the march from Frederick.
Lee delineated the routes and roads to be taken and the timing for the investment of Harpers Ferry. On September 12th, from Hagerstown, Lee send the original order of the 9th to President Davis. AAG Robert Chilton signed this document Lee's staff officers, with the exception of Charles Venable, denied being involved in the promulgation of the Order. After the war D.H. Hill produced a copy of the Order written in the hand of his brother-in-law, Stonewall Jackson. No other division commander produced a copy of the Order. Longstreet claimed, in 1895, that he ate his copy.

### Union discovery of lost copy

About noon on September 13, Corporal Barton W. Mitchell of the 27th Indiana Volunteers, part of the Union XII Corps, discovered cigars wrapped in a piece of paper lying in the grass at a campground. Mitchell realized the significance of the document and turned it in to Sergeant John M. Bloss. They went to their regimental commander Colonel Silas Colgrove, who carried it to the corps headquarters. There, an aide named Samuel Pitman claimed he recognized the signature on the document as that of Robert Chilton, Confederate AAG. The 12th Corps commander, Alpheus S. Williams, sent the document to McClellan who read it.
McClellan was overcome with glee at learning planned Confederate troop movements and reportedly exclaimed, "Now I know what to do!" He confided to Brigadier General John Gibbon, "Here is a paper with which, if I cannot whip Bobby Lee, I will be willing to go home."

### Effect

In a letter written to D.H. Hill, in 1868, Lee stated that he learned McClellan had read the Order from Stuart the night of September 13th, Stuart reporting that a "Citizen of Maryland" had arrived at Boonsboro with the news. Two Northern newspapers reported no later than September 15 that Union officers had Lee's orders. Indeed, on the morning of September 15, 1862, the New York Herald, the North’s biggest newspaper, printed the following bulletin on the right-hand column on its front page:
   WASHINGTON, Sept. 14, 1862
   Officers who left Frederick this morning report that a general order of General Lee was found there, directing that two columns of the rebel army should proceed by way of Middletown, one of them destined for Greencastle, Pa., with all possible expedition, and the other to proceed by way of Williamsport or Shepherdstown, at discretion, to engage the Union forces at Harper's Ferrry. [sic]
The reasons this was both printed and overlooked are explored here.
McClellan stopped Lee's invasion at the subsequent Battle of Antietam, but many military historians believe he failed to fully exploit the strategic advantage of the intelligence because he was concerned about a possible trap (Major General Henry W. Halleck had been concerned that "Lee might draw McClellan and the army away from Washington, then turn and attack the city") or gross overestimation of the strength of Lee's army.

### Legacy

Where the lost order was discovered is not exactly known, but its general location is where today a quarry exists on the outskirts of Frederick, Maryland, A historical marker on the Monocacy National Battlefield commemorates the finding of Special Order 191 during the Maryland Campaign.
Corporal Mitchell, who found the orders, was subsequently wounded in the leg at Antietam and was discharged in 1864 due to the resulting chronic infection. He died in 1868 at the age of 52.
