A courier lost a copy of special order 191 wrapped around three cigars. Corporal Barton W. Mitchell of the 27th Indiana Volunteers found it and it ended up in General McClellan's hands. This lead to the Battle of Antietem and that battle lead to Lincoln issuing Emancipation Proclamation which kept England and France from recognizing the Confederacy as a nation.
