The Maryland Campaign Part 3: The Battle of Antietam

October 25-27, 2019

A BGES Civil War Field University Program

The Battle Fog at Antietam
From The Photographic History of the Civil War

After South Mountain, Lee had determined the division under Major General Lafayette McLaws was seriously threatened, and that the approach of McClellan’s army necessitated his withdrawal from Maryland. Lee gave orders accordingly. In response, Jackson pleaded with a little more time to secure the surrender of the large garrison in Harpers Ferry. Lee agreed to the delay and hunkered down behind the Antietam Creek, a tributary of the Potomac River which was at his back. Lee expected to be attacked, but McClellan delayed more than a day, allowing the majority of Jackson’s command to come into line with others en route. A.P. Hill was left in Harpers Ferry to consolidate and process the surrender of the U.S. troops–he would be up late on the day of the 17th. This is the story of America’s bloodiest single day. The extensive walking tour is conducted by the two men who know this battlefield better than anyone else. A special program you won’t want to miss.
