Join us as Benjamin L. Cwayna presents â âSlaughter along a Stone Wall: Greggâs South Carolina Brigade during the Maryland Campaign.âAs Leeâs victorious army pivoted away from the bloody field at Manassas and crossed over the Potomac, a simmering feud between Stonewall Jackson and his staff on one side and A.P. Hill and his South Carolina Brigade on the other, took center stage. Multiple arrests, accusations, innuendo, and other high drama played out as the army approached its most critical fight of the war along the banks of the Antietam. With so much on the line that Fall, egos and critical decisions both on and off the field would help define a campaign and set in motion a series of events that saved Leeâs army in an obscure 40-acre cornfield.
