English: Confederate troops marching south on N Market Street, Frederick, Maryland, during the Civil War. Photograph available from the Historical Society of Frederick County, Maryland; Catalog No. P0241.N Note: Original theory states that photo is from Sept. 10, 1862, and shows Jackson's Confederate troops marching west on Patrick Street approaching the town square at Market Street ; the soldiers are on their way to the Battle of Antietam . A revisionist theory claims that this is John Echol’s division waiting in a temporary traffic jam, to march south down S. Market street on the morning of July 9, 1864 when Jubal Early headed south .
