C. S. A.
Maj. Gen. Lafayette McLaws' Command
(September 12-13, 1862)
McLaws' Command consisted of Kershaw's, Barksdale's, Semmes' and Cobb's Brigades of his own Division and R. H. Anderson's Division of six Brigades-Wilcox's, Mahone's, Featherston's, Armistead's, Wright's and Pryor's. On the morning of the 12th, Kershaw and Barksdale crossed Pleasant Valley, ascended Maryland Heights at Solomon's Gap and moving along the crest of the heights, attacked and drove the Union forces from the southern end of them and into Harpers Ferry, on the 13th. Cobb moved along the eastern base of the heights in support of Kershaw and Barksdale. Wright moved along the South Mountain and took position on its bold extremity overlooking Weaverton. Pryor, Armistead and Featherstone moved down Pleasant Valley and occupied Weaverton and Sandy Hook. These movements shut in Harpers Ferry from the Maryland side of the Potomac. Semmes' Brigade held Brownsville Pass, and Mahone's was in Pleasant Valley, prepared to assist Semmes or to re-enforce Munford's Cavalry Brigade in front of Crampton's Pass.
