The Baltic of Antietam. 33
day, September 14) the battle of South Mountain, or Boonsboro, fought by General Lee to protect his trains and to enable General Jackson to rejoin him.
The Federals carried the passes of South Mountain at Crampton's and Turner's Gaps, and General Lee drew up his army on the west side of Antietam creek, north and south of the village of Sharps- burg, and in easy communication with General Jackson by Boteler's ford, on the Potomac, near Shepherdstown.
As soon as the necessary arrangements for the surrender of Har- per's Ferry could be made on the I5th, General Jackson, leaving General A. P. Hill at Harper's Ferry to complete these arrange- ments, marched that afternoon for Shepherdstown with his own corps (Jones' and Lawton's Divisions) and Walker's Division, and crossed the Potomac at Boteler's ford on the morning of the i6th.
