   Gen. Jackson, with Ewell's and Jackson's Divisions, left Harpers Ferry late in the afternoon of September 15th, reached Sharpsburg on the morning of the 16th, and, in the afternoon, took position on the left of Longstreet's Command; Jackson's Division formed on the right of the line, which extended from a point on the Hagerstown Pike 250 yards north of the Dunkard Church westerly through the open fields and the West Woods in the direction of Alfred Poffenberger's. Early's and Hays' Brigades of Ewell's Division were in the left rear of Jackson's Division and Lawton's and Trimble's Brigades in the woods west and northwest of the Dunkard Church. At about 10 P.M.
