Jackson’s Command

Maj. Gen, Thomas J. Jackson, Commanding

(September 17, 1862.)

Jackson’s Command was in order of battle at 5:30 A. M., Jackson’s Division, commanded by J. R. Jones, in two lines, its right resting on the Hagerstwon Pike 230 yards north of this. Early’s and Hays’ Brigades of Ewell’s Division were on the left rear of Jones, and the Brigades of Lawton and Trimble were in the fields between the Hagerstown Pike and the East Woods. Jackson’s Command was assaulted in this position between the hours of 5:30 and 8:30 A. M. by the First and Twelfth Corps of the Army of the Potomac. At about 9:00 A. M., having been reenforced by McLaws’ and Walker’s Divisions of Longstreet’s Command, it repulsed an assault of Sedgwick’s Division of the Second Corps.

No. 315.
