Headquarters Army of the Potomac,
October 20, 1862:11 a.m.
Maj. Gen. William B. Franklin, Hagerstown:
Colonel Campbell, at Sir John's Run, reports last night that six regiments of the enemy are at North Mountain, tearing up the railroad track, and that refugees who left Martinsburg on the night of the 18th say Jackson's force came there that afternoon, and that a large force crossed the mountain to come onto the railroad above Sir John's Run. This has been communicated to General Newton, at Hancock, and General Kelley, at Cumberland, with instructions to co-operate in the protection of the railroad, and in cutting off, if possible, some part of the enemy's force.
R. B. Marcy,
Chief of Staff.
