Maj. Gen. William B. Franklin, Hagerstown:
Colonel Campbell, at Sir Johnís 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 Jacksonís force came there that afternoon, and that a large force crossed the mountain to come onto the railroad above Sir Johnís 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 enemyís force.
