HEADQUARTERS DEPARTMENT OF PENNSYLVANIA,

Col. CHARLES P. STONE,
Commanding, near Leesburg, Va.:

Chambersburg, Pa.,

June 14, 1861.

SIR:

The commanding general instructs me to inform you that as soon as he can move his force, so as to strike a blow on the enemy's left, at Harper's Ferry, and follow it up with success, he will inform you, to obtain your co-operation, if circumstances, in your judgment, will permit. He desires to be informed of your position, and whether you can most advantageously threaten the Maryland or Virginia Heights opposite Harper's Ferry. He will not necessarily rely upon your cooperation, though glad to receive it. Can you stop supplies passing from Frederick County, Maryland, into Harper's Ferry?

I am, sir, very respectfully, your obedient servant,

F. J. PORTER,
Assistant Adjutant-Gen.
