HEADQUARTERS ARMY OF VIRGINIA, Washington, D. C., July 19, 1862.

General KING,
Fredericksburg:

Your movement of cavalry upon Beaver Dam should not be delayed a moment or it may be took late. I hope you made it last night. A rapid march in the night will certainly effect the purpose before day-light. Have you a cipher telegraph operator?

JNO. POPE,

Major-General, Commanding.

JNO. POPE,

Major-General, Commanding.
