CAPTAIN: I have the honor to report that I left this place at noon yesterday and proceeded to Waterford, Va. Found the rebels had left Waterford about one hour and a half before I arrived. I then proceeded to Wheatland, struck the grade, and from thence to Morrisonville, and from Morrisonville I went to Hillsborough, scouting the woods and mountain on the route. I joined te force sent from Harper's Ferry at Hillsborough about 4 p. m.; both commands then proceeded to Wheatland, Morrisonville, and Lovettsville. Near the Short Hill Mountain, and near Morrisonville, I captured 4 of Mosby's guerrillas, who were in the act of carrying off grain. Turned back several wagons loaded with grain. Mosby, with about 150 men, was at Upperville yesterday. The rebels are numerous in Loundoun, mostly in small squads. I took them by surprise yesterday.

I have the honor to be, respectfully, your obedient servant,

DANIEL M. KEYES,

Captain Independent Loudoun (Virginia) Rangers.
