Lovettsville, Hillsborough, Purcellville, Leesburg, and Waterford roads, with artillery on the front and flanks. Getty's division is in reserve, one mile to the left and rear, at the intersection of the Waterford and Lovettsville roads, in a position to support Sturgis' division, at the same time to communicate easily with Waterford and Loverttsville. Would it not be well at so central a point to establish a depot for supplies that would serve at the same time for Waterford, Wheatland, and Hillsborough?

Very respectfully, your obedient servant,

O. B. WILLCOX,

Brigadier-General, Commanding Corps.
