HEADQUARTERS CAVALRY BRIGADE,
Near Falls Church, Va., July 11, 1864.

Lieutenant Colonel J. H. TAYLOR,

Assistant Adjutant-General and Chief of Staff:

COLONEL: I have nothing of importance to report. Scouting parties which have come in report all quiet outside, and small parties of rebels, supposed to be Mosby's men and stragglers, in the vicinity of Edwards Ferry. All measures possible will be taken to keep us well informed of any movements in the country, from here to the Potomac, toward Dranesville, and as far up as practicable; also in the direction of the gaps.

Very respectfully, your obedient servant,

H. M. LAZELLE,
