Colonel C. ROSS SMITH,

Chief of Staff, Headquarters Cavalry Corps:

Nothing new from the front. The lines are quiet and as previously reported. No horses have as yet been turned over by the Reserve Brigade since last report. General Kilpatrick's quartermaster looked through the lot to-day, but took none. Gregg has not been heard from. Cannot some order, requiring these horses to be taken, by sent to headquarters of Second and Third Divisions, or the horses be turned in to Catlett's Station, so that this brigade can get off?

Very respectfully,

W. MERRITT,

Brigadier-General of Volunteers, Commanding Division.

Other reconnaissances discovered that the enemy's cavalry to the amount of a brigade was in the vicinity of Sperryville. After these reconnaissances across the Aeastham River, the fords at Oak Shade and Starke's were picketed by the enemy.
