Brigadier-General PLEASONTON,

Commanding Cavalry:

GENERAL: By direction of the general commanding this grand division, I have the honor to report to you that the rear of my corps will leave the vicinity of Warrenton about 11.30 a. m.

I would suggest that you keep the line of the Northern Branch of the Rappahannock well scouted by your cavalry, and beg that you will give me the earliest information of the presence of the enemy on our right flank, as the line is unavoidably much extended, owing to bad roads. Any information you may receive of
