position would be to place a brigade west of the Court-House and on the Norfolk railroad. This about would require the construction of another corduroy road. A telegraph line should pass from your headquarters, via the Williams and Westbrook houses, to McCann's Station, and thence following the direct road to Prince George Court-House.

Very respectfully, your obedient servant,

D. McM. GREGG,

Brevet Major-General, Commanding Second Division.

HEADQUARTERS ARMY OF THE POTOMAC, December 13, 1864-5.05 p.m.

Bvt. Major General D. McM. GREGG,
Commanding Cavalry:

GENERAL: I am instructed by the major-general commanding to say that at present it will not be necessary for you to move your own headquarters or the camps of your troops, provided they do not interfere with the infantry camps, farther than may be necessary for you to picket from the Jerusalem plank road to the James River. On your right you will connect with the infantry pickets on the Jerusalem road, and the commanding general desires that you will frequently send patrols to front of your picket-line and to Reams' Station, so as to give timely notice of any movements of the enemy from that quarter. The commanding general desires that you establish your picket-line between the Jerusalem road and the James River to-morrow. It is probable the infantry picket-line will terminate in the vicinity of Gary's Church. The commanding general desires that you will confer with Major-General Warren, commanding Fifth Corps, as to the point of connection. As soon as your picket-line is established the commanding general wishes you to report its location.

I am, very respectfully, your obedient servant,

S. WILLIAMS,

Assistant Adjutant-General.
