Camp at Hartwood, Va., November 21, 1862.
The center grand division will march to-morrow morning in the direction of the crossing of Potomac Creek by the Aquia Railroad, and encamp near that point. The march will be at the times named, and over the following routes:
Butterfield's corps will commence the movement at 7 o'clock, and over the route lying to the left of the Falmouth road.
The First Division of Stoneman's corps will move at 8 o'clock, by the Falmouth road. The Second Division, by the same route, will march the day following.
If the ground is favorable, Butterfield's corps will be encamped on the west side of the railroad, and Stoneman's on the east, and both corps on the south side of Potomac Creek.
After having left a sufficient force to perform the picket duty required by instructions of this date, Averell's cavalry brigade will march by either route, as soon as cleared, and until further orders will be encamped on Potomac Creek, on the west side of the railroad.
Headquarters to-morrow night will be in the immediate vicinity of the camp.
