“BRIGADIER-GENERAL WILSON,
“Commanding Third Division Cavalry Corps.

“The major-general commanding directs that you move your command at 2 A. M. to-morrow, the 22d instant, in execution of the duty assigned you of destroying certain railroads.  Despatches received from the White House state that Hampton’s cavalry was before that place yesterday evening, and that General Sheridan had also reached there, hence it is desirable that you should march at the earliest moment.  In passing Petersburg you will endeavor to avoid the observation of the enemy, and then move by the shortest routes to the intersection of the Petersburg and Lynchburg, and the Richmond and Danville railroads, and destroy both these roads to the greatest extent possible, continuing their destruction until driven from it by such attacks of the enemy as you can no longer resist.  The destruction of those roads to such an extent that they cannot be used by the enemy in connection with Richmond during the remainder of the campaign is an important part of the plan of campaign.  The latest information from Major-General Hunter represents him to be a few miles west of Lynchburg.  He may endeavor to form a junction with this army; you will communicate with him if practicable, and have delivered to him verbally the contents of the following copy of a communication from Lieutenant-General Grant to the major-general commanding this army.  Lieutenant Brooks, who will accompany your expedition part of the way, should be informed where General Hunter will probably be found.

“The success of your expedition will depend upon the secrecy with which it is commenced, and the celerity with which its movements are conducted; your command will, therefore, have with it the lightest supplies and smallest number of wheels consistent with the thorough execution of the duty, the supplies of the section of country you will operate in being taken into account.  Upon the completion of the work assigned you, you will rejoin this army.

“The chief quartermaster was directed yesterday to supply you with the implements and material for the destruction of railroads obtained for General Sheridan.

Mount Sinai Church, June 21, 1864—­6 P.M.

“MAJOR-GENERAL HUMPHREYS,”
“Chief-of-Staff. 
“The instructions of the major-general commanding, of this date, are
received.  I shall march in obedience thereto at 2 A. M. to-morrow. 
Before starting I would like to know if our infantry forces cover the
Weldon road.

“I propose striking the Southside road first at Sutherland Station, or some point in that vicinity, tearing up the track sufficiently to delay railroad communication ten or twelve hours.  At this place I shall detach a force to strike the Richmond and Danville road, by a rapid march, at the nearest point, tearing up the track at every practicable point between there and Burkeville.
