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.

"HEADQUARTERS CAVALRY FORCES,
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.

"From Sutherlands I shall move the main body of my command by the
Great road (breaking the railroad at every convenient point) directly
to Burkeville, which, if we succeed in capturing, will afford us the
opportunity of prosecuting our work with great advantage. As soon as
I have made dispositions for communicating with Hunter and done all
the damage possible, I shall move with all possible rapidity for
Danville and Grenboro'.

"Circumstances must, however, is a great degree control our movements
after leaving Burkeville.

"If Sheridan will look after Hampton, I apprehend no difficulty, and
hope to be able to do the enemy great damage. The ammunition issued
to my command is very defective. The implements for destroying roads
have not yet arrived, but I learn from General Ingalls that they will
certainly be here early to-morrow.
