S. WILLIAMS,
Assistant Adjutant-General.

HEADQUARTERS ARMY OF THE POTOMAC,
CHANCELLORSVILLE, VA., May 4, 1863, 11 A.M.
MAJOR-GEN. SEDGWICK.

The major-general commanding directs me to say that he does not wish you to cross the river at Banks's Ford unless you are compelled to do so. The batteries at Banks's Ford command the position. If it is practicable for you to maintain a position south side of Rappahannock, near Banks's Ford, you will do so. It is very important that we retain position at Banks's Ford. Gen. Tyler commands the reserve artillery there.

J. H. VAN ALEN,
Brigadier-General and Aide-de-Camp.

SIXTH CORPS, May 4, 1863, 11 A.M.
MAJOR-GEN. BUTTERFIELD AND GEN. HOOKER.

I hold the same position. The enemy are pressing me hard. If I can hold until night, I shall cross at Banks's Ford, under instructions from Gen. Hooker, given by Brig.-Gen. Warren.

JOHN SEDGWICK, Major-General.

SEDGWICK'S HEADQUARTERS, May 4, 1863, 11.15 A.M.
MAJOR-GEN. HOOKER.

The enemy threatens me strongly on two fronts. My position is bad for such attack. It was assumed for attack, and not for defence. It is not improbable that bridges at Banks's Ford may be sacrificed. Can you help me strongly if I am attacked?

JOHN SEDGWICK, Major-General.
