SPECIAL FIELD ORDERS,
HDQRS. 13TH ARMY CORPS,
DEPARTMENT OF THE TENNESSEE,
La Grange, Tenn., November 27, 1862.
Upon the forming of a junction between the forces now moving from here under Generals McPherson and Hamilton with those from Memphis under Major-General Sherman, the army in the field will be known and designated as follows:
Right wing, Major General W. T. Sherman commanding, and will be composed of the troops now under his command and such as are transferred to it by Special Orders, Numbers 30.
Center, commanded by Major General J. B. McPherson, and left wing, Brigadier General C. S. Hamilton commanding.
By order of Major General U. S. Grant:
JNO. A. RAWLINS,

HEADQUARTERS ARMY IN THE FIELD,
Old Lamar, November 28, 1862.
Brigadier General C. S. HAMILTON,
Commanding Left Wing:
GENERAL: Move to-morrow at the earliest possible hour and reach the nearest water to the south or southeast of Holly Springs. I have no information of water nearer than Lumpkin’s Mill, except directly east from Holly Springs. If I should not came up with you at Holly Springs to-morrow you can exercise your own judgment as to the expediency of sending McArthur’s division eastward to Chewalla Creek.
Detail four good companies of cavalry, well commanded, to remain at Holy Springs until they receive orders from me. I want to send them to communicate with Sherman.
U. S. GRANT,
P. S.-Holly Springs will be my headquarter after to-morrow until further orders.
