HEADQUARTERS FIFTH ARMY CORPS, August 21, 1864-9.30 a.m.

Major-General HUMPHREYS:

GENERAL: The enemy showed an infantry line of battle of Flowers', but our artillery compelled it to leave. I don't think I can be whipped if dispositions will save me, for my line extends well around, with considerable reserves. If the enemy comes between me and the plank road to attack I would like to have his rear harassed if you have any little spare force to do it with. I consider the efforts this morning as demonstration to get at a knowledge of my position. The firing has ceased for a few moment past.

Respectfully,
G. K. WARREN,

Major-General.

HEADQUARTERS ARMY OF THE POTOMAC, August 21, 1864-10 a.m.

Major-General WARREN:

Major-General Parke will move at once with Ferrero's division toward your position to carry out the orders of yesterday. Major-General Hancock's troops will move at once to carry out the same orders, having arrived in this vicinity about 8 o'clock this morning. Should the enemy endeavor to penetrate between you and the plank road and attack you Hancock's troops will be at once thrown upon him.

A. A. HUMPHREYS,

Major-General and Chief of Staff.
