I reached a position on the pike in rear of the Half-Way House about noon, where I was informed that the entire command was to retire to our entrenchments. General Terry furnished the rear guard from his division. The enemy did not follow or annoy us, but on the following day established himself in our front and intrenched himself so as to cover the railroad. On the 20th a vigorous attack was made on my pickets and possession gained of the advance rifle-pits on General Ames' front, and a portion of General Terry's. General Ames attempted to recover his ground buff failed. On General Terry's front the line was re-established by Colonel Howell's brigade, after a severe and sanguinary fight. Colonel Howell conducted the attack with great skill and gallantry. Our loss on that day was 702. The enemy acknowledge to a loss of 800, including Brigadier General W. S. Walker, wounded and taken prisoner. In the several actions from the 7th to the 20th, the Tenth Corps lost an aggregate of 3,387 in killed, wounded, and missing . The missing about 800, were mostly killed or badly wounded in the battle of Drewry's Bluff.

To my division commanders and the members of my staff I am under obligations for most efficient co-operation and aid.

Very respectfully, your obedient servant,

Q. A. GILLMORE,

Major-General.
