HEADQUARTERS SECOND ARMY CORPS, September 10, 1864-2 a. m.

General HUMPHREYS, Chief of Staff:

General Mott reports at 1.30 a. m. that he has carried the enemy's rifle-pits and is establishing his line on the crest near the plank road. It was done by the bayonet. He has a few prisoners and is reversing the line.

HEADQUARTERS SECOND CORPS, September 10, 1864. (Received 1 p. m.)

General HUMPHREYS,
Chief of Staff, Army of the Potomac:

About 3 this morning the enemy attacked the right of my new picket-line, recapturing the picket-pits to the plank road. From that point I hold and have reversed their line for about half a mile to the left of the road. I occupy the crest at the Chimneys. At this point the enemy's picket-pits are about fifteen yards from ours and I anticipate war to-night. There was some bad management in placing the right of the line last right. It was intended to fill up the enemy's pits there and make a new line along the edge of the ravine, but the regimental commander extended his line down the ravine, which subjected him to a flank attack. I believe I sent up about 90 prisoners. My own loss in killed, wounded, and prisoners is about 40, I hear, though it may be less. Lieutenant-Colonel Meikel, Twentieth Indiana, was severely, if not mortally, wounded. Picket-firing is sharp there to-day.

WINF'D S. HANCOCK,

Major-General.

(Same to General Warren.)

Since last report the whole of the Second Division has bee placed in camp near the Deserted House. The First Division is camped near the Jones and Chieves houses. Both divisions have large details still at work cutting timber in front of the rear line. The picket-line in front of the advanced works on the plank road was advanced last night to the position heretofore held by the enemy. About 80 prisoners were captured.
