unfortunately, on the following day, Colonel L. O. Morris, Seventh New York,* killed in the trenches by a sharpshooter. When it is remembered that I had only my two smallest divisions actually engaged, it will be seen that loss in commanders was unusually severe. It was a blow to the corps from which it did not soon recover.

Soon after the failure of the assault, I was ordered to send Birney's division to support General Warren, where it remained until the 5th. We occupied this position until the 11th, there being no material change except the extending of my line to the left as far as the Chickahominy. Siege operations were conducted for several days, our lines being advanced by regular approaches, and a mine commenced. Before any practical result was reached the siege operations were abandoned. The daily skirmishing was sharp and caused us some loss. The nights were characterized by heavy artillery firing and sometimes heavy musketry, the close proximity of our lines causing unusual nervousness. On the 12th, a new and shorter line, covering Cold Harbor, was built, and roads opened to the rear of the old line, and immediately after dark the troops, except the pickets, were drawn out of the first line and assembled in the second, from which they moved about 11 p. m. to Long Bridge. The picket-line was drawn in at 3 a. m. on the 13th without molestation. This terminated the operations of my command during he fourth epoch of the campaign.

The bearing of the troops under my command on the march and during the operations on the Totopotomoy, and especially at the bloody battle of Cold Harbor, was distinguished for bravery and good conduct. My subordinate commanders deserve high commendation for their faithful performance of duty. My staff behaved with their usual zeal and gallantry. Captain Alexander M. McCune, acting assistant provost-marshal, Second Corps, a valuable officer, was mortally wounded on the evening of the 5th by a shot thrown from the enemy's batteries.
