On the 12th, General Kautz, with his cavalry, was started on a raid against the Danville Railroad, which he struck at Coalfield, Powhatan, and Chula Stations, destroying them, the railroad-track, two freight trains, and one locomotive, together with large quantities of commissary and other stores; thence, crossing to the South Side Road, struck it at Wilson’s, Wellsville, and Black’s and White’s Stations, destroying the road and station-houses; thence he proceeded to City Point, which he reached on the 18th.

On the 19th of April, and prior to the movement of General Butler, the enemy, with a land force under General Hoke and an iron-clad ram, attacked Plymouth, N. C., commanded by General H. W. Wessells, and our gunboats there, and, after severe fighting, the place was carried by assault, and the entire garrison and armament captured.  The gunboat Smithfield was sunk, and the Miami disabled.

The army sent to operate against Richmond having hermetically sealed itself up at Bermuda Hundred, the enemy was enabled to bring the most, if not all, the reinforcements brought from the south by Beauregard against the Army of the Potomac.  In addition to this reinforcement, a very considerable one, probably not less than fifteen thousand men, was obtained by calling in the scattered troops under Breckinridge from the western part of Virginia.

The position of Bermuda Hundred was as easy to defend as it was difficult to operate from against the enemy.  I determined, therefore, to bring from it all available forces, leaving enough only to secure what had been gained; and accordingly, on the 22d, I directed that they be sent forward, under command of Major-General W. F. Smith, to join the Army of the Potomac.

On the 24th of May, the 9th army corps, commanded by Major-General A. E. Burnside, was assigned to the Army of the Potomac, and from this time forward constituted a portion of Major-General Meade’s command.

Finding the enemy’s position on the North Anna stronger than either of his previous ones, I withdrew on the night of the 26th to the north bank of the North Anna, and moved via Hanover Town to turn the enemy’s position by his right.

Generals Torbert’s and Merritt’s divisions of cavalry, under Sheridan, and the 6th corps, led the advance, crossed the Pamunkey River at Hanover Town, after considerable fighting, and on the 28th the two divisions of cavalry had a severe, but successful engagement with the enemy at Hawes’s Shop.  On the 29th and 30th we advanced, with heavy skirmishing, to the Hanover Court House and Cold Harbor Road, and developed the enemy’s position north of the Chickahominy.  Late on the evening of the last day the enemy came out and attacked our left, but was repulsed with very considerable loss.  An attack was immediately ordered by General Meade, along his whole line, which resulted in driving the enemy from a part of his intrenched skirmish line.
