On the 19th, General Sheridan, on his return from his expedition against the Virginia Central Railroad, arrived at the White House just as the enemy's cavalry was about to attack it, and compelled it to retire. The result of this expedition was, that General Sheridan met the enemy's cavalry near Trevilian Station, on the morning of the 11th of June, whom he attacked, and after an obstinate contest drove from the field in complete rout. He left his dead and nearly all his wounded in our hands, and about four hundred prisoners and several hundred horses. On the 12th he destroyed the railroad from Trevilian Station to Louisa Court House. This occupied until three o'clock P.M., when he advanced in the direction of Gordonsville. He found the enemy reinforced by infantry, behind well-constructed rifle-pits, about five miles from the latter place and too strong to successfully assault. On the extreme right, however, his reserve brigade carried the enemy's works twice, and was twice driven therefrom by infantry. Night closed the contest. Not having sufficient ammunition to continue the engagement, and his animals being without forage (the country furnishing but inferior grazing), and hearing nothing from General Hunter, he withdrew his command to the north side of the North Anna, and commenced his return march, reaching White House at the time before stated. After breaking up the depot at that place, he moved to the James River, which he reached safely after heavy fighting. He commenced crossing on the 25th, near Fort Powhatan, without further molestation, and rejoined the Army of the Potomac.
On the 22d, General Wilson, with his own division of cavalry of the Army of the Potomac, and General Kautz's division of cavalry of the Army of the James moved against the enemy's railroads south of Richmond. Striking the Weldon Railroad at Reams's Station, destroying the depot and several miles of the road, and the South Side road about fifteen miles from Petersburg, to near Nottoway Station, where he met and defeated a force of the enemy's cavalry. He reached Burkesville Station on the afternoon of the 23d, and from there destroyed the Danville Railroad to Roanoke Bridge, a distance of twenty-five miles, where he found the enemy in force, and in a position from which he could not dislodge him. He then commenced his return march, and on the 28th met the enemy's cavalry in force at the Weldon Railroad crossing of Stony Creek, where he had a severe but not decisive engagement. Thence he made a detour from his left with a view of reaching Reams's Station (supposing it to be in our possession). At this place he was met by the enemy's cavalry, supported by infantry, and forced to retire, with the loss of his artillery and trains. In this last encounter, General Kautz, with a part of his command, became separated, and made his way into our lines. General Wilson, with the remainder of his force, succeeded in crossing the Nottoway River and coming in safely on our left and rear. The damage to the enemy in this expedition more than compensated for the losses we sustained. It severed all connection by railroad with Richmond for several weeks.
With a view of cutting the enemy's railroad from near Richmond to the Anna rivers, and making him wary of the situation of his army in the Shenandoah, and, in the event of failure in this, to take advantage of his necessary withdrawal of troops from Petersburg, to explode a mine that had been prepared in front of the 9th corps and assault the enemy's lines at that place, on the night of the 26th of July the 2d corps and two divisions of the cavalry corps and Kautz's cavalry were crossed to the north bank of the James River and joined the force General Butler had there. On the 27th the enemy was driven from his intrenched position, with the loss of four pieces of artillery. On the 28th our lines were extended from Deep Bottom to New Market Road, but in getting this position were attacked by the enemy in heavy force. The fighting lasted for several hours, resulting in considerable loss to both sides. The first object of this move having failed, by reason of the very large force thrown there by the enemy, I determined to take advantage of the diversion made, by assaulting Petersburg before he could get his force back there. One division of the 2d corps was withdrawn on the night of the 28th, and moved during the night to the rear of the 18th corps, to relieve that corps in the line, that it might be foot-loose in the assault to be made. The other two divisions of the 2d corps and Sheridan's cavalry were crossed over on the night of the 29th and moved in front of Petersburg. On the morning of the 30th, between four and five o'clock, the mine was sprung, blowing up a battery and most of a regiment, and the advance of the assaulting column, formed of the 9th corps, immediately took possession of the crater made by the explosion, and the line for some distance to the right and left of it, and a detached line in front of it, but for some cause failed to advance promptly to the ridge beyond. Had they done this, I have every reason to believe that Petersburg would have fallen. Other troops were immediately pushed forward, but the time consumed in getting them up enabled the enemy to rally from his surprise (which had been complete), and get forces to this point for its defence. The captured line thus held being untenable, and of no advantage to us, the troops were withdrawn, but not without heavy loss. Thus terminated in disaster what promised to be the most successful assault of the campaign.
