Preparations were at once made to relieve General Humphreys's corps, to report to General Sheridan; but the condition of the roads prevented immediate movement. On the morning of the 31st, General Warren reported favorably to getting possession of the White Oak Road, and was directed to do so. To accomplish this, he moved with one division, instead of his whole corps, which was attacked by the enemy in superior force and driven back on the 2d division before it had time to form, and it, in turn, forced back upon the 3d division, when the enemy was checked. A division of the 2d corps was immediately sent to his support, the enemy driven back with heavy loss, and possession of the White Oak Road gained. Sheridan advanced, and with a portion of his cavalry got possession of the Five Forks; but the enemy, after the affair with the 5th corps, reinforced the rebel cavalry, defending that point with infantry, and forced him back towards Dinwiddie Court House. Here General Sheridan displayed great generalship. Instead of retreating with his whole command on the main army, to tell the story of superior forces encountered, he deployed his cavalry on foot, leaving only mounted men enough to take charge of the horses. This compelled the enemy to deploy over a vast extent of wooded and broken country, and made his progress slow. At this juncture he dispatched to me what had taken place, and that he was dropping back slowly on Dinwiddie Court House. General Mackenzie's cavalry and one division of the 5th corps were immediately ordered to his assistance. Soon after receiving a report from General Meade that Humphreys could hold our position on the Boydton Road, and that the other two divisions of the 5th corps could go to Sheridan, they were so ordered at once. Thus the operations of the day necessitated the sending of Warren, because of his accessibility, instead of Humphreys, as was intended, and precipitated intended movements. On the morning of the 1st of April, General Sheridan, reinforced by General Warren, drove the enemy back on Five Forks, where, late in the evening, he assaulted and carried his strongly fortified position, capturing all his artillery and between five and six thousand prisoners.
About the close of this battle, Brevet Major-General Charles Griffin relieved Major-General Warren in command of the 5th corps. The report of this reached me after nightfall. Some apprehensions filled my mind lest the enemy might desert his lines during the night, and by falling upon General Sheridan before assistance could reach him, drive him from his position and open the way for retreat. To guard against this, General Miles's division of Humphreys's corps was sent to reinforce him, and a bombardment was commenced and kept up until four o'clock in the morning (April 2), when an assault was ordered on the enemy's lines. General Wright penetrated the lines with his whole corps, sweeping everything before him, and to his left towards Hatcher's Run, capturing many guns and several thousand prisoners. He was closely followed by two divisions of General Ord's command, until he met the other division of General Ord's that had succeeded in forcing the enemy's lines near Hatcher's Run.
Generals Wright and Ord immediately swung to the right, and closed all of the enemy on that side of them in Petersburg, while General Humphreys pushed forward with two divisions and joined General Wright on the left. General Parke succeeded in carrying the enemy's main line, capturing guns and prisoners, but was unable to carry his inner line. General Sheridan being advised of the condition of affairs, returned General Miles to his proper command. On reaching the enemy's lines immediately surrounding Petersburg, a portion of General Gibbon's corps, by a most gallant charge, captured two strong inclosed works--the most salient and commanding south of Petersburg--thus materially shortening the line of investment necessary for taking in the city. The enemy south of Hatcher's Run retreated westward to Sutherland's Station, where they were overtaken by Miles's division. A severe engagement ensued, and lasted until both his right and left flanks were threatened by the approach of General Sheridan, who was moving from Ford's Station towards Petersburg, and a division sent by General Meade from the front of Petersburg, when he broke in the utmost confusion, leaving in our hands his guns and many prisoners. This force retreated by the main road along the Appomattox River. During the night of the 2d the enemy evacuated Petersburg and Richmond, and retreated towards Danville. On the morning of the 3d pursuit was commenced. General Sheridan pushed for the Danville Road, keeping near the Appomattox, followed by General Meade with the 2d and 6th corps, while General Ord moved for Burkesville, along the South Side Road; the 9th corps stretched along that road behind him. On the 4th, General Sheridan struck the Danville Road near Jetersville, where he learned that Lee was at Amelia Court House. He immediately intrenched himself and awaited the arrival of General Meade, who reached there the next day.
General Ord reached Burkesville on the evening of the 5th.
On the morning of the 5th, I addressed Major-General Sherman the following communication:
"WILSON'S STATION, April 5, 1865.
