From the night of the 29th to the morning of the 31st the rain fell in such torrents as to make it impossible to move a wheeled vehicle, except as corduroy roads were laid in front of them. During the 30th, Sheridan advanced from Dinwiddie Court House towards Five Forks, where he found the enemy in full force. General Warren advanced and extended his line across the Boydton Plank Road to near the White Oak Road, with a view of getting across the latter; but, finding the enemy strong in his front and extending beyond his left, was directed to hold on where he was, and fortify. General Humphreys drove the enemy from his front into his main line on the Hatcher, near Burgess's Mills. Generals Ord, Wright, and Parke made examinations in their fronts to determine the feasibility of an assault on the enemy's lines. The two latter reported favorably. The enemy confronting us as he did, at every point from Richmond to our extreme left, I conceived his lines must be weakly held, and could be penetrated if my estimate of his forces was correct. I determined, therefore, to extend our line no farther, but to reinforce General Sheridan with a corps of infantry, and thus enable him to cut loose and turn the enemy's right flank, and with the other corps assault the enemy's lines. The result of the offensive effort of the enemy the week before, when he assaulted Fort Stedman, particularly favored this. The enemy's intrenched picket-line captured by us at that time threw the lines occupied by the belligerents so close together at some points that it was but a moment's run from one to the other. 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.

"GENERAL: All indications now are that Lee will attempt to reach Danville with the remnant of his force. Sheridan, who was up with him last night, reports all that is left, horse, foot, and dragoons, at twenty thousand, much demoralized. We hope to reduce this number one-half. I shall push on to Burkesville, and if a stand is made at Danville, will in a very few days go there. If you can possibly do so, push on from where you are, and let us see if we cannot finish the job with Lee's and Johnston's armies. Whether it will be better for you to strike for Greensboro', or nearer to Danville, you will be better able to judge when you receive this. Rebel armies now are the only strategic points to strike at.

On the morning of the 6th, it was found that General Lee was moving west of Jetersville, towards Danville. General Sheridan moved with his cavalry (the 5th corps having been returned to General Meade on his reaching Jetersville) to strike his flank, followed by the 6th corps, while the 2d and 5th corps pressed hard after, forcing him to abandon several hundred wagons and several pieces of artillery. General Ord advanced from Burkesville towards Farmville, sending two regiments of infantry and a squadron of cavalry, under Brevet Brigadier-General Theodore Read, to reach and destroy the bridges. This advance met the head of Lee's column near Farmville, which it heroically attacked and detained until General Read was killed and his small force overpowered. This caused a delay in the enemy's movements, and enabled General Ord to get well up with the remainder of his force, on meeting which, the enemy immediately intrenched himself. In the afternoon, General Sheridan struck the enemy south of Sailors' Creek, captured sixteen pieces of artillery and about four hundred wagons, and detained him until the 6th corps got up, when a general attack of infantry and cavalry was made, which resulted in the capture of six or seven thousand prisoners, among whom were many general officers. The movements of the 2d corps and General Ord's command contributed greatly to the day's success.

On the morning of the 7th the pursuit was renewed, the cavalry, except one division, and the 5th corps moving by Prince Edward's Court House; the 6th corps, General Ord's command, and one division of cavalry, on Farmville; and the 2d corps by the High Bridge Road. It was soon found that the enemy had crossed to the north side of the Appomattox; but so close was the pursuit, that the 2d corps got possession of the common bridge at High Bridge before the enemy could destroy it, and immediately crossed over. The 6th corps and a division of cavalry crossed at Farmville to its support.

Feeling now that General Lee's chance of escape was utterly hopeless, I addressed him the following communication from Farmville:

"April 7, 1865.

"GENERAL—The result of the last week must convince you of the hopelessness of further resistance on the part of the Army of Northern Virginia in this struggle. I feel that it is so, and regard it as my duty to shift from myself the responsibility of any further effusion of blood, by asking of you the surrender of that portion of the Confederate States army known as the Army of Northern Virginia.
