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 o
