The front of the corps was oblique to the White Oak road; and on getting there, it was to swing round to the left till perpendicular to the road, keeping closed to the left. Ayres did his part well, and to the letter, bringing his division square up to the front of the return near the angle; but Crawford did not wheel to the left, as was intended. On the contrary, on receiving fire from Mumford's cavalry, Crawford swerved to the right and moved north from the return, thus isolating his division from Ayres; and Griffin, uncertain of the enemy's position, naturally followed Crawford.
The deflection of this division on a line of march which finally brought it out on the Ford road near C. Young's house, frustrated the purpose I had in mind when ordering the attack, and caused a gap between Ayres and Crawford, of which the enemy quickly took advantage, and succeeded in throwing a part of Ayres's division into confusion. At this juncture I sent word to General Warren to have Crawford recalled; for the direction he was following was not only a mistaken one, but, in case the assault at the return failed, he ran great risk of capture. Warren could not be found, so I then sent for Griffin—first by Colonel Newhall, and then by Colonel Sherman—to come to the aid of Ayres, who was now contending alone with that part of the enemy's infantry at the return. By this time Griffin had observed and appreciated Crawford's mistake, however, and when the staff-officers reached him, was already faced to the left; so, marching across Crawford's rear, he quickly joined Ayres, who meanwhile had rallied his troops and carried the return.
When Ayres's division went over the flank of the enemy's works, Devin's division of cavalry, which had been assaulting the front, went over in company with it; and hardly halting to reform, the intermingling infantry and dismounted cavalry swept down inside the intrenchments, pushing to and beyond Five Forks, capturing thousands of prisoners. The only stand the enemy tried to make was when he attempted to form near the Ford road. Griffin pressed him so hard there, however, that he had to give way in short order, and many of his men, with three pieces of artillery, fell into the hands of Crawford while on his circuitous march.
The right of Custer's division gained a foothold on the enemy's works simultaneously with Devin's, but on the extreme left Custer had a very severe combat with W. H. F. Lee's cavalry, as well as with Corse's and Terry's infantry. Attacking Terry and Corse with Pennington's brigade dismounted, he assailed Lee's cavalry with his other two brigades mounted, but Lee held on so obstinately that Custer gained but little ground till our troops, advancing behind the works, drove Corse and Terry out. Then Lee made no further stand except at the west side of the Gillian field, where, assisted by Corse's brigade, he endeavored to cover the retreat, but just before dark Custer, in concert with some Fifth Corps regiments under Colonel Richardson, drove ihe last of the enemy westward on the White Oak road.
Our success was unqualified; we had overthrown Pickett, taken six guns, thirteen battle-flags, and nearly six thousand prisoners. When the battle was practically over, I turned to consider my position with reference to the main Confederate army. My troops, though victorious, were isolated from the Army of the Potomac, for on the 31st of March the extreme left of that army had been thrown back nearly to the Boydton plank-road, and hence there was nothing to prevent the enemy's issuing from his trenches at the intersection of the White Oak and Claiborne roads and marching directly on my rear. I surmised that he might do this that night or early next morning. It was therefore necessary to protect myself in this critical situation, and General Warren having sorely disappointed me, both in the moving of his corps and in its management during the battle, I felt that he was not the man to rely upon under such circumstances, and deeming that it was to the best interest of the service as well as but just to myself, I relieved him, ordering him to report to General Grant.
I then put Griffin in command of the Fifth Corps, and directed him to withdraw from the pursuit as quickly as he could after following the enemy a short distance, and form in line of battle near Gravelly Run Church, at right angles with the White Oak road, with Ayres and Crawford facing toward the enemy at the junction of the White Oak and Claiborne roads, leaving Bartlett, now commanding Griffin's division, near the Ford road. Mackenzie also was left on the Ford road at the crossing of Hatcher's Run, Merritt going into camp on the Widow Gillian's plantation. As I had been obliged to keep Crook's division along Stony Creek throughout the day, it had taken no active part in the battle.
Years after the war, in 1879, a Court of Inquiry was given General Warren in relation to his conduct on the day of the battle. He assumed that the delay in not granting his request for an inquiry, which was first made at the close of the war, was due to opposition on my part. In this he was in error; I never opposed the ordering of the Court, but when it was finally decided to convene it I naturally asked to be represented by counsel, for the authorization of the Inquiry was so peculiarly phrased that it made me practically a respondent.
"NEW YORK CITY, May 3, 1880
"MAJOR-GENERAL W. S. HANCOCK, U. S. A.
"President Court of Inquiry, Governor's Island.
"Sir: Since my arrival in this city, under a subpoena to appear and testify before the Court of which you are president, I have been indirectly and unofficially informed that the Court some time ago forwarded an invitation to me (which has not been received) to appear personally or by counsel, in order to aid it in obtaining a knowledge as to the facts concerning the movements terminating in the battle of 'Five Forks,' with reference to the direct subjects of its inquiry. Any invitation of this character I should always and do consider it incumbent on me to accede to, and do everything in my power in furtherance of the specific purposes for which courts of inquiry are by law instituted.
