When I rejoined the Army of the Potomac, near Chesterfield Station, the heavy battles around Spottsylvania had been fought, and the complicated manoeuvres by which the whole Union force was swung across the North Anna were in process of execution. In conjunction with these manoeuvres Wilson's division was sent to the right flank of the army, where he made a reconnoissance south of the North Anna as far as Little River, crossing the former stream near Jericho Mills. Wilson was to operate from day to day on that flank as it swung to the south, covering to New Castle ferry each advance of the infantry and the fords left behind on the march. From the 26th to the 30th these duties kept Wilson constantly occupied, and also necessitated a considerable dispersion of his force, but by the 31st he was enabled to get all his division together again, and crossing to the south side of the Pamunkey at New Castle ferry, he advanced toward Hanover Court House. Near Dr Pride's house he encountered a division of the enemy's cavalry under General W. H. F. Lee, and drove it back across Mechamp's Creek, thus opening communication with the right of our infantry resting near Phillips's Mills. Just as this had been done, a little before dark, Wilson received an order from General Meade directing him to push on toward Richmond until he encountered the Confederates in such strength that he could no longer successfully contend against them, and in compliance with this order occupied Hanover Court House that same day. Resuming his march at daylight on June 1, he went ahead on the Ashland road while sending Chapman's brigade up the south bank of the South Anna to destroy the bridges on that stream. Chapman having succeeded in this work, Wilson re-united his whole command and endeavored to hold Ashland, but finding the Confederate cavalry and infantry there in strong force, he was obliged to withdraw to Dr. Price's house. Here he learned that the army had gone to the left toward Cold Harbor, so on the 2d of June he moved to Hawe's Shop.
While Wilson was operating thus on the right, I had to cover with Gregg's and Torbert's divisions the crossing of the army over the Pamunkey River at and near Hanovertown. Torbert having recovered from the illness which overtook him in the Wilderness, had now returned to duty. The march to turn the enemy's right began on the 26th. Torbert and Gregg in advance, to secure the crossings of the Pamunkey and demonstrate in such manner as to deceive the enemy as much as possible in the movement, the two cavalry divisions being supported by General D. A. Russell's division of the Sixth Corps.
To attain this end in the presence of an ever-watchful foe who had just recently been reinforced in considerable numbers from Richmond and further south—almost enough to make up the losses he had sustained in the Wilderness and at Spottsylvania—required the most vigorous and zealous work on the part of those to whom had been allotted the task of carrying out the initial manoeuvres. Torbert started for Taylor's ford on the Pamunkey with directions to demonstrate heavily at that point till after dark, as if the crossing was to be made there, and having thus impressed the enemy, he was to leave a small guard, withdraw quietly, and march to Hanovertown ford, where the real crossing was to be effected. Meanwhile Gregg marched to Littlepage's crossing of the Pamunkey, with instructions to make feints in the same manner as Torbert until after dark, when he was to retire discreetly, leaving a small force to keep up the demonstration, and then march rapidly to Hanovertown crossing, taking with him the pontoon-bridge.
At the proper hour Russell took up the march and followed the cavalry. The troops were in motion all night, undergoing the usual delays incident to night marches, and, early on the morning of the 27th the crossing was made, Custer's brigade of Torbert's division driving from the ford about one hundred of the enemy's cavalry, and capturing between thirty and forty prisoners. The remainder of Torbert's division followed this brigade and advanced to Hanovertown, where General Gordon's brigade of Confederate cavalry was met. Torbert attacked this force with Devin's brigade, while he sent Custer to Hawe's Shop, from which point a road leading to the right was taken that brought him in rear of the enemy's cavalry; when the Confederates discovered this manoeuvre, they retired in the direction of Hanover Court House. Pursuit continued as far as a little stream called Crump's Creek, and here Torbert was halted, Gregg moving up on his line meanwhile, and Russell encamping near the crossing of the river. This completed our task of gaining a foothold south of the Pamunkey, and on the 28th the main army crossed unharassed and took up a position behind my line, extending south from the river, with the Sixth Corps on the right across the Hanover Court House road at Crump's Creek, the Second Corps on the left of the Sixth, and the Fifth Corps about two miles in front of Hanovertown, its left extending to the Tolopotomy.
There was now much uncertainty in General Grant's mind as to the enemy's whereabouts, and there were received daily the most conflicting statements as to the nature of Lee's movements. It became necessary, therefore, to find out by an actual demonstration what Lee was doing, and I was required to reconnoitre in the direction of Mechanicsville. For this purpose I moved Gregg's division out toward this town by way of Hawe's Shop, and when it had gone about three-fourths of a mile beyond the Shop the enemy's cavalry was discovered dismounted and disposed behind a temporary breastwork of rails and logs.
This was the first occasion on which, since the battle of Yellow Tavern, the Confederate troopers had confronted us in large numbers, their mounted operations, like ours, having been dependent more or less on the conditions that grew out of the movements in which Lee's infantry had been engaged since the 14th of May.
On that date General Lee had foreshadowed his intention of using his cavalry in connection with the manoeuvres of his infantry by issuing an order himself, now that Stuart was dead, directing that the "three divisions of cavalry serving with the army [Lee's] will constitute separate commands, and will report directly to and receive orders from the headquarters of the army." The order indicates that since Stuart's death the Confederate cavalry had been re-organized into three divisions, that were commanded respectively by General Wade Hampton, General Fitzhugh Lee, and General W. H. F. Lee, the additional division organization undoubtedly growing out of the fact, that General M. C. Butler's brigade of about four thousand men had joined recently from South Carolina.
When this force developed in Gregg's front, he attacked the moment his troops could be dismounted; and the contest became one of exceeding stubborness, for he found confronting him Hampton's and Fitzhugh Lee's divisions, supported by what we then supposed to be a brigade of infantry, but which, it has since been ascertained, was Butler's brigade of mounted troops; part of them armed with long-range rifles. The contest between the opposing forces was of the severest character and continued till late in the evening. The varying phases of the fight prompted me to reinforce Gregg as much as possible, so I directed Custer's brigade to report to him, sending, meanwhile, for the other two brigades of Torbert, but these were not available at the time—on account of delays which occurred in relieving them from the line at Crump's Creek—and did not get up till the fight was over. As soon as Custer joined him, Gregg vigorously assaulted the Confederate position along his whole front; and notwithstanding the long-range rifles of the South Carolinians, who were engaging in their first severe combat it appears, and fought most desperately, he penetrated their barricades at several points.
The most determined and obstinate efforts for success were now made on both sides, as the position at Hawe's Shop had become of very great importance on account of the designs of both Lee and Grant. Lee wished to hold this ground while he manoeuvred his army to the line of the Tolopotomy, where he could cover the roads to Richmond, while Grant, though first sending me out merely to discover by a strong reconnoissance the movements of the enemy, saw the value of the place to cover his new base at the White House, and also to give us possession of a direct road to Cold Harbor. Hawe's Shop remained in our possession finally, for late in the evening Custer's brigade was dismounted and formed in close column in rear of Gregg, and while it assaulted through an opening near the centre of his line, the other two brigades advanced and carried the temporary works. The enemy's dead and many of his wounded fell into our hands; also a considerable number of prisoners, from whom we learned that Longstreet's and Ewell's corps were but four miles to the rear.
The battle was a decidedly severe one, the loss on each side being heavy in proportion to the number of troops engaged. This fight took place almost immediately in front of our infantry, which, during the latter part of the contest, was busily occupied in throwing up intrenchments. Late in the afternoon I reported to General Meade the presence of the enemy's infantry, and likewise that Hampton's and Fitzhugh Lee's divisions were in my front also, and asked, at the same time; that some of our infantry, which was near at hand, be sent to my assistance. I could not convince Meade that anything but the enemy's horse was fighting us, however, and he declined to push out the foot-troops, who were much wearied by night marches. It has been ascertained since that Meade's conclusions were correct in so far as they related to the enemy's infantry; but the five cavalry brigades far outnumbered my three, and it is to be regretted that so much was risked in holding a point that commanded the roads to Cold Harbor and Meadow bridge, when there was at hand a preponderating number of Union troops which might have been put into action. However, Gregg's division and Custer's brigade were equal to the situation, all unaided as they were till dark, when Torbert and Merritt came on the ground. The contest not only gave us the crossroads, but also removed our uncertainty regarding Lee's movements, clearly demonstrating that his army was retiring by its right flank, so that it might continue to interpose between Grant and the James River; as well as cover the direct route to Richmond.
