Owing to the hard service of the preceding month we had lost many horses, so the number of dismounted men was large; and my strength had also been much reduced by killed and wounded during the same period of activity. The effective mounted force of my two divisions was therefore much diminished, they mustering only about six thousand officers and men when concentrated on June 6 at New Castle ferry. Here they were provided with three days' rations, intended to last five days, and with two days' grain for the horses. The rations and forty rounds of ammunition per man were to be carried on the persons of the troopers, the grain on the pommel of the saddle, and the reserve ammunition in wagons. One medical wagon and eight ambulances were also furnished, and one wagon was authorized for each division and brigade headquarters; enough canvas-covered boats for a small pontoon-bridge were also provided.
My instructions permitting latitude in the route I should take, I decided to march along the north bank of the North Anna River, cross that stream at Carpenter's ford, strike the Virginia Central railroad at Trevillian Station, destroy it toward Louisa Court House, march past Gordonsville, strike the railroad again at Cobham's Station, and destroy it thence to Charlottesville as we proceeded west. The success of the last part of this programme would of course depend on the location of General Hunter when I should arrive in the region where it would be practicable for us to communicate with each other.
From my camp at New Castle ferry we crossed the Pamunkey, marched between Aylett's and Dunkirk on the Mattapony River, and on the 8th of June encamped at Polecat Station. The next day we resumed the march along the North Anna—our advance guard skirmishing with a few mounted men of the enemy, who proved to be irregulars—and bivouacked on Northeast Creek, near Young's Mills. This day I learned from some of these irregulars whom we made prisoners that Breckenridge's division of infantry, en route to the Shenandoah Valley by way of Gordonsville, was passing slowly up the railroad parallel to me, and that the enemy's cavalry had left its position on the south side of the Chickahominy, and was marching on the old Richmond and Gordonsville road toward Gordonsville, under command of General Wade Hampton, the information being confirmed by a scouting party sent out to cut the telegraph wires along the railroad in the night. Breckenridge had been ordered back to the valley by General Lee as soon as he heard of Hunter's victory near Staunton, but now that my expedition had been discovered, the movement of Breckenridge's troops on the railroad was being timed to correspond with the marches of my command till Hampton could get more nearly parallel with me.
On the 10th we resumed the march, passing by Twyman's store, crossing the North Anna at Carpenter's ford and encamping on the road leading along the south fork of the North Anna to Trevillian Station. During the evening and night of the 10th the boldness of the enemy's scouting parties, with which we had been coming into collision more or less every day, perceptibly increased, thus indicating the presence of a large force, and evidencing that his shorter line of march had enabled him to bring to my front a strong body of cavalry, although it started from Lee's army nearly two days later than I did from Grant's. The arrival of this body also permitted Breckenridge to pass on to Gordonsville, and from there to interpose between General Hunter and me at either Charlottesville or Waynesboro' as circumstances might determine.
On the night of the 10th General Hampton's division camped about three miles northwest of Trevillian, at a place called Green Spring Valley and Fitzhugh Lee's division not far from Louisa Court House, some six miles east of Trevillian. Learning that I was at Carpenter's ford, Hampton marched his division by way of Trevillian Station toward Clayton's store, on the road from Trevillian to Carpenter's ford, intending to attack me at Clayton's. Fitzhugh Lee's division was to join Hampton at Clayton's store from Louisa Court House; but on the morning of the 11th the two generals were separated by several miles.
At daylight of the 11th my march, to Trevillian Station was resumed on the direct road to that point, and engaging the enemy's pickets and advanced parties soon after setting out, we began to drive them in. Torbert had the lead with Merritt's and Devin's brigades, and as he pressed back the pickets he came upon the enemy posted behind a line of barricades in dense timber about three miles from Trevillian. Meanwhile Custer's brigade had been sent from where we bivouacked, by a wood road found on our left, to destroy Trevillian Station. In following this road Custer got to the rear of Hampton's division, having passed between its right flank and Fitzhugh Lee's division, which was at the time marching on the road leading from Louisa Court House to Clayton's store to unite with Hampton.
Custer, the moment he found himself in Hampton's rear, charged the led horses, wagons, and caissons found there, getting hold of a vast number of each, and also of the station itself. The stampede and havoc wrought by Custer in Hampton's rear compelled him to turn Rosser's brigade in that direction, and while it attacked Custer on one side, Fitzhugh Lee's division, which had followed Custer toward Trevillian, attacked him on the other. There then ensued a desperate struggle for the possession of the captured property, resulting finally in its being retaken by the enemy. Indeed, the great number of horses and vehicles could not be kept on the limited space within Custer's line, which now formed almost a complete circle; and while he was endeavoring to remove them to a secure place they, together with Custer's headquarters wagon and four of his caissons, fell into the hands of their original owners.
As soon as the firing told that Custer had struck the enemy's rear, I directed Torbert to press the line in front of Merritt and Devin, aided by one brigade of Gregg's division on their left, Gregg's other brigade in the meantime attacking Fitzhugh Lee on the Louisa Court House road. The effect of this was to force Hampton back, and his division was so hard pushed that a portion of it was driven pell-mell into Custer's lines, leaving there about five hundred prisoners. The rest of Hampton's men did not rally till they got some distance west of Trevillian, while, in the meantime, Gregg had driven Fitzhugh Lee toward Louisa Court House so far that many miles now intervened between the two Confederate divisions, precluding their union until about noon the next day, when Fitzhugh Lee effected the junction after a circuitous march in the night. The defeat of Hampton at the point where he had determined to resist my further advance, and his retreat westward, gave me undisturbed possession of the station; and after destroying the railroad to some extent toward Gordonsville, I went into camp.
From prisoners taken during the day, I gathered that General Hunter, instead of coming toward Charlottesville, as I had reason to expect, both from the instructions given me and the directions sent him by General Grant, was in the neighborhood of Lexington—apparently moving on Lynchburg—and that Breckenridge was at Gordonsville and Charlottesville. I also heard, from the same source, that Ewell's corps was on its way to Lynchburg, but this intelligence proved afterward to be incorrect, for these troops, commanded by General Early, did not leave Richmond till two days later.
There was no doubt as to the information about Hunter's general location, however. He was marching toward Lynchburg, away from instead of toward me, thus making the junction of our commands beyond all reasonable probability. So in view of this, I made up my mind to abandon that part of the scheme, and to return by leisurely marches, which would keep Hampton's cavalry away from Lee while Grant was crossing the James River. I was still further influenced to this course by the burden which was thrown on me in the large number of wounded—there being about five hundred cases of my own—and the five hundred prisoners that I would probably be forced to abandon, should I proceed farther. Besides, the recent battle had reduced my supply of ammunition to a very small amount—not more than enough for one more respectable engagement; and as the chances were that I would have to fight a great deal before I could reach Hunter, now that the enemy's cavalry and Breckenridge's infantry were between us, the risks of the undertaking seemed too great to warrant it.
