The chances of seriously injuring, us were more favorable to the enemy this time than ever they were afterward, for with the troops from Richmond, comprising three brigades of veterans and about five thousand irregulars on my front and right flank, with Gordon's cavalry in the rear, and Fitzhugh Lee's cavalry on my left flank, holding the Chickahominy and Meadow bridge, I was apparently hemmed in on every side, but relying on the celerity with which mounted troops could be moved, I felt perfectly confident that the seemingly perilous situation could be relieved under circumstances even worse than those then surrounding us. Therefore, instead of endeavoring to get away without a fight, I concluded that there would be little difficulty in withdrawing, even should I be beaten, and none whatever if I defeated the enemy.
In accordance with this view I accepted battle; and the complete repulse of the enemy's infantry, which assailed us from his intrenchments, and of Gordon's cavalry, which pressed Gregg on the Brook road, ended the contest in our favor. The rest of the day we remained on the battle-field undisturbed, and our time was spent in collecting the wounded, burying the dead, grazing the horses, and reading the Richmond journals, two small newsboys with commendable enterprise having come within our lines from the Confederate capital to sell their papers. They were sharp youngsters, and having come well supplied, they did a thrifty business. When their stock in trade was all disposed of they wished to return, but they were so intelligent and observant that I thought their mission involved other purposes than the mere sale of newspapers, so they were held till we crossed the Chickahominy and then turned loose.
After Merritt had crossed the Chickahominy and reached Mechanicsville, I sent him orders to push on to Gaines's Mills. Near the latter place he fell in with the enemy's cavalry again, and sending me word, about 4 o'clock in the afternoon I crossed the Chickahominy with Wilson and Gregg, but when we overtook Merritt he had already brushed the Confederates away, and my whole command went into camp between Walnut Grove and Gaines's Mills.
The main purposes of the expedition had now been executed. They were "to break up General Lee's railroad communications, destroy such depots of supplies as could be found in his rear, and to defeat General Stuart's cavalry." Many miles of the Virginia Central and of the Richmond and Fredericksburg railroads were broken up, and several of the bridges on each burnt. At Beaver Dam, Ashland, and other places, about two millions of rations had been captured and destroyed. The most important of all, however, was the defeat of Stuart. Since the beginning of the war this general had distinguished himself by his management of the Confederate mounted force. Under him the cavalry of Lee's army had been nurtured, and had acquired such prestige that it thought itself well-nigh invincible; indeed, in the early years of the war it had proved to be so. This was now dispelled by the successful march we had made in Lee's rear; and the discomfiture of Stuart at Yellow Tavern had inflicted a blow from which entire recovery was impossible.
In its effect on the Confederate cause the defeat of Stuart was most disheartening, but his death was even a greater calamity, as is evidenced by the words of a Confederate writer (Cooke), who says: "Stuart could be ill spared at this critical moment, and General Lee was plunged into the deepest melancholy at the intelligence of his death. When it reached him he retired from those around him, and remained for some time communing with his own heart and memory. When one of his staff entered and spoke of Stuart, General Lee said: 'I can scarcely think of him without weeping.'"
From the camp near Gaines's Mills I resumed the march to Haxall's Landing, the point on the James River contemplated in my instructions where I was to obtain supplies from General Butler. We got to the James on the 14th with all our wounded and a large number of prisoners, and camped between Haxall's and Shirley. The prisoners, as well as the captured guns, were turned over to General Butler's provost-marshal, and our wounded were quickly and kindly cared for by his surgeons. Ample supplies, also, in the way of forage and rations, were furnished us by General Butler, and the work of refitting for our return to the Army of the Potomac was vigorously pushed. By the 17th all was ready, and having learned by scouting parties sent in the direction of Richmond and as far as Newmarket that the enemy's cavalry was returning to Lee's army I started that evening on my return march, crossing the Chickahominy at Jones's bridge, and bivouacking on the 19th near Baltimore crossroads.
My uncertainty of what had happened to the Army of the Potomac in our absence, and as to where I should find it, made our getting back a problem somewhat difficult of solution, particularly as I knew that reinforcements for Lee had come up from the south to Richmond, and that most likely some of these troops were being held at different points on the route to intercept my column. Therefore I determined to pass the Pamunkey River at the White House, and sent to Fort Monroe for a pontoon-bridge on which to make the crossing. While waiting for the pontoons I ordered Custer to proceed with his brigade to Hanover Station, to destroy the railroad bridge over the South Anna, a little beyond that place; at the same time I sent Gregg and Wilson to Cold Harbor, to demonstrate in the direction of Richmond as far as Mechanicsville, so as to cover Custer's movements. Merritt, with the remaining brigades of his division, holding fast at Baltimore crossroads to await events.
After Gregg and Custer had gone, it was discovered that the railroad bridge over the Pamunkey, near the White House, had been destroyed but partially—the cross-ties and stringers being burned in places only—and that it was practicable to repair it sufficiently to carry us over. In view of this information General Merritt's two brigades were at once put on the duty of reconstructing the bridge. By sending mounted parties through the surrounding country, each man of which would bring in a board or a plank, Merritt soon accumulated enough lumber for the flooring, and in one day the bridge was made practicable. On the 22d Gregg, Wilson, and Custer returned. The latter had gone on his expedition as far as Hanover Station, destroyed some commissary stores there, and burned two trestle bridges over Hanover Creek. This done, he deemed it prudent to retire to Hanovertown. The next morning he again marched to Hanover Station, and there ascertained that a strong force of the enemy, consisting of infantry, cavalry, and artillery, was posted at the South Anna bridges. These troops had gone there from Richmond en route to reinforce Lee. In the face of this impediment Custer's mission could not be executed fully, so he returned to Baltimore crossroads.
The whole command was drawn in by noon of the 22d, and that day it crossed the Pamunkey by Merritt's reconstructed bridge, marching to Ayletts, on the Mattapony River, the same night. Here I learned from citizens, and from prisoners taken during the day by scouting parties sent toward Hanover Court House, that Lee had been, forced from his position near Spottsylvania Court House and compelled to retire to the line of the North Anna. I then determined to rejoin the Army of the Potomac at the earliest moment, which I did by making for Chesterfield Station, where I reported to General Meade on the 24th of May.
Our return to Chesterfield ended the first independent expedition the Cavalry Corps had undertaken since coming under my command, and our success was commended highly by Generals Grant and Meade, both realizing that our operations in the rear of Lee had disconcerted and alarmed that general so much as to aid materially in forcing his retrograde march, and both acknowledged that, by drawing off the enemy's cavalry during the past fortnight, we had enabled them to move the Army of the Potomac and its enormous trains without molestation in the manoeuvres that had carried it to the North Anna. Then, too, great quantities of provisions and munitions of war had been destroyed—stores that the enemy had accumulated at sub-depots from strained resources and by difficult means; the railroads that connected Lee with Richmond broken, the most successful cavalry leader of the South killed, and in addition to all this there had been inflicted on the Confederate mounted troops the most thorough defeat that had yet befallen them in Virginia.
