After dark, our own and the Confederate dead having been buried, I withdrew, and moving to the rear of our infantry, marched all night and till I reached the vicinity of Old Church, where I had been instructed to keep a vigilant watch on the enemy with Gregg's and Torbert's divisi6ns. As soon as I had taken position at Old Church my pickets were pushed out in the direction of Cold Harbor, and the fact that the enemy was holding that point in some force was clearly ascertained. But our occupation of Cold Harbor was of the utmost importance; indeed, it was absolutely necessary that we should possess it, to secure our communications with the White House, as well as to cover the extension of our line to the left toward the James River. Roads from Bethesda Church, Old Church, and the White House centred at Cold Harbor, and from there many roads diverged also toward different crossings of the Chickahominy, which were indispensable to us.
The enemy too realized the importance of the place, for as soon as he found himself compelled to take up the line of the Tolopotomy he threw a body of troops into Cold Harbor by forced marches, and followed it up by pushing a part of this force out on the Old Church road as far as Matadequin Creek, where he established a line of battle, arranging the front of it parallel to the road along the south bank of the Pamunkey; this for the purpose of endangering our trains as they moved back and forth between the army and the White House.
Meanwhile I had occupied Old Church and pushed pickets down toward Cold Harbor. The outposts struck each other just north of Matadequin Creek, and a spirited fight immediately took place. At first our pickets were sorely pressed, but Torbert, who was already preparing to make a reconnoissance, lost no time in reinforcing them on the north side of the creek with Devin's brigade. The fight then became general, both sides, dismounted, stubbornly contesting the ground.
Of the Confederates, General Butler's South Carolinians bore the brunt of the fight, and, strongly posted as they were on the south bank of the creek, held their ground with the same obstinacy they had previously shown at Hawe's Shop. Finally, however, Torbert threw Merritt's and Custer's brigades into the action, and the enemy retired, we pursuing to within a mile and a half of Cold Harbor and capturing a number of prisoners. Gregg's division took no part in the actual fighting, but remained near Old Church observing the roads on Torberts flanks, one leading toward Bethesda Church on his right, the other to his left in the direction of the White House. This latter road Gregg was particularly instructed to keep open, so as to communicate with General W. F. Smith, who was then debarking his corps at the White House, and on the morning of the 3ist this general's advance was covered by a brigade which Gregg had sent him for the purpose.
Torbert having pursued toward Cold Harbor the troops he fought at Matadequin Creek, had taken up a position about a mile and a half from that place, on the Old Church road. The morning of the 31st I visited him to arrange for his further advance, intending thus to anticipate an expected attack from Fitzhugh Lee, who was being reinforced by infantry. I met Torbert at Custer's headquarters, and found that the two had already been talking over a scheme to capture Cold Harbor, and when their plan was laid before me it appeared so plainly feasible that I fully endorsed it, at once giving directions for its immediate execution, and ordering Gregg to come forward to Torbert's support with such troops as he could spare from the duty with which he had been charged.
Torbert moved out promptly, Merritt's brigade first, followed by Custer's, on the direct road to Cold Harbor, while Devin's brigade was detached, and marched by a left-hand road that would bring him in on the right and rear of the enemy's line, which was posted in front of the crossroads. Devin was unable to carry his part of the programme farther than to reach the front of the Confederate right, and as Merritt came into position to the right of the Old Church road Torbert was obliged to place a part of Custer's brigade on Merritt's left so as to connect with Devin. The whole division was now in line, confronted by Fitzhugh Lee's cavalry, supported by Clingman's brigade from Hoke's division of infantry; and from the Confederate breastworks, hastily constructed out of logs, rails, and earth, a heavy fire was already being poured upon us that it seemed impossible to withstand. None of Gregg's division had yet arrived, and so stubborn was the enemy's resistance that I began to doubt our ability to carry the place before reinforcements came up, but just then Merritt reported that he could turn the enemy's left, and being directed to execute his proposition, he carried it to a most successful issue with the First and Second regular cavalry. Just as these two regiments passed around the enemy's left and attacked his rear, the remainder of the division assailed him in front. This manoeuvre of Merritt's stampeded the Confederates, and the defenses falling into our hands easily, we pushed ahead on the Bottom's bridge road three-fourths of a mile beyond Cold Harbor.
