Meanwhile the most intense excitement prevailed in Richmond. The Confederates, supposing that their capital was my objective point, were straining every effort to put it in a state of defense, and had collected between four and five thousand irregular troops, under General Bragg, besides bringing up three brigades of infantry from the force confronting General Butler south of the James River, the alarm being intensified by the retreat, after the defeat at Yellow Tavern, of Stuart's cavalry, now under General Fitzhugh Lee, by way of Ashland to Mechanicsville, on the north side of the Chickahominy, for falling back in that direction, left me between them and Richmond.
Our march during the night of the 11th was very tedious, on account of the extreme darkness and frequent showers of rain; but at daylight on the 12th the head of my column, under Wilson, reached the Mechanicsville pike. Here Wilson, encountering the enemy's works and batteries manned by General Bragg's troops, endeavored to pass. In this he failed, and as soon as I was notified that it was impracticable to reach Fair Oaks by passing between the works and the Chickahominy, Custer's brigade was directed to make the crossing to the north side of the Chickahominy, at the Meadow bridge. Custer moved rapidly for the bridge, but found it destroyed, and that the enemy's cavalry was posted on the north side, in front of Mechanicsville. When this information came back, I ordered Merritt to take his whole division and repair the bridge, instructing him that the crossing must be made at all hazards; for, in view of an impending attack by the enemy's infantry in Richmond, it was necessary that I should have the bridge as a means of egress in case of serious disaster.
All the time that Merritt was occupied in this important duty, the enemy gave great annoyance to the working party by sweeping the bridge with a section of artillery and a fire from the supporting troops, so a small force was thrown across to drive them away. When Merritt had passed two regiments over, they attacked, but were repulsed. The work on the, bridge continued, however, not-withstanding this discomfiture; and when it was finished, Merritt crossed nearly all his division, dismounted, and again attacked the enemy, this time carrying the line, of temporary breastworks, built with logs and rails, and pursuing his broken troops toward Gaines's Mills.
While Merritt was engaged in this affair, the Confederates advanced from behind their works at Richmond, and attacked Wilson and Gregg.
Wilson's troops were driven back in some confusion at first; but Gregg, in anticipation of attack, had hidden a heavy line of dismounted men in a bushy ravine on his front, and when the enemy marched upon it, with much display and under the eye of the President of the Confederacy, this concealed line opened a destructive fire with repeating carbines; and at the same time the batteries of horse-artillery, under Captain Robinson, joining in the contest, belched forth shot and shell with fatal effect. The galling fire caused the enemy to falter, and while still wavering Wilson rallied his men, and turning some of them against the right flank of the Confederates, broke their line, and compelled them to withdraw for security behind the heavy works thrown up for the defense of the city in 1862.
By destroying the Meadow bridge and impeding my column on the Mechanicsville, pike, the enemy thought to corner us completely, for he still maintained the force in Gregg's rear that had pressed it the day before; but the repulse of his infantry ended all his hopes of doing us any serious damage on the limited ground between the defenses of Richmond and the Chickahominy. He felt certain that on account of the recent heavy rains we could not cross the Chickahominy except by the Meadow bridge, and it also seemed clear to him that we could not pass between the river and his intrenchments; therefore he hoped to ruin us, or at least compel us to return by the same route we had taken in coming, in which case we would run into Gordon's brigade, but the signal repulse of Bragg's infantry dispelled these illusions.
Even had it not been our good fortune to defeat him, we could have crossed the Chickahominy if necessary at several points that were discovered by scouting parties which, while the engagement was going on, I had sent out to look up fords. This means of getting out from the circumscribed plateau I did not wish to use, however, unless there was no alternative, for I wished to demonstrate to the Cavalry Corps the impossibility of the enemy's destroying or capturing so large a body of mounted troops.
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.
