After Custer’s charge, the Confederate cavalry was badly broken up, the main portion of it being driven in a rout toward Ashland and a small part in the direction of Richmond, which latter force finally rejoined Fitzhugh Lee near Mechanicsville.  A reconnoitring party being now sent up the Brook turnpike toward the city, dashed across the South Fork of the Chickahominy, drove a small force from the enemy’s exterior intrenchments and went within them.  I followed this party, and after a little exploration found between the two lines of works a country road that led across to the pike which runs from Mechanicsville to Richmond.  I thought we could go around within the outer line of works by this country road across to the Mechanicsville pike on the south side of the Chickahominy, and encamp the next night at Fair Oaks; so I determined to make the movement after dark, being influenced in this to some extent by reports received during the afternoon from colored people, to the effect that General B. F. Butler’s army had reached a small stream on the south side of the James, about four miles south of Richmond.  If I could succeed in getting through by this road, not only would I have a shorter line of march to Haxall’s landing, but there was also a possibility that I could help Butler somewhat by joining him so near Richmond.  Therefore, after making the wounded as comfortable as possible, we commenced the march about 11 o’clock on the night of the 1lth, and massed the command on the plateau south of the Meadow bridge near daylight on the 12th.

The enemy, anticipating that I would march by this route, had planted torpedoes along it, and many of these exploded as the column passed over them, killing several horses and wounding a few men, but beyond this we met with no molestation.  The torpedoes were loaded shells planted on each side of the road, and so connected by wires attached to friction-tubes in the shells, that when a horse’s hoof struck a wire the shell was exploded by the jerk on the improvised lanyard.  After the loss of several horses and the wounding of some of the men by these torpedoes, I gave directions to have them removed, if practicable, so about twenty-five of the prisoners were brought up and made to get down on their knees, feel for the wires in the darkness, follow them up and unearth the shells.  The prisoners reported the owner of one of the neighboring houses to be the principal person who had engaged in planting these shells, and I therefore directed that some of them be carried and placed in the cellar of his house, arranged to explode if the enemy’s column came that way, while he and his family were brought off as prisoners and held till after daylight.

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.
