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.

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.
