By the 6th of June General Grant again determined to continue the movement of the army by its left flank to the south bank of the James River, his unsuccessful attack on the enemy’s works near Cold Harbor having demonstrated that Lee’s position north of the Chickahominy could not be carried by assault with results that would compensate for the enormous loss of life which must follow; therefore a further attempt to fight a decisive battle north of Richmond was abandoned.  In carrying the army to the James River the hazardous manoeuvres would be hampered by many obstacles, such as the thick timber, underbrush, and troublesome swamps to be met in crossing the Chickahominy.  Besides, Lee held an interior line, from which all the direct roads to Richmond could be covered with his infantry, leaving his cavalry free to confront our advance on the south bank of the Chickahominy as far down as Jones’s bridge, and thence around to Charles City Court House.  In view of these difficulties it became necessary to draw off the bulk of the enemy’s cavalry while the movement to the James was in process of execution, and General Meade determined to do this by requiring me to proceed with two divisions as far as Charlottesville to destroy the railroad bridge over the Rivanna River near that town, the railroad itself from the Rivanna to Gordonsville, and, if practicable, from Gordonsville back toward Hanover Junction also.

“With two divisions of your corps you will move on the morning of the 7th instant to Charlottesville and destroy the railroad bridge over the Rivanna near that town; you will then thoroughly destroy the railroad from that point to Gordonsville, and from Gordonsville toward Hanover Junction, and to the latter point, if practicable.  The chief engineer, Major Duane, will furnish you a canvas pontoon-train of eight boats.  The chief quartermaster will supply you with such tools, implements, and materials as you may require for the destruction of the road.  Upon the completion of this duty you will rejoin this army.

After Meade’s instructions reached me they were somewhat modified by General Grant, who on the same evening had received information that General Hunter, commanding the troops in West Virginia, had reached Staunton and engaged with advantage the Confederate commander, General Jones, near that place.  General Grant informed me orally that he had directed Hunter to advance as far as Charlottesville, that he expected
