“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 me to unite with him there, and that the two commands, after destroying the James River canal and the Virginia Central road, were to join the Army of the Potomac in the manner contemplated in my instructions from General Meade; and that in view of what was anticipated, it would be well to break up as much of the railroad as possible on my way westward.  A copy of his letter to Hunter comprised my written instructions.  A junction with this general was not contemplated when the expedition was first conceived, but became an important though not the paramount object after the reception of the later information.  The diversion of the enemy’s cavalry from the south side of the Chickahominy was its main purpose, for in the presence of such a force as Lee’s contracted lines would now permit him to concentrate behind the Chickahominy, the difficulties of crossing that stream would be largely increased if he also had at hand a strong body of horse, to gain the time necessary for him to oppose the movement at the different crossings with masses of his infantry.

The order calling for two divisions for the expedition, I decided to take Gregg’s and Torbert’s, leaving Wilson’s behind to continue with the infantry in its march to the James and to receive instructions directly from, the headquarters of the army.  All my dismounted men had been sent to the White House some days before, and they were directed to report to Wilson as they could be provided with mounts.
