to Lee’s army, and on every hand there were indications that the Confederate Government wished to hold it at least until after the crops could be gathered in to their depots at Lynchburg and Richmond.  Its retention, besides being of great advantage in the matter of supplies, would also be a menace to the North difficult for General Grant to explain, and thereby add an element of considerable benefit to the Confederate cause; so when Early’s troops again appeared at Martinsburg it was necessary for General Grant to confront them with a force strong enough to put an end to incursions north of the Potomac, which hitherto had always led to National discomfiture at some critical juncture, by turning our army in eastern Virginia from its chief purpose—­the destruction of Lee and the capture of the Confederate capital.

This second irruption of Early, and his ruthless destruction of Chambersburg led to many recommendations on the part of General Grant looking to a speedy elimination of the confusion then existing among the Union forces along the upper Potomac, but for a time the authorities at Washington would approve none of his propositions.  The President and Secretary Stanton seemed unwilling to adopt his suggestions, and one measure which he deemed very important—­the consolidation into a single command of the four geographical districts into which, to relieve political pressure no doubt, the territory had been divided—­met with serious opposition.  Despite Grant’s representations, he could not prevail on the Administration to approve this measure, but finally the manoeuvres of Early and the raid to Chambersburg compelled a partial compliance, though Grant had somewhat circumvented the difficulty already by deciding to appoint a commander for the forces in the field that were to operate against Early.

On the 31st of July General Grant selected me as this commander, and in obedience to his telegraphic summons I repaired to his headquarters at City Point.  In the interview that followed, he detailed to me the situation of affairs on the upper Potomac, telling me that I was to command in the field the troops that were to operate against Early, but that General Hunter, who was at the head of the geographical department, would be continued in his position for the reason that the Administration was reluctant to reconstruct or consolidate the different districts.  After informing me that one division of the Cavalry Corps would be sent to my new command, he went on to say that he wanted me to push the enemy as soon as this division arrived, and if Early retired up the Shenandoah Valley I was to pursue, but if he crossed the Potomac I was to put myself south of him and try to compass his destruction.  The interview having ended, I returned to Hancock Station to prepare for my departure, and on the evening of August 1 I was relieved from immediate duty with the Army of the Potomac, but not from command of the cavalry as a corps organization.
