Charles City Court House on the James River, June 14, 1864. It was with infinite relief that Grant saw the advance of the Army of the Potomac reach this point on June 14th. His last flanking movement was an extremely hazardous one. More than fifty miles intervened between him and Butler by the roads he would have to travel, and he had to cross both the Chickahominy and the James, which were unbridged. The paramount difficulty was to get the Army of the Potomac out of its position before Lee, who confronted it at Cold Harbor. Lee had the shorter line and better roads to move over and meet Grant at the Chickahominy, or he might, if he chose, descend rapidly on Butler and crush him before Grant could unite with him. "But," says Grant, "the move had to be made, and I relied upon Lee's not seeing my danger as I saw it." Near the old Charles City Court House the crossing of the James was successfully accomplished, and on the 14th Grant took steamer and ran up the river to Bermuda Hundred to see General Butler and direct the movement against Petersburg, that began the final investment of that city.

A._] TO ATLANTA Johnston was an officer who, by the common consent of the military men of both sides, was reckoned second only to Lee, if second, in the qualities which fit an officer for the responsibility of great commands.... He practised a lynx-eyed watchfulness of his adversary, tempting him constantly to assault his entrenchments, holding his fortified positions to the last moment, but choosing that last moment so well as to save nearly every gun and wagon in the final withdrawal, and always presenting a front covered by such defenses that one man in the line was, by all sound military rules, equal to three or four in the attack. In this way he constantly neutralized the superiority of force his opponent wielded, and made his campaign from Dalton to the Chattahoochee a model of defensive warfare. It is Sherman's glory that, with a totally different temperament, he accepted his adversary's game, and played it with a skill that was finally successful, as we shall see.--_Major-General Jacob D. Cox, U. S. V., in "Atlanta."_ The two leading Federal generals of the war, Grant and Sherman, met at Nashville, Tennessee, on March 17, 1864, and arranged for a great concerted double movement against the two main Southern armies, the Army of Northern Virginia and the Army of Tennessee. Grant, who had been made commander of all the Federal armies, was to take personal charge of the Army of the Potomac and move against Lee, while to Sherman, whom, at Grant's request, President Lincoln had placed at the head of the Military Division of the Mississippi, he turned over the Western army, which was to proceed against Johnston.
