When news of Sherman being in possession of Savannah reached the North, distinguished statesmen and visitors began to pour in to see him.  Among others who went was the Secretary of War, who seemed much pleased at the result of his campaign.  Mr. Draper, the collector of customs of New York, who was with Mr. Stanton’s party, was put in charge of the public property that had been abandoned and captured.  Savannah was then turned over to General Foster’s command to hold, so that Sherman might have his own entire army free to operate as might be decided upon in the future.  I sent the chief engineer of the Army of the Potomac (General Barnard) with letters to General Sherman.  He remained some time with the general, and when he returned brought back letters, one of which contained suggestions from Sherman as to what ought to be done in co-operation with him, when he should have started upon his march northward.

I must not neglect to state here the fact that I had no idea originally of having Sherman march from Savannah to Richmond, or even to North Carolina.  The season was bad, the roads impassable for anything except such an army as he had, and I should not have thought of ordering such a move.  I had, therefore, made preparations to collect transports to carry Sherman and his army around to the James River by water, and so informed him.  On receiving this letter he went to work immediately to prepare for the move, but seeing that it would require a long time to collect the transports, he suggested the idea then of marching up north through the Carolinas.  I was only too happy to approve this; for if successful, it promised every advantage.  His march through Georgia had thoroughly destroyed all lines of transportation in that State, and had completely cut the enemy off from all sources of supply to the west of it.  If North and South Carolina were rendered helpless so far as capacity for feeding Lee’s army was concerned, the Confederate garrison at Richmond would be reduced in territory, from which to draw supplies, to very narrow limits in the State of Virginia; and, although that section of the country was fertile, it was already well exhausted of both forage and food.  I approved Sherman’s suggestion therefore at once.

The work of preparation was tedious, because supplies, to load the wagons for the march, had to be brought from a long distance.  Sherman would now have to march through a country furnishing fewer provisions than that he had previously been operating in during his march to the sea.  Besides, he was confronting, or marching toward, a force of the enemy vastly superior to any his troops had encountered on their previous march; and the territory through which he had to pass had now become of such vast importance to the very existence of the Confederate army, that the most desperate efforts were to be expected in order to save it.

Sherman, therefore, while collecting the necessary supplies to start with, made arrangements with Admiral Dahlgren, who commanded that part of the navy on the South Carolina and Georgia coast, and General Foster, commanding the troops, to take positions, and hold a few points on the sea coast, which he (Sherman) designated, in the neighborhood of Charleston.
