All these ideas are given in my answer to General Grant's letters (dated December 16, 1864) herewith, which is a little more full than the one printed in the report of the Committee on the Conduct of the War, because in that copy I omitted the matter concerning General Thomas, which now need no longer be withheld: HEADQUARTERS MILITARY DIVISION OF THE MISSISSIPPI, IN THE FIELD, NEAR SAVANNAH, December 16, 1864.
Lieutenant-General U.S.GRANT, Commander-in-Chief, City Point, Virginia.
GENERAL: I received, day before yesterday, at the hands of Lieutenant Dunn, your letter of December 8d, and last night, at the hands of Colonel Babcock, that of December 6th.

I had previously made you a hasty scrawl from the tugboat Dandelion, in Ogeechee River, advising you that the army had reached the sea-coast, destroying all the railroads across the State of Georgia, investing closely the city of Savannah, and had made connection with the fleet.
Since writing that note, I have in person met and conferred with General Foster and Admiral Dahlgren, and made all the arrangements which were deemed essential for reducing the city of Savannah to our possession.

But, since the receipt of yours of the 6th, I have initiated measures looking principally to coming to you with fifty or Sixty thousand infantry, and incidentally to capture Savannah, if time will allow.
At the time we carried Fort McAllister by assault so handsomely, with its twenty-two guns and entire garrison, I was hardly aware of its importance; but, since passing down the river with General Foster and up with Admiral Dahlgren, I realize how admirably adapted are Ossabaw Sound and Ogeechee River to supply an army operating against Savannah.

Seagoing vessels can easily come to King's Bridge, a point on Ogeechee River, fourteen and a half miles due west of Savannah, from which point we have roads leading to all our camps.

The country is low and sandy, and cut up with marshes, which in wet weather will be very bad, but we have been so favored with weather that they are all now comparatively good, and heavy details are constantly employed in double-corduroying the marshes, so that I have no fears even of bad weather.
