absolutely
successful. He undertook at once to find vessels of light draught
to carry our supplies from Port Royal to Cheeves's Mill, or to
Grog's Bridge above, whence they could be hauled by wagons to our
several camps; he offered to return with me to Fort McAllister, to
superintend the removal of the torpedoes, and to relieve me of all
the details of this most difficult work. General Foster then
concluded to go on to Port Royal, to send back to us six hundred
thousand rations, and all the rifled guns of heavy calibre, and
ammunition on hand, with which I thought we could reach the city of
Savannah, from the positions already secured. Admiral Dahlgren
then returned with me in the Harvest Moon to Fort McAllister. This
consumed all of the 14th of December; and by the 15th I had again
reached Cheeves's Mill, where my horse awaited me, and rode on to
General Howard's headquarters at Anderson's plantation, on the
plank-road, about eight miles back of Savannah. I reached this
place about noon, and immediately sent orders to my own
head-quarters, on the Louisville road, to have them brought over to
the plank-road, as a place more central and convenient; gave written
notice to Generals Slocum and Howard of all the steps taken, and
ordered them to get ready to receive the siege-guns, to put them in
position to bombard Savannah, and to prepare for the general assault.
The country back of Savannah is very low, and intersected with
innumerable saltwater creeks, swamps, and rice-fields. Fortunately
the weather was good and the roads were passable, but, should the
winter rains set in, I knew that we would be much embarrassed.
Therefore, heavy details of men were at once put to work to prepare a
wharf and depot at Grog's Bridge, and the roads leading thereto were
corduroyed in advance. The Ogeechee Canal was also cleared out for
use; and boats, such as were common on the river plantations, were
collected, in which to float stores from our proposed base on the
Ogeechee to the points most convenient to the several camps.

Slocum's wing extended from the Savannah River to the canal, and
Howard's wing from the canal to the extreme right, along down the
Little Ogeechee. The enemy occupied not only the city itself, with
its long line of outer works, but the many forts which had been
built to guard the approaches from the sea-such as at Beaulieu,
Rosedew, White Bluff, Bonaventura, Thunderbolt, Cansten's Bluff,
Forts Tatnall, Boggs,
