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, etc., etc. I knew that General Hardee could
not have a garrison strong enough for all these purposes, and I was
therefore anxious to break his lines before he could receive
reenforcements from Virginia or Augusta. General Slocum had
already captured a couple of steamboats trying to pass down the
Savannah River from Augusta, and had established some of his men on
Argyle and Hutchinson Islands above the city, and wanted to
transfer a whole corps to the South Carolina bank; but, as the
enemy had iron-clad gunboats in the river, I did not deem it
prudent, because the same result could be better accomplished from
General Fosters position at Broad River.

Fort McAllister was captured as described, late in the evening of
December 13th, and by the 16th many steamboats had passed up as
high as King's Bridge; among them one which General Grant had
dispatched with the mails for the army, which had accumulated since
our departure from Atlanta, under charge of Colonel A. H. Markland.
These mails were most welcome to all the officers and soldiers of
the army, which had been cut off from friends and the world for two
months, and this prompt receipt of letters from home had an
excellent effect, making us feel that home was near. By this
vessel also came Lieutenant Dune, aide-de-camp, with the following
letter of December 3d, from General Grant, and on the next day
Colonel Babcock, United States Engineers, arrived with the letter
of December 6th, both of which are in General Grant's own
handwriting, and are given entire:

HEADQUARTERS ARMIES OF THE UNITED STATES
CITY POINT, VIRGINIA, December 3, 1864.

Major-General W. T. SHERMAN, commanding Armies near Savannah,
Georgia.

GENERAL: The little information gleaned from the Southern press
indicating no great obstacle to your progress, I have directed your
mails (which had been previously collected in Baltimore by Colonel
Markland, special-agent of the Post-Office Department) to be sent
as far as the blockading squadron off Savannah, to be forwarded to
you as soon as heard from on the coast.

Not liking to rejoice before the victory is assured, I abstain from
congratulating you and those under your command, until bottom has
been struck. I have never had a fear, however,
