happening to be at
City Point, was sent out to supersede General Thomas; luckily for
the latter, he acted in time, gained a magnificent victory, and
thus escaped so terrible a fate.

On the 18th of December, at my camp by the side of the plank-road,
eight miles back of Savannah, I received General Hardee's letter
declining to surrender, when nothing remained but to assault. The
ground was difficult, and, as all former assaults had proved so
bloody, I concluded to make one more effort to completely surround
Savannah on all aides, so as further to excite Hardee's fears, and,
in case of success, to capture the whole of his army. We had
already completely invested the place on the north, west, and
south, but there remained to the enemy, on the east, the use of the
old dike or plank-road leading into South Carolina, and I knew that
Hardee would have a pontoon-bridge across the river. On examining
my maps, I thought that the division of John P. Hatch, belonging to
General Fosters command, might be moved from its then position at
Broad River, by water, down to Bluffton, from which it could reach
this plank-road, fortify and hold it--at some risk, of course,
because Hardee could avail himself of his central position to fall
on this detachment with his whole army. I did not want to make a
mistake like "Ball's Bluff" at that period of the war; so, taking
one or two of my personal staff, I rode back to Grog's Bridge,
leaving with Generals Howard and Slocum orders to make all
possible preparations, but not to attack, during my two or three
days' absence; and there I took a boat for Wassaw Sound, whence
Admiral Dahlgren conveyed me in his own boat (the Harvest Moon) to
Hilton Head, where I represented the matter to General Foster, and
he promptly agreed to give his personal attention to it. During
the night of the 20th we started back, the wind blowing strong,
Admiral Dahlgren ordered the pilot of the Harvest Moon to run into
Tybee, and to work his way through to Wassaw Sound and the Ogeechee
River by the Romney Marshes. We were caught by a low tide and
stuck in the mud. After laboring some time, the admiral ordered
out his barge; in it we pulled through this intricate and shallow
channel, and toward evening of December 21st we discovered, coming
toward us, a tug, called the Red Legs, belonging to the
Quarter-master's Department, with a staff-officer on board, bearing
letters from Colonel Dayton to myself and the admiral, r
