At that time the weather was cold and sleety, the ground was covered with ice and snow, and both parties for a time rested on the defensive.  Those matters stood at Nashville, while we were closing down on Savannah, in the early part of December, 1864; and the country, as well as General Grant, was alarmed at the seeming passive conduct of General Thomas; and General Grant at one time considered the situation so dangerous that he thought of going to Nashville in person, but General John A. Logan, 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, reporting that the city of Savannah had been found
