"The Seventeenth Corps took up the destruction of the railroad at the Ogeechee, near Station No. 10, and continued it to Millen; the enemy offering little or no opposition, although preparation had seemingly been made at Millen."

"On the 3d of December the 17th Corps which I accompanied, was at Millon; the 15th Corps, General Howard, was south of the Ogeechee, opposite Station No. 7 (Scarboro); the 20th Corps, General Slocum, on the Augusta Railroad, about four miles north of Millen, near Buckhead Church, and the 14th Corps, General Jeff. C. Davis, in the neighborhood of Lumpkin's Station, on the Augusta Railroad. All were ordered to march in the direction of Savannah—the 15th Corps to continue south of the Ogeechee, the 17th to destroy the railroad as far as Ogeechee Church—and four days were allowed to reach the line from Ogeechee Church to the neighborhood of Halley's Ferry, on the Savannah River. All the columns reached their destinations in time, and continued to march on their several roads—General Davis following the Savannah River road, General Slocum the middle road by way of Springfield, General Blair the railroad, and General Howard still south and west of the Ogeechee, with orders to cross to the east bank opposite 'Eden Station,' or Station No. 2.

"As we approached Savannah the country became more marshy and difficult, and more obstructions were met, in the way of felled trees, where the roads crossed the creek swamps or narrow causeways; but our pioneer companies were well organized, and removed the obstructions in an incredibly short time. No opposition from the enemy worth speaking of was encountered until the heads of columns were within 15 miles of Savannah, where all the roads leading to the city were obstructed more or less by felled timber, with earthworks, and artillery. But these were easily turned and the enemy driven away, so that by the 10th of December the enemy was driven within his lines at Savannah. These followed substantially a swampy creek which empties into the Savannah River about three miles above the city, across to the head of a corresponding stream which empties into the Little Ogeechee. These streams were singularly favorable to the enemy as a cover, being very marshy, and bordered by rice-fields, which were flooded either by the tide-water or by inland ponds, the gates to which were controlled and covered by his heavy artillery.

"The only approaches to the city were by five narrow causeways, namely, the two railroads, and the Augusta, the Louisville, and the Ogeechee dirt roads; all of which were commanded by heavy ordnance, too strong for us to fight with our light field guns. To assault an enemy of unknown strength at such a disadvantage appeared to me unwise, especially as I had so successfully brought my army, almost unscathed, so great a distance, and could surely attain the same result by the operation of time. I therefore instructed my army commanders to closely invest the city from the north and west, and to reconnoitre well the ground in their fronts, respectively, while I gave my personal attention to opening communication with our fleet, which I knew was waiting for us in Tybee, Warsaw, and Ossabaw Sounds.

"In approaching Savannah, General Slocum struck the Charleston Railroad near the bridge, and occupied the river bank as his left flank, where he had captured two of the enemy's river boats, and had prevented two others (gunboats) from coming down the river to communicate with the city; while General Howard, by his right flank, had broken the Gulf Railroad at Fleming's and way stations, and occupied the railroad itself down to the Little Ogeechee, near 'Station No. 1;' so that no supplies could reach Savannah by any of its accustomed channels. We, on the contrary, possessed large herds of cattle, which we had brought along or gathered in the country, and our wagons still contained a reasonable amount of breadstuffs and other necessaries, and the fine rice crops of the Savannah and Ogeechee Rivers furnished to our men and animals a large amount of rice and rice straw. We also held the country to the south and west of the Ogeechee as foraging ground. Still, communication with the fleet was of vital importance, and I directed General Kilpatrick to cross the Ogeechee by a pontoon bridge, to reconnoitre Fort McAllister, and to proceed to Catherine's Sound, in the direction of Sunbury or Kilkenny Bluff, and open communication with the fleet. General Howard had previously by my direction sent one of his best scouts down the Ogeechee in a canoe for a like purpose. But more than this was necessary. We wanted the vessels and their contents, and the Ogeechee River, a navigable stream, close to the rear of our camps, was the proper avenue of supply.

"The enemy had burned the road-bridge across the Ogeechee, just below the mouth of the Canoochee, known as 'King's bridge.' This was reconstructed in an incredibly short time, in the most substantial manner, by the 58th Indiana, Colonel Buel, under the direction of Captain Reese, of the Engineers' Corps, and on the 13th of December the 2d Division of the 15th Corps, under command of Brigadier-General Hazen, crossed the bridge to the west bank of the Ogeechee and marched down with orders to carry by assault Fort McAllister, a strong inclosed redoubt, manned by two companies of artillery and three of infantry, in all about two hundred men, and mounting 23 guns en barbette, and one mortar. General Hazen reached the vicinity of Fort McAllister about 1 P. M., deployed his division about that place, with both flanks resting upon the river, posted his skirmishers judiciously behind the trunks of trees whose branches had been used for abattis, and about 5 P. M., assaulted the place with nine regiments at three points; all of them successful. I witnessed the assault from a rice-mill on the opposite bank of the river, and can bear testimony to the handsome manner in which it was accomplished.

"Up to this time we had not communicated with our fleet. From the signal station at the rice-mill our officers had looked for two days over the rice-fields and salt marsh in the direction of Ossabaw Sound, but could see nothing of it. But while watching the preparations for the assault on Fort McAllister, we discovered in the distance what seemed to be the smoke-stack of a steamer, which became more and more distinct. Until about the very moment of the assault she was plainly visible below the fort, and our signal was answered. As soon as I saw our colors fairly planted upon the walls of McAllister, in company with General Howard I went in a small boat down to the fort and met General Hazen, who had not yet communicated with the gunboat below, as it was shut out to him by a point of timber. Determined to communicate that night, I got another small boat and a crew and pulled down the river till I found the tug 'Dandelion,' Captain Williamson, U. S. N., who informed me that Captain Duncan, who had been sent by General Howard, had succeeded in reaching Admiral Dahlgren and General Foster, and that he was expecting them hourly in Ossabaw Sound. After making communications to those officers, and a short communication to the War Department, I returned to Fort McAllister that night, and before daylight was overtaken by Major Strong, of General Foster's staff, advising me that General Foster had arrived in the Ogeechee, near Fort McAllister, and was very anxious to meet me on board his boat. I accordingly returned with him, and met General Foster on board the steamer 'Nemeha,' and, after consultation, determined to proceed with him down the sound in hopes to meet Admiral Dahlgren. But we did not meet him until we reached Warsaw Sound, about noon. I there went on board the Admiral's flag-ship, the 'Harvest Moon,' after having arranged with General Foster to send us from Hilton Head some siege ordnance and some boats suitable for navigating the Ogeechee River. Admiral Dahlgren very kindly furnished me with all the data concerning his fleet and the numerous forts that guarded the inland channels between the sea and Savannah. I explained to him how completely Savannah was invested at all points, save only the plank road on the South Carolina shore known as the 'Union Causeway,' which I thought I could reach from my left flank across the Savannah River. I explained to him that if he would simply engage the attention of the forts along Wilmington Channel, at Beaulieu and Rosedew, I thought I could carry the defenses of Savannah by assault as soon as the heavy ordnance arrived from Hilton Head. On the 15th the Admiral carried me back to Fort McAllister, whence I returned to our lines in the rear of Savannah.

"Having received and carefully considered all the reports of division commanders, I determined to assault the lines of the enemy as soon as my heavy ordnance came from Port Royal, first making a formal demand for surrender. On the 17th, a number of thirty-pounder Parrott guns having reached King's Bridge, I proceeded in person to the headquarters of Major-General Slocum, on the Augusta Road, and dispatched thence into Savannah, by flag of truce, a formal demand for the surrender of the place; and on the following day received an answer from General Hardee refusing to surrender.

"In the meantime further reconnoissances from our left flank had demonstrated that it was impracticable or unwise to push any considerable force across the Savannah River, for the enemy held the river opposite the city with iron-clad gunboats, and could destroy any pontoons laid down by us between Hutchinson's Island and the South Carolina shore, which would isolate any force sent over from that flank. I therefore ordered General Slocum to get into position the siege guns and make all the preparations necessary to assault, and to report to me the earliest moment when he could be ready, while I should proceed rapidly round by the right and make arrangements to occupy the Union Causeway from the direction of Port Royal. General Foster had already established a division of troops on the peninsula or neck between the Coosawatchie and Tullifinney Rivers, at the head of Broad River, from which position he could reach the railroad with his artillery.

"I went to Port Royal in person, and made arrangements to reinforce that command by one or more divisions, under a proper officer, to assault and carry the railroad, and thence turn toward Savannah until it occupied the causeway in question. I went on board the Admiral's flagship, the 'Harvest Moon,' which put out to sea the night of the 20th. But the wind was high, and increased during the night, so that the pilot judged Ossabaw bar impassable, and ran into the Tybee, whence we proceeded through the inland channels into Warsaw Sound, and thence through Romney Marsh. But the ebb tide caught the 'Harvest Moon' and she was unable to make the passage. Admiral Dahlgren took me in his barge, and pulling in the direction of Vernon River we met the army tug 'Red Legs,' bearing a message from my Adjutant, Captain Dayton, of that morning, the 21st, to the effect that our troops were in possession of the enemy's lines, and were advancing without opposition into Savannah, the enemy having evacuated the place during the previous night.
