Soon after General Sherman commenced his march from Atlanta, two expeditions, one from Baton Rouge, Louisiana, and one from Vicksburg, Mississippi, were started by General Canby to cut the enemy's lines of communication with Mobile and detain troops in that field. General Foster, commanding Department of the South, also sent an expedition, via Broad River, to destroy the railroad between Charleston and Savannah. The expedition from Vicksburg, under command of Brevet Brigadier-General E. D. Osband (colonel 3d United States colored cavalry), captured, on the 27th of November, and destroyed the Mississippi Central Railroad bridge and trestle-work over Big Black River, near Canton, thirty miles of the road, and two locomotives, besides large amounts of stores. The expedition from Baton Rouge was without favorable results. The expedition from the Department of the South, under the immediate command of Brigadier-General John P. Hatch, consisting of about five thousand men of all arms, including a brigade from the navy, proceeded up Broad River and debarked at Boyd's Neck on the 29th of November, from where it moved to strike the railroad at Grahamsville. At Honey Hill, about three miles from Grahamsville, the enemy was found and attacked in a strongly fortified position, which resulted, after severe fighting, in our repulse with a loss of seven hundred and forty-six in killed, wounded, and missing. During the night General Hatch withdrew. On the 6th of December General Foster obtained a position covering the Charleston and Savannah Railroad, between the Coosawhatchie and Tulifinny rivers.
Hood, instead of following Sherman, continued his move northward, which seemed to me to be leading to his certain doom. At all events, had I had the power to command both armies, I should not have changed the orders under which he seemed to be acting. On the 26th of October, the advance of Hood's army attacked the garrison at Decatur, Alabama, but failing to carry the place, withdrew towards Courtland, and succeeded, in the face of our cavalry, in effecting a lodgment on the north side of the Tennessee River, near Florence. On the 28th, Forrest reached the Tennessee, at Fort Heiman, and captured a gunboat and three transports. On the 2d of November he planted batteries above and below Johnsonville, on the opposite side of the river, isolating three gunboats and eight transports. On the 4th the enemy opened his batteries upon the place, and was replied to from the gunboats and the garrison. The gunboats becoming disabled were set on fire, as also were the transports, to prevent their falling into the hands of the enemy. About a million and a half dollars' worth of store and property on the levee and in storehouses was consumed by fire. On the 5th the enemy disappeared and crossed to the north side of the Tennessee River, above Johnsonville, moving towards Clifton, and subsequently joined Hood. On the night of the 5th, General Schofield, with the advance of the 23d corps, reached Johnsonville, but finding the enemy gone, was ordered to Pulaski, and was put in command of all the troopers there, with instruction to watch the movements of Hood and retard his advance, but not to risk a general engagement until the arrival of General A. J. Smith's command from Missouri, and until General Wilson could get his cavalry remounted.
On the 19th, General Hood continued his advance. General Thomas, retarding him as much as possible, fell back towards Nashville for the purpose of concentrating his command and gaining time for the arrival of reinforcements. The enemy coming up with our main force, commanded by General Schofield, at Franklin, on the 30th, assaulted our works repeatedly during the afternoon until late at night, but were in every instance repulsed. His loss in this battle was one thousand seven hundred and fifty killed, seven hundred and two prisoners, and three thousand eight hundred wounded. Among his losses were six general officers killed, six wounded, and one captured. Our entire loss was two thousand three hundred. This was the first serious opposition the enemy met with, and I am satisfied was the fatal blow to all his expectations. During the night, General Schofield fell back towards Nashville. This left the field to the enemy--not lost by battle, but voluntarily abandoned--so that General Thomas's whole force might be brought together. The enemy followed up and commenced the establishment of his line in front of Nashville on the 2d of December.
As soon as it was ascertained that Hood was crossing the Tennessee River, and that Price was going out of Missouri, General Rosecrans was ordered to send to General Thomas the troops of General A. J. Smith's command, and such other troops as he could spare. The advance of this reinforcement reached Nashville on the 30th of November.
On the morning of the 15th December, General Thomas attacked Hood in position, and, in a battle lasting two days, defeated and drove him from the field in the utmost confusion, leaving in our hand most of his artillery and many thousand prisoners, including four general officers.
Before the battle of Nashville I grew very impatient over, as it appeared to me, the unnecessary delay. This impatience was increased upon learning that the enemy had sent a force of cavalry across the Cumberland into Kentucky. I feared Hood would cross his whole army and give us great trouble there.
After urging upon General Thomas the necessity of immediately assuming the offensive, I started West to superintend matters there in person. Reaching Washington City, I received General Thomas's dispatch announcing his attack upon the enemy, and the result as far as the battle had progressed. I was delighted.
