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. All fears and apprehensions were dispelled. I am not yet satisfied but that General Thomas, immediately upon the appearance of Hood before Nashville, and before he had time to fortify, should have moved out with his whole force and given him battle, instead of waiting to remount his cavalry, which delayed him until the inclemency of the weather made it impracticable to attack earlier than he did. But his final defeat of Hood was so complete, that it will be accepted as a vindication of that distinguished officer's judgment.
After Hood's defeat at Nashville he retreated, closely pursued by cavalry and infantry, to the Tennessee River, being forced to abandon many pieces of artillery and most of his transportation. On the 28th of December our advanced forces ascertained that he had made good his escape to the south side of the river.
About this time, the rains having set in heavily in Tennessee and North Alabama, making it difficult to move army transportation and artillery, General Thomas stopped the pursuit by his main force at the Tennessee River. A small force of cavalry, under Colonel W. J. Palmer, 15th Pennsylvania Volunteers, continued to follow Hood for some distance, capturing considerable transportation and all the enemy's pontoon-bridge. The details of these operations will be found clearly set forth in General Thomas's report.
A cavalry expedition, under Brevet Major-General Grierson, started from Memphis on the 21st of December. On the 25th he surprised and captured Forrest's dismounted camp at Verona, Mississippi, on the Mobile and Ohio Railroad, destroyed the railroad, sixteen cars loaded with wagons and pontoons for Hood's army, four thousand new English carbines, and large amounts of public stores. On the morning of the 28th he attacked and captured a force of the enemy at Egypt, and destroyed a train of fourteen cars; thence turning to the south-west, he struck the Mississippi Central Railroad at Winona, destroyed the factories and large amounts of stores at Bankston, and the machine-shops and public property at Grenada, arriving at Vicksburg January 5th.
During the operations in Middle Tennessee, the enemy, with a force under General Breckinridge, entered East Tennessee. On the 13th of November he attacked General Gillem, near Morristown, capturing his artillery and several hundred prisoners. Gillem, with what was left of his command, retreated to Knoxville. Following up his success, Breckinridge moved to near Knoxville, but withdrew on the 18th, followed by General Ammen. Under the directions of General Thomas, General Stoneman concentrated the commands of Generals Burbridge and Gillem near Bean's Station to operate against Breckinridge, and destroy or drive him into Virginia —destroy the salt-works at Saltville, and the railroad into Virginia as far as he could go without endangering his command. On the 12th of December he commenced his movement, capturing and dispersing the enemy's forces wherever he met them. On the 16th he struck the enemy, under Vaughn, at Marion, completely routing and pursuing him to Wytheville, capturing all his artillery, trains, and one hundred and ninety-eight prisoners; and destroyed Wytheville, with its stores and supplies, and the extensive lead-works near there. Returning to Marion, he met a force under Breckinridge, consisting, among other troops, of the garrison of Saltville, that had started in pursuit. He at once made arrangements to attack it the next morning; but morning found Breckinridge gone. He then moved directly to Saltville, and destroyed the extensive salt-works at that place, a large amount of stores, and captured eight pieces of artillery. Having thus successfully executed his instructions, he returned General Burbridge to Lexington and General Gillem to Knoxville.
Wilmington, North Carolina, was the most important sea-coast port left to the enemy through which to get supplies from abroad, and send cotton and other products out by blockade-runners, besides being a place of great strategic value. The navy had been making strenuous exertions to seal the harbor of Wilmington, but with only partial effect. The nature of the outlet of Cape Fear River was such, that it required watching for so great a distance that, without possession of the land north of New Inlet, or Fort Fisher, it was impossible for the navy to entirely close the harbor against the entrance of blockade-runners.
To secure the possession of this land required the co-operation of a land force, which I agreed to furnish. Immediately commenced the assemblage in Hampton Roads, under Admiral D. D. Porter, of the most formidable armada ever collected for concentration upon one given point. This necessarily attracted the attention of the enemy, as well as that of the loyal North; and through the imprudence of the public press, and very likely of officers of both branches of service, the exact object of the expedition became a subject of common discussion in the newspapers both North and South. The enemy, thus warned, prepared to meet it. This caused a postponement of the expedition until the later part of November, when, being again called upon by Hon. G. V. Fox, Assistant Secretary of the Navy, I agreed to furnish the men required at once, and went myself, in company with Major-General Butler, to Hampton Roads, where we had a conference with Admiral Porter as to the force required and the time of starting. A force of six thousand five hundred men was regarded as sufficient. The time of starting was not definitely arranged, but it was thought all would be ready by the 6th of December, if not before. Learning, on the 30th of November, that Bragg had gone to Georgia, taking with him most of the forces about Wilmington, I deemed it of the utmost importance that the expedition should reach its destination before the return of Bragg, and directed General Butler to make all arrangements for the departure of Major-General Weitzel, who had been designated to command the land forces, so that the navy might not be detained one moment.
