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.
On the 6th of December, the following instructions were given:
"CITY POINT, VIRGINIA, December 6, 1864.
"GENERAL: The first object of the expedition under General Weitzel is to close to the enemy the port of Wilmington. If successful in this, the second will be to capture Wilmington itself. There are reasonable grounds to hope for success, if advantage can be taken of the absence of the greater part of the enemy's forces now looking after Sherman in Georgia. The directions you have given for the numbers and equipment of the expedition are all right, except in the unimportant matter of where they embark and the amount of intrenching tools to be taken. The object of the expedition will be gained by effecting a landing on the main land between Cape Fear River and the Atlantic, north of the north entrance to the river. Should such landing be effected while the enemy still holds Fort Fisher and the batteries guarding the entrance to the river, then the troops should intrench themselves, and, by co-operating with the navy, effect the reduction and capture of those places. These in our hands, the navy could enter the harbor, and the port of Wilmington would be sealed. Should Fort Fisher and the point of land on which it is built fall into the hands of our troops immediately on landing, then it will be worth the attempt to capture Wilmington by a forced march and surprise. If time is consumed in gaining the first object of the expedition, the second will become a matter of after consideration.
"The details for execution are intrusted to you and the officer immediately in command of the troops.
"Should the troops under General Weitzel fail to effect a landing at or near Fort Fisher, they will be returned to the armies operating against Richmond without delay.
"U. S. GRANT, Lieutenant-General.
"MAJOR-GENERAL B. F. BUTLER."

"MAJOR-GENERAL B. F. BUTLER."
General Butler commanding the army from which the troops were taken for this enterprise, and the territory within which they were to operate, military courtesy required that all orders and instructions should go through him. They were so sent, but General Weitzel has since officially informed me that he never received the foregoing instructions, nor was he aware of their existence, until he read General Butler's published official report of the Fort Fisher failure, with my indorsement and papers accompanying it. I had no idea of General Butler's accompanying the expedition until the evening before it got off from Bermuda Hundred, and then did not dream but that General Weitzel had received all the instructions, and would be in command. I rather formed the idea that General Butler was actuated by a desire to witness the effect of the explosion of the powder-boat. The expedition was detained several days at Hampton Roads, awaiting the loading of the powder-boat.
The importance of getting the Wilmington expedition off without any delay, with or without the powder-boat, had been urged upon General Butler, and he advised to so notify Admiral Porter.
The expedition finally got off on the 13th of December, and arrived at the place of rendezvous, off New Inlet, near Fort Fisher, on the evening of the 15th. Admiral Porter arrived on the evening of the 18th, having put in at Beaufort to get ammunition for the monitors. The sea becoming rough, making it difficult to land troops, and the supply of water and coal being about exhausted, the transport fleet put back to Beaufort to replenish; this, with the state of the weather, delayed the return to the place of rendezvous until the 24th. The powder-boat was exploded on the morning of the 24th, before the return of General Butler from Beaufort; but it would seem, from the notice taken of it in the Southern newspapers, that the enemy were never enlightened as to the object of the explosion until they were informed by the Northern press.
