Holly Springs I selected for my depot of supplies and munitions of war, all of which at that time came by rail from Columbus, Kentucky, except the few stores collected about La Grange and Grand Junction. This was a long line (increasing in length as we moved south) to maintain in an enemy's country. On the 15th of November, while I was still at Holly Springs, I sent word to Sherman to meet me at Columbus. We were but forty-seven miles apart, yet the most expeditious way for us to meet was for me to take the rail to Columbus and Sherman a steamer for the same place. At that meeting, besides talking over my general plans I gave him his orders to join me with two divisions and to march them down the Mississippi Central railroad if he could. Sherman, who was always prompt, was up by the 29th to Cottage Hill, ten miles north of Oxford. He brought three divisions with him, leaving a garrison of only four regiments of infantry, a couple of pieces of artillery and a small detachment of cavalry. Further reinforcements he knew were on their way from the north to Memphis. About this time General Halleck ordered troops from Helena, Arkansas (territory west of the Mississippi was not under my command then) to cut the road in Pemberton's rear. The expedition was under Generals Hovey and C. C. Washburn and was successful so far as reaching the railroad was concerned, but the damage done was very slight and was soon repaired.
The Tallahatchie, which confronted me, was very high, the railroad bridge destroyed and Pemberton strongly fortified on the south side. A crossing would have been impossible in the presence of an enemy. I sent the cavalry higher up the stream and they secured a crossing. This caused the enemy to evacuate their position, which was possibly accelerated by the expedition of Hovey and Washburn. The enemy was followed as far south as Oxford by the main body of troops, and some seventeen miles farther by McPherson's command. Here the pursuit was halted to repair the railroad from the Tallahatchie northward, in order to bring up supplies. The piles on which the railroad bridge rested had been left standing. The work of constructing a roadway for the troops was but a short matter, and, later, rails were laid for cars.
During the delay at Oxford in repairing railroads I learned that an expedition down the Mississippi now was inevitable and, desiring to have a competent commander in charge, I ordered Sherman on the 8th of December back to Memphis to take charge. The following were his orders:
Headquarters 13th Army Corps,
Department of the Tennessee.
OXFORD, MISSISSIPPI, December 8,1862.MAJOR-GENERAL W. T. SHERMAN,
Commanding Right Wing:You will proceed, with as little delay as possible, to Memphis, Tennessee, taking with you one division of your present command. On your arrival at Memphis you will assume command of all the troops there, and that portion of General Curtis's forces at present east of the Mississippi River, and organize them into brigades and divisions in your own army. As soon as possible move with them down the river to the vicinity of Vicksburg, and with the co-operation of the gunboat fleet under command of Flag-officer Porter proceed to the reduction of that place in such a manner as circumstances, and your own judgment, may dictate.
The amount of rations, forage, land transportation, etc., necessary to take, will be left entirely with yourself. The Quartermaster at St. Louis will be instructed to send you transportation for 30,000 men; should you still find yourself deficient, your quartermaster will be authorized to make up the deficiency from such transports as may come into the port of Memphis.
On arriving in Memphis, put yourself in communication with Admiral Porter, and arrange with him for his co-operation.
Inform me at the earliest practicable day of the time when you will embark, and such plans as may then be matured. I will hold the forces here in readiness to co-operate with you in such manner as the movements of the enemy may make necessary.
Leave the District of Memphis in the command of an efficient officer, and with a garrison of four regiments of infantry, the siege guns, and whatever cavalry may be there.
U. S. GRANT,
Major-General.
This idea had presented itself to my mind earlier, for on the 3d of December I asked Halleck if it would not be well to hold the enemy south of the Yallabusha and move a force from Helena and Memphis on Vicksburg. On the 5th again I suggested, from Oxford, to Halleck that if the Helena troops were at my command I though it would be possible to take them and the Memphis forces south of the mouth of the Yazoo River, and thus secure Vicksburg and the State of Mississippi. Halleck on the same day, the 5th of December, directed me not to attempt to hold the country south of the Tallahatchie, but to collect 25,000 troops at Memphis by the 20th for the Vicksburg expedition. I sent Sherman with two divisions at once, informed the general-in-chief of the fact, and asked whether I should command the expedition down the river myself or send Sherman. I was authorized to do as I though best for the accomplishment of the great object in view. I sent Sherman and so informed General Halleck.
As stated, my action in sending Sherman back was expedited by a desire to get him in command of the forces separated from my direct supervision. I feared that delay might bring McClernand, who was his senior and who had authority from the President and Secretary of War to exercise that particular command,—and independently. I doubted McClernand's fitness; and I had good reason to believe that in forestalling him I was by no means giving offence to those whose authority to command was above both him and me.
Neither my orders to General Sherman, nor the correspondence between us or between General Halleck and myself, contemplated at the time my going further south than the Yallabusha. Pemberton's force in my front was the main part of the garrison of Vicksburg, as the force with me was the defence of the territory held by us in West Tennessee and Kentucky. I hoped to hold Pemberton in my front while Sherman should get in his rear and into Vicksburg. The further north the enemy could be held the better.
It was understood, however, between General Sherman and myself that our movements were to be co-operative; if Pemberton could not be held away from Vicksburg I was to follow him; but at that time it was not expected to abandon the railroad north of the Yallabusha. With that point as a secondary base of supplies, the possibility of moving down the Yazoo until communications could be opened with the Mississippi was contemplated.
It was my intention, and so understood by Sherman and his command, that if the enemy should fall back I would follow him even to the gates of Vicksburg. I intended in such an event to hold the road to Grenada on the Yallabusha and cut loose from there, expecting to establish a new base of supplies on the Yazoo, or at Vicksburg itself, with Grenada to fall back upon in case of failure. It should be remembered that at the time I speak of it had not been demonstrated that an army could operate in an enemy's territory depending upon the country for supplies. A halt was called at Oxford with the advance seventeen miles south of there, to bring up the road to the latter point and to bring supplies of food, forage and munitions to the front.
On the 18th of December I received orders from Washington to divide my command into four army corps, with General McClernand to command one of them and to be assigned to that part of the army which was to operate down the Mississippi. This interfered with my plans, but probably resulted in my ultimately taking the command in person. McClernand was at that time in Springfield, Illinois. The order was obeyed without any delay. Dispatches were sent to him the same day in conformity.
