For more than a year the possession of Vicksburg had been the ultimate object of the military and naval operations of the principal forces of the United States in the west, before that object was attained. After the unsuccessful naval and military operations in July, 1862, repeated expeditions had been set on foot, at immense expense to the Government, accompanied with great labor and privation on the part of the patriots engaged in the enterprises, only to be met in turn with disaster and reverse. These operations were under the direction of Major-General Grant, commander-in-chief of the army of West Tennessee, and may take their date about December 1, 1862, at which time the principal forces of General Grant were at La Grange, three miles east of Grand Junction, on the Cairo and New Orleans railroad. General Grant was placed in command of the Department of Tennessee, embracing all the country west of the Tennessee river, and on both shores of the Mississippi river, from Corinth to Louisiana. He was in command of the Thirteenth Army Corps, and his troops fought the famous battles of Iuka and Corinth, although General Grant did not command in person, being at Jackson, Tennessee, his headquarters. In December, 1862, he removed his headquarters to Holly Springs; and on the 22d of that month, his forces having greatly increased, he divided them into four corps, viz.: the Thirteenth, Fifteenth, Sixteenth, and Seventeenth Corps of the United States Army.
The first expedition, under General Grant, was started in December, 1862. The plan of General Grant was—that General Sherman should take command of the forces in Memphis in Tennessee, and Helena in Arkansas, and descend the river on transports with the gunboat fleet, and make an attack on Vicksburg by the 29th of December; and that General McClernand should take the forces at Cairo and move down to Vicksburg, thus reinforcing General Sherman soon after his attack on the town. Meanwhile, General Grant was to advance rapidly upon the Confederate troops in Mississippi north and east of Vicksburg, which formed the main body of their army, and keep them fully employed, and, if they retreated to Vicksburg, arrive there with them, ready to cooperate with General Sherman.
The Confederate force, now under the command of General Pemberton, retired to the river, and finally fell back beyond Granada. Meanwhile General Grant advanced to Oxford, and on the 20th of December an attack was suddenly made in his rear, by a Confederate force under General Van Dorn, on the garrison under Colonel Murphy at Holly Springs, which surrendered. The prisoners were paroled and the supplies collected there for General Grant’s army were destroyed; also a large quantity of cotton which had been purchased of the people in the vicinity.
The surrender of Holly Springs was a severe blow to General Grant, and the officers in command were severely censured by him. Colonel Murphy, the commander, allowed himself to be taken by surprise, and surrendered all of his command, and an immense quantity of supplies, which had been gathered there for the use of the advancing army.
While General Grant was moving his columns toward the objective point, the enemy were by no means idle. On the same day on which Colonel Murphy surrendered Holly Springs, an attack was made on Davis’s Mills, a post a little farther north, which was bravely repulsed. On the next day, Humboldt was captured, and an attack made on Trenton, while several important stations on the railroad were, in turn, visited by the Confederate raiders, who demolished the equipments of the roads, cut the telegraph lines, and inflicted serious injury, by destroying the communications of General Grant’s army, which compelled him to make a retrograde movement, or fall back on Holly Springs. This left General Pemberton at liberty to concentrate his forces at Vicksburgh against General Sherman, who was then advancing on that place in accordance with General Grant’s plan, while the cooperating forces were removed so far from the scene of action, that there was no hope of their being able to afford any assistance, either by participation or by the diversion of any portion of the enemy’s forces.
Meanwhile General W. T. Sherman, who had been stationed at Memphis, embarked with one division on the 20th of December, and dropped down to Friar’s Point, the place of rendezvous, where he was joined by Admiral Porter with his flagship and two consorts.
The arrangements were completed by the military and naval commanders during the next forenoon, the 22d, and the fleet got under way, and moved down just below the mouth of White river, where it came to, at sunset. On the next day it descended to Gaines’s Landing, and at two P. M. came to anchor, to await the arrival of the transports in the rear, and also a division of troops from Memphis. Half of the town of Gaines’s Landing was destroyed by fire while the army was there. Similar destruction had also been made at Friar’s Point. These acts led to stringent measures on the part of General Sherman.
On the morning of the 25th, the fleet arrived at the mouth of the Yazoo river. The fleet consisted of more than sixty transports, with a number of iron-clad and other gunboats, and several mortar boats. The Yazoo is a deep, narrow, and sluggish stream, formed by the Tallahatchie and Yallobusha rivers, which unite in Carroll county, Mississippi. It runs through an alluvial plain of extreme fertility, about two hundred and ninety miles, and empties into the Mississippi river twelve miles above Vicksburg.
On the 26th, the expedition, under convoy of the gunboats, moved up the Yazoo, and the troops were landed at various points from the junction of Old River with the Yazoo to Johnson’s Farm, a distance of about three miles, without opposition. The distance from Vicksburg was about eight miles. A strong position, known as Haines’s Bluff, some distance above on the river, was held by the Confederate forces, and in the mean while attacked by the gunboats De Kalb, Cincinnati, Louisville, Benton and Lexington. It was the plan of General Sherman to attack Vicksburg in the rear. For this purpose he was engaged, on the 28th, in getting his forces in position.
Vicksburg is situated upon a high bluff, rising nearly a hundred feet above the water. This bluff faces very nearly to the west. The Mississippi in front of Vicksburg runs in a southwesterly course. These bluffs are on its eastern bank, and run off from a point five miles below the city directly inland from the head of the bend in the Mississippi until they strike the Yazoo river, nine miles northeast of Vicksburg in a straight line, and twenty-three miles from the Mississippi by the course of the Yazoo river.
