For some time it had been known in Federal military and naval circles that a powerful ironclad similar to the famous Monitor of Eastern waters was being rushed to completion up the Yazoo. The new vessel was the Arkansas. On July 15th, she steamed through the Union fleet, bravely exchanging broadsides, and lodged safely under the guns of Vicksburg. That evening the Federal boats in turn ran past the doughty Arkansas, but failed to destroy her.
The month of July had not been favorable to the Federal hopes. Farragut had returned to New Orleans. General Williams had gone with him as far as Baton Rouge. Davis now went with his fleet back to Helena. Halleck was succeeded by Grant. Vicksburg entered upon a period of quiet.
But this condition was temporary. The city’s experience of blood and fire had only begun. During the summer and autumn of 1862, the one thought uppermost in the mind of General Grant was how to gain possession of the stronghold. He was already becoming known for his bull-dog tenacity. In the autumn, two important changes took place, but one day apart. On October 14th, General John C. Pemberton succeeded Van Dorn in command of the defenses of Vicksburg, and on the next day David D. Porter succeeded Davis as commander of the Federal fleet on the upper Mississippi.
So arduous was the task of taking Vicksburg that the wits of General Grant, and those of his chief adviser, General W. T. Sherman, were put to the test in the last degree to accomplish the end. Grant knew that the capture of this fortified city was of great importance to the Federal cause, and that it would ever be looked upon as one of the chief acts in the drama of the Civil War.
The first plan attempted was to divide the army, Sherman taking part of it from Memphis and down the Mississippi on transports, while Grant should move southward along the line of the Mississippi Central Railroad to cooperate with Sherman, his movements to be governed by the efforts of the scattered Confederate forces in Mississippi to block him. But the whole plan was destined to failure, through the energies of General Van Dorn and others of the Confederate army near Grant’s line of communication.
The authorities at Washington preferred the river move upon Vicksburg, as the navy could keep the line of communication open. The stronghold now stood within a strong line of defense extending from Haynes’ Bluff on the Yazoo to Grand Gulf on the Mississippi, thirty miles below Vicksburg. To prepare for Sherman’s attack across the swamps of the Yazoo, Admiral Porter made several expeditions up that tortuous stream to silence batteries and remove torpedoes. In one of these he lost one of the Eads ironclads, the Cairo, blown up by a torpedo, and in another the brave Commander Gwin, one of the heroes of Shiloh, was mortally wounded.
Sherman, with an army of thirty-two thousand men, left Memphis on December 20th, and landed a few days later some miles north of Vicksburg on the banks of the Yazoo. On the 29th he made a daring attack in three columns on the Confederate lines of defense at Chickasaw Bayou and suffered a decisive repulse. His loss was nearly two thousand men; the Confederate loss was scarcely two hundred.
Two hundred feet above the bayou, beyond where the Federals were approaching, towered the Chickasaw Bluffs, to which Pemberton hastened troops from Vicksburg as soon as he learned Sherman’s object. At the base of the bluff, and stretching away to the north and west were swamps and forests intersected by deep sloughs, overhung with dense tangles of vines and cane-brakes. Federal valor vied with Confederate pluck in this fight among the marshes and fever-infested jungle-land.
One of Sherman’s storming parties, under General G. W. Morgan, came upon a broad and deep enlargement of the bayou, McNutt Lake, which interposed between it and the Confederates in the rifle-pits on the slopes and crest of the bluff. In the darkness of the night of December 28th, the Federal pontoniers labored to construct a passage-way across the lake. When morning dawned the weary pontoniers were chagrined to discover their well-built structure spanning a slough leading in another direction than toward the base of the bluff. The bridge was quickly taken up, and the Federals recommenced their labors, this time in daylight and within sight and range of the Southern regiments on the hill. The men in blue worked desperately to complete the span before driven away by the foe’s cannon; but the fire increased with every minute, and the Federals finally withdrew.
Another storming party attempted to assail the Confederates from across a sandbar of the bayou, but was halted at the sight and prospect of overcoming a fifteen-foot bank on the farther side. The crumbling bank was surmounted with a levee three feet high; the steep sides of the barrier had crumbled away, leaving an overhanging shelf, two feet wide. Two companies of the Sixth Missouri regiment volunteered to cross the two hundred yards of exposed passage, and to cut a roadway through the rotten bank to allow their comrades a free path to the bluff beyond. To add to the peril of the crossing, the sandbar was strewn with tangles of undergrowth and fallen trees, and the Confederate shells and bullets were raining upon the ground. Still, the gallant troops began their dash. From the very start, a line of wounded and dead Missourians marked the passage of the volunteers. The survivors reached the bank and desperately sought to dig the roadway. From the shrubbery on the bank suddenly appeared Confederate sharpshooters who poured their fire into the laboring soldiers; the flame of the discharging muskets burned the clothing of the Federals because the hostile forces were so close. Human endurance could not stand before this carnage, and the brave Missourians fled from the inferno. Sherman now found the northern pathway to Vicksburg impassable, and withdrew his men to the broad Mississippi.
