On the 2d of May, therefore, Farragut sent Craven with the Brooklyn and six other vessels of the fleet up the river. On the 8th, as early as the river transports could be secured, Butler sent Williams with the 4th Wisconsin and the 6th Michigan regiments, and two sections of Everett's 6th Massachusetts battery, to follow and accompany the fleet. The next day Williams landed his force at Bonnet Carré, on the east bank of the river, about thirty-five miles above the town. After wading about five miles through a swamp, where the water and mud were about three feet deep, the troops halted at night at Frenier, a station of the Jackson railway, situated on the shore of Lake Pontchartrain, about ten miles above Kenner. A detachment of the 4th Wisconsin, under Major Boardman, was sent to Pass Manchac. The Confederates made a slight but ineffective resistance with artillery, resulting in trivial losses on either side. The bridges at Pass Manchac and Frenier being then destroyed, on the following morning, the 10th, the troops marched back the weary ten miles along the uneven trestle-work of the railway from Frenier to Kenner and there took transport. After their long confinement on shipboard, with scant rations, without exercise or even freedom of movement, the excessive heat of the day caused the troops to suffer severely. The embarkation completed, the transports, under convoy of the navy, set out for Baton Rouge. There on the morning of the 12th of May the troops landed, the capitol was occupied by the 4th Wisconsin, and the national colors were hoisted over the building. The troops then re-embarked for Vicksburg.
Natchez surrendered on the 12th of May to Commander S. Phillips Lee, of the Oneida, the advance of Farragut's fleet. On the 18th of May the Oneida and her consorts arrived off Vicksburg, and the same day Williams and Lee summoned "the authorities" to surrender the town and "its defences to the lawful authority of the United States." To this Brigadier-General Martin L. Smith, commander of the defences, promptly replied: "Having been ordered here to hold these defences, my intention is to do so as long as it is in my power."
On the 19th the transports stopped for wood at Warrenton, about ten miles below Vicksburg, and here a detachment of the 4th Wisconsin, sent to guard the working party, became involved in a skirmish with the Confederates, in which Sergeant-Major N. H. Chittenden and Private C. E. Perry, of A Company, suffered the first wounds received in battle by the troops of the United States in the Department of the Gulf. The Confederates were easily repulsed, with small loss.
Almost at the instant when Farragut was decided to run the gauntlet of the forts, Beauregard had begun to fortify Vicksburg. Up to this time he had trusted the defence of the river above New Orleans to Fort Pillow, Helena, and Memphis.
When Smith took command at Vicksburg on the 12th of May, in accordance with the orders of Lovell, the department commander, three of the ten batteries laid out for the defence of the position had been nearly completed and a fourth had been begun. These batteries were intended for forty-eight guns from field rifles to 10-inch columbiads. The garrison was to be 3,000 strong, but at this time the only troops present were parts of two Louisiana regiments. When the fleet arrived, on the 18th, six of the ten batteries had been completed, and two days later twenty-three heavy guns were in place and the defenders numbered more than 2,600.
The guns of the navy could not be elevated sufficiently for their projectiles to reach the Confederate batteries on the bluff, and the entire land-force, under Williams, was less than 1,100 effectives. Even had it been possible by a sudden attack to surprise and overcome the garrison and seize the bluffs, the whole available force of the Department of the Gulf would have been insufficient to hold the position for a week, as things then stood.
The truth is that the northern column with which, following their orders, Butler and Farragut were now trying to co-operate had ceased to exist; Jackson meant Beauregard's rear; and, as for any co-operation between Halleck and Williams, Beauregard stood solidly between them. On the 17th of April, the day before Porter's mortars first opened upon Forts Jackson and St. Philip, the whole land force of this northern column, under Pope, at that moment preparing for the attack on Fort Pillow, had been withdrawn by imperative orders from Halleck, and, on the very evening before the attack on Fort Pillow was to have been made, had gone to swell the great army assembled under Halleck at Corinth; but as yet neither Butler nor Farragut knew anything of all this. Save by the tedious roundabout of Washington, New York, the Atlantic, and the Gulf, there was at this time no regular or trustworthy means of communication between the forces descending the Mississippi and those that had just achieved the conquest of New Orleans and were now ascending the river to co-operate with the northern column. Thus it was that a single word, daubed in a rude scrawl upon the walls of the custom-house, meeting the eyes of Paine's men after they had made a way into the building with their axes, gave to Butler the first intelligence of the desperate battle of the 6th and 7th of April, on which the fate of the whole Union campaign in the West had been staked, if not imperilled, and which in its result was destined to change materially the whole course of operations in the Gulf Department. That word was Shiloh.
By the 26th of May the Oneida had been joined by the rest of the fleet, under the personal command of the restless and energetic flag-officer. On the afternoon of this day the fleet opened fire. The Confederates replied sparingly, as much to economize their ammunition and to keep the men fresh, as to avoid giving the Union commanders information regarding the range and effect of their fire.
The river was now falling. The Hartford in coming up had already grounded hard, and so remained helpless for fifty hours, and had only been got off by incredible exertions. Provisions of all kinds were running very low. On the 25th of May, after a thorough reconnoissance, Farragut and Williams decided to give up the attempt on Vicksburg as evidently impracticable. Farragut left Palmer with the Iroquois and six gunboats to blockade the river and to amuse the garrison at Vicksburg by an occasional bombardment in order to prevent Smith from sending reinforcements to Corinth.
While Williams was descending the river on the 26th, the transports were fired into by the Confederate battery on the bluff at Grand Gulf, sixty miles below Vicksburg. About sixty rounds were fired in all, many of which passed completely through the transport Laurel Hill, bearing the 4th Wisconsin, part of the 6th Michigan, and the 6th Massachusetts battery. One private of the 6th Michigan was killed and Captain Chauncey J. Bassett, of the same regiment, wounded. The Ceres, bearing the remainder of the 6th Michigan and the 6th Massachusetts battery, was following the Laurel Hill and was similarly treated. After a stern chase of about twenty miles, the convoy was overhauled, and the gunboat Kineo, returning, shelled the town and caused the withdrawal of the battery. During the evening Williams sent four companies of the 4th Wisconsin, under Major Boardman, to overtake the enemy's battery and break up the camp, about one mile and a half in the rear of the town. Boardman came upon the Confederates as they were retiring, and shots were exchanged. The casualties were few, but Lieutenant George DeKay, a gallant and attractive young officer, serving as aide-de-camp to General Williams, received a mortal wound.
