Meanwhile Williams was hard at work on the canal. In addition to such details as could be furnished by the troops without wholly neglecting the absolutely necessary portions of their military duties, Williams had employed a force of about 1,200 negroes, rather poorly provided with tools. The work was not confined to excavation, but involved the cutting down of the large cottonwoods and the clearing away of the dense masses of willows that covered the low ground and matted the heavy soil with their tangled roots. By the 4th of July the excavation had reached a depth in the hard clay of nearly seven feet. The length of the canal was about one and a half miles. By the 11th of July the cut, originally intended to be four feet deep and five feet wide, with a profile of twenty square feet, had been excavated through this stiff clay to a depth of thirteen feet and a width of eighteen feet, presenting a profile of 234 feet. The river, which, up to this time, had been falling more rapidly than the utmost exertions had been able to sink the bottom of the canal, had now begun to fall more slowly, so that at last the grade was about eighteen inches below the river level. In a few hours the water was to have been let in. Suddenly the banks began to cave, and before any thing could be done to remedy this, the river, still falling, was once more below the bottom of the cut. Although with this scanty and overworked force he had already performed nearly twelve times the amount of labor originally contemplated, Williams does not seem to have been discouraged at this; his orders were to make the cut, and his purpose clearly was to make it, even if it should take, as he thought it would, the whole of the next three months. He set to work with vigor to collect laborers, wheelbarrows, shovels, axes, carts, and scrapers, and "to make a real canal," to use his own words, "to the depth of the greatest fall of the river at this point, say some thirty-five to forty feet." But this was not to be.
Until toward the end of June, the Polk and Livingston, the last vestiges of the Confederate navy on the Mississippi spared from the general wreck at Memphis, lay far up the Yazoo River, with a barrier above them, designed to cover the building of the ram Arkansas. This formidable craft was approaching completion at Yazoo City. The Ellets, uncle and nephew, with the Monarch and Lancaster, steamed up the Yazoo River to reconnoitre. The rams carried no armament whatever, but this the Confederate naval commander in the Yazoo did not know; so, unable to pass the barrier, he set fire to his three gunboats immediately on perceiving Ellet's approach. On the 14th of July, Flag-Officers Farragut and Davis sent the gunboats Carondelet and Tyler, and the ram Queen of the West, on a second expedition up the Yazoo to gain information of the Arkansas. This object was greatly facilitated by the fact that the Arkansas had at this very moment just got under way for the first time, and was coming down the Yazoo to gather information of the Federal fleet. The Arkansas, which had been constructed and was now commanded by Captain Isaac N. Brown, formerly of the United States Navy, was, for defensive purposes, probably the most effective of all the gunboats ever set afloat by the Confederacy upon the western waters. Her deck was covered by a single casemate protected by three inches of railroad iron, set aslant like a gable roof, and heavily backed up with timber and cotton bales. Her whole bow formed a powerful ram; the shield, flat on the top, was pierced for ten guns of heavy calibre, three in each broadside, two forward, and two aft. Had her means of propulsion proved equal to her power of attack and defence, it is doubtful if the whole Union navy on the Mississippi could have stood against her single-handed. The situation thus strangely recalls that presented by the Merrimac, or Virginia, in Hampton Roads before the opportune arrival of the Monitor. On board the Tyler was a detachment of twenty sharpshooters of the 4th Wisconsin regiment, under Captain J. W. Lynn, and on the Carondelet were twenty men of the 30th Massachusetts regiment, under Lieutenant E. A. Fiske. About six miles above the Yazoo the Union gunboats encountered the Arkansas. The unarmed ram Queen of the West promptly fled. After a hard fight the Carondelet was disabled and run ashore, and the Tyler was forced to retire, with the Arkansas in pursuit. The sharpshooters of the 4th Wisconsin suffered more severely than if they had been engaged in an ordinary pitched battle, Captain Lynn and six of his men being killed and six others wounded.
The Queen of the West, flying out of the mouth of the Yazoo under a full head of steam, gave to the fleet at anchor the first intimation, though perhaps a feeble one, of what was to follow. Not one vessel of either squadron had steam. The ram Bragg, which might have been expected to do something, did nothing. The Arkansas, so seriously injured by the guns of the Carondelet and Tyler that the steam pressure had gone from 120 pounds to the square inch down to 20 pounds, kept on her course, and proceeded to run the gauntlet of the Union fleet, giving and taking blows as she went. Battered, but safe, she soon lay under the guns of Vicksburg.
This decided the fate of the campaign, and extinguished in the breast of Farragut the last vestige of the ardent hope he had expressed to the government a few days earlier that he might soon have the pleasure of recording the combined attack of the army and navy, for which all so ardently longed. The river was falling; the canal was a failure. Of the officers and men of the army, two fifths, and of the effective force of the army nearly three fourths, were on the sick-list. There was no longer any thing to hope for or to wait on. The night that followed the exploit of the Arkansas saw Farragut's fleet descending the river and once more running the gauntlet of the batteries of Vicksburg. A flying attempt was made by each vessel in succession, but by all unsuccessfully, to destroy the offending Arkansas.
On the 24th of July, Williams, with his small force, under convoy of Farragut's fleet, sailed down the river. So ended the second attempt on Vicksburg, usually called the first, when remembered. Its sudden collapse gave the Confederates the river for another year.
CHAPTER III. BATON ROUGE.
On the 26th of July, the troops landed at Baton Rouge. In the five weeks that had elapsed since their departure their effective strength had been diminished, by privations, by severe labor, and by the effects of a deadly climate, from 3,200 to about 800. For more than three months, ever since their re-embarkation at Ship Island on the 10th of April, they had undergone hardships such as have seldom fallen to the lot of soldiers, in a campaign whose existence is scarcely known and whose name has been wellnigh forgotten; but their time for rest and recreation had not yet come.
No sooner did Van Dorn see the allied fleets of Davis and Farragut turning their backs on one another and steaming one to the north and the other to the south, than he determined to take the initiative. His preparations had been already made in anticipation of this event. He now ordered Breckinridge to hasten with his division to the attack of Baton Rouge, and even as the fleet got under way, the train bearing Breckinridge's troops was also in motion.
Breckinridge received his orders on the 26th, and arrived at Camp Moore by the railway on the 28th. At Jackson he had been told that he would receive rations sufficient for ten days, but he could get no more than half the quantity. Van Dorn had estimated the Union force to be met at Baton Rouge as about 5,000, and had calculated that Breckinridge would find himself strong enough to dislodge the Union army and drive it away. In fact, Van Dorn estimated Breckinridge's division, including 1,000 men under Brigadier-General Ruggles that were to meet him at Camp Moore, at 6,000 men. The Arkansas was to join in the attack, and she was justly considered a full offset to any naval force the Union commander would be likely to have stationed at Baton Rouge. Breckinridge left Vicksburg with less than 4,000. On the 30th of July he reports his total effective force, including Ruggles, at 3,600. The same day he marched on Baton Rouge, and on the 4th of August encamped at the crossing of the Comite, distant about ten miles from his objective. His morning report of that day shows but 3,000 effectives, according to the methods by which effective strength was commonly counted by the Confederates.
The distance from Camp Moore to Baton Rouge is about sixty miles, and the march had been thus retarded to await the co-operation of the Arkansas. This Breckinridge was finally assured he might expect at daylight on the morning of the 5th of August. The Arkansas had in fact left Vicksburg on the 3d.
