For all these reasons the tenure of Mobile became a matter of serious consequence to the enemy; and, as Farragut had from the first foreseen, they made active use of the respite afforded them by the unfortunate obstinacy of the Navy Department in refusing him permission to attack after New Orleans fell. The enterprise then was by no means as difficult as the passage of the Mississippi forts just effected; and once captured, the holding of the harbor would require only the small number of troops necessary to garrison the powerful masonry fort which commanded the main ship channel, supported by a naval force much less numerous than that required to blockade outside. The undertaking was therefore not open to the objection of unduly exposing the troops and ships placed in unfortified or poorly fortified harbors, which received such a sad illustration at Galveston; but it was dropped, owing, first, to the preoccupation of the Government with its expectations of immediately reducing the Mississippi, and afterward to the fear of losing ships which at that time could not be replaced. Hesitation to risk their ships and to take decisive action when seasonable opportunity offers, is the penalty paid by nations which practise undue economy in their preparations for war. When at last it became urgent to capture Mobile before the powerful ironclad then building was completed, the preparations of the defense were so far advanced that ironclad vessels were needed for the attack; and before these could be, or at least before they were, supplied, the Tennessee, which by rapid action might have been forestalled like the similar vessel at New Orleans, was ready for battle. Had she been used with greater wisdom by those who directed her movements, she might have added very seriously to the embarrassment of the United States admiral.
When Farragut, after an absence of nearly six months, returned to his station in January, 1864, it was with the expectation of a speedy attack upon Mobile. On his way to New Orleans he stopped off the bar, and on the 20th of January made a reconnaissance with a couple of gunboats, approaching to a little more than three miles from the forts commanding the entrance. He then reported to the department that he was satisfied that, if he had one ironclad, he could destroy the whole of the enemy's force in the bay, and then reduce the forts at leisure with the co-operation of about five thousand troops. "But without ironclads," he added, "we should not be able to fight the enemy's vessels of that class with much prospect of success, as the latter would lie on the flats, where our ships could not get at them. By reference to the chart you will see how small a space there is for the ships to manœuvre. Wooden vessels can do nothing with the ironclads, unless by getting within one or two hundred yards, so as to ram them or pour in a broadside." He repeats the information given by a refugee, that the ironclad Nashville would not be ready before March, and that the Confederate admiral announced that when she was he would raise the blockade. "It is depressing," he adds, "to see how easily false reports circulate, and in what a state of alarm the community is kept by the most absurd rumors. If the Department could get one or two ironclads here, it would put an end to this state of things and restore confidence to the people of the ports now in our possession. I feel no apprehension about Buchanan's raising the blockade; but, with such a force as he has in the bay, it would be unwise to take in our wooden vessels without the means of fighting the enemy on an equal footing." Having made this reconnaissance, he went on to New Orleans, arriving there January 22d.
It appears, therefore, that, regarded as a naval question, Farragut considered the time had gone by for an attempt to run the forts of Mobile Bay, and that it would not return until some ironclads were furnished him by the Department. The capture of the forts he at no time expected, except by the same means as he had looked to for the reduction of those in the Mississippi—that is, by a combined military and naval operation. In both cases the navy was to plant itself across the enemy's communications, which it could do by running the gantlet of his guns. It then remained for the land forces either to complete the investment and await their fall by the slow process of famine, or to proceed with a regular siege covered by the fleet. Without the protection of the ships in the bay, the army would be continually harassed by the light gunboats of the enemy, and very possibly exposed to attack by superior force. Without the troops, the presence of the ships inside would be powerless to compel the surrender of the works, or to prevent their receiving some supplies. But in the two years that had very nearly elapsed since Farragut, if permitted his own wish, would have attacked, the strengthening of the works and the introduction of the ironclads had materially altered the question. He was, it is true, misinformed as to the readiness of the latter. The vessels that were dignified by that name when he first returned to his station, took no part in the defense, either of the bay or, later, of the city. He was deceived, probably, from the fact that the Confederates themselves were deceived, with the exception of a few who had more intimate knowledge of their real value; and consequently the reports that were brought off agreed in giving them a character which they did not deserve.
An attack upon Mobile had been a cherished project with General Grant after the fall of Vicksburg. It was to that—and not to the unfortunate Red River expedition of 1864—that he would have devoted Banks's army in the Southwest; moving it, of course, in concert with, so as to support and be supported by, the other great operations which took place that year—Sherman's advance upon Atlanta and his own against Richmond. It was to Mobile, and not to Savannah, that he first looked as the point toward which Sherman would act after the capture of Atlanta; the line from Atlanta to Mobile would be that along which, by the control of the intervening railroad systems, the Confederacy would again be cleft in twain, as by the subjugation of the Mississippi. For this reason chiefly he had, while still only commander of the Army of the Tennessee, and before he succeeded to the lieutenant-generalship and the command of all the armies, strenuously opposed the Red River expedition; which he looked upon as an ex-centric movement, tending rather to keep alive the war across the Mississippi, which would fade if left alone, and likely to result in the troops engaged not getting back in time or in condition to act against Mobile.
As Grant feared, so it happened. The expedition being already organized and on the point of starting when he became commander-in-chief, he allowed it to proceed; but it ended in disaster, and was the cause of forty thousand good troops being unavailable for the decisive operations which began two months later. Not until the end of July could a force be spared even for the minor task of reducing the Mobile forts; and until then Farragut had to wait in order to attack to any purpose. By the time the army in the Southwest, in the command of which General Canby relieved Banks on the 20th of May, was again ready to move, Sherman had taken Atlanta, Hood had fallen upon his communications with Chattanooga, and the famous march to the sea had been determined. Farragut's battle in Mobile Bay therefore did not prove to be, as Grant had hoped, and as his passage of the Mississippi forts had been, a step in a series of grand military operations, by which the United States forces should gain control of a line vital to the Confederacy, and again divide it into two fragments. It remained an isolated achievement, though one of great importance, converting Mobile from a maritime to an inland city, putting a stop to all serious blockade-running in the Gulf, and crushing finally the enemy's ill-founded hopes of an offensive movement by ironclads there equipped.
