Between the city and the lower bay there were extensive flats, over which not even the fourteen feet of the Tennessee could be taken; and these in one part, called Dog River Bar, shoaled to as little as nine feet. To bring the Tennessee into action for the defense of the entrance and of the lower bay, it was necessary to carry her across these flats—an undertaking requiring both time and mechanical appliances, neither of which would be available if an enemy were inside to molest the operations. As the Tennessee was distinctly the most formidable element in the dangers Farragut had to encounter, and as the character of the soundings gave her a field of action peculiarly suited to utilize her especial powers, which consisted in the strength of her sides and the long range of her heavy rifled guns, it was particularly desirable to anticipate her crossing the upper bar by the fleet itself crossing the lower. That done, the Tennessee was reduced to impotence. It was not done, for two reasons. First, the Navy Department did not send the ironclads which Farragut demanded; and second, the army in the Southwest, having wasted its strength in a divergent operation, was unable to supply the force necessary to reduce Fort Morgan. That the delay was not productive of more serious consequences was due to the impatience or recklessness of the Confederate admiral, and to the energy with which Farragut seized the opportunity afforded by his mistake.

Six months passed before the moment for decisive action arrived. Though devoid of military interest, they were far from being months of idleness or enjoyment. The administrative duties of so large a command drew heavily upon the time and energies of the admiral, and, as has been said, they were not congenial to him. When the Tennessee crossed Dog River Bar, which she did on the 18th of May, Farragut felt that he must be on the spot, in case she attempted to execute her threat of coming out to break up the blockade; but up to that time he was moving actively from point to point of his command, between New Orleans on the one side, and Pensacola, now become his principal base, on the other. From time to time he was off Mobile, and for more than two months preceding the battle of the Bay he lay off the port in all the dreary monotony of blockade service. The clerical labor attaching to the large force and numerous interests entrusted to him was immense. Every mail brought him, of course, numerous communications from the Department. "I received your letter last evening," he writes to a member of his family, "but at the same time received so many from the Department that my eyes were used up before I came to yours, so that mine to you will be short and badly written." A very large part of this correspondence consisted of letters from United States consuls abroad, forwarded through the State Department, giving particulars of vessels fitting or loading for the Confederacy or to break the blockade. "Nearly all my clerical force is broken down," he writes on another occasion. "The fact is, I never saw so much writing; and yet Drayton, who does as much as any of them, says it is all necessary. So I tell them to go on. I do not mind signing my name. Although I write all my own letters, some one has to copy them. My fleet is so large now that it keeps us all at work the whole time."

But while he spoke thus lightly of his own share in these labors, the confinement, the necessary attention to and study of larger details, even while he intrusted the minor to others, and the unavoidable anxieties of a man who had so many important irons in the fire, and at the same time was approaching his sixty-fourth year, told upon him. To this he bore witness when, after the capture of the Mobile forts, the Department desired him to take command of the North Atlantic fleet, with a view to the reduction of Wilmington, North Carolina. "They must think I am made of iron," he wrote home. "I wrote the Secretary a long letter, telling him that my health was not such as to justify my going to a new station to commence new organizations; that I must have rest for my mind and exercise for my body; that I had been down here within two months of five years, out of six, and recently six months on constant blockade off this port, and my mind on the stretch all the time; and now to commence a blockade again on the Atlantic coast! Why, even the routine of duty for a fleet of eighty sail of vessels works us all to death; and but that I have the most industrious fleet-captain and secretary, it would never be half done. It is difficult to keep things straight." "I know," he writes on another occasion, "that few men could have gone through what I have in the last three years, and no one ever will know except yourself perhaps.... What the fight was to my poor brains, neither you nor any one else will ever be able to comprehend. Six months constantly watching day and night for an enemy; to know him to be as brave, as skilful, and as determined as myself; who was pledged to his Government and the South to drive me away and raise the blockade, and free the Mississippi from our rule. While I was equally pledged to my Government that I would capture or destroy the rebel."

Besides his labors and the official anxieties due to his individual command, he again, as in 1862, felt deeply the misfortunes with which the general campaign of 1864 opened, and especially in the Southwest. There was continually present to the minds of the leaders of the United States forces during the war the apprehension that the constancy of the people might fail; that doubtful issues might lead to a depression that would cause the abandonment of the contest, in which success was nevertheless assured to perseverance and vigor. Grant's memoirs bear continual testimony to the statesmanlike regard he had, in planning his greater military operations, to this important factor in the war, the vacillation under uncertainty of that popular support upon which success depended. The temperament of Farragut reflected readily the ups and downs of the struggle, and was saddened by the weaknesses and inconsistencies of his own side, which he keenly appreciated. "I am depressed," he writes, "by the bad news from every direction. The enemy seem to be bending their whole soul and body to the war and whipping us in every direction. What a disgrace that, with their slender means, they should, after three years, contend with us from one end of the country to the other!... I get right sick, every now and then, at the bad news." "The victory of the Kearsarge over the Alabama," on a more auspicious occasion, "raised me up. I would sooner have fought that fight than any ever fought on the ocean"; and his exultation was the greater that the first lieutenant of the Kearsarge had been with him in the same capacity when the Hartford passed the Mississippi forts.

But, while thus sensitive to the vicissitudes of his country's fortunes, he did not readily entertain the thought of being himself defeated. "As to being prepared for defeat," he wrote before New Orleans, "I certainly am not. Any man who is prepared for defeat would be half defeated before he commenced. I hope for success; shall do all in my power to secure it, and trust to God for the rest." And again: "The officers say I don't believe anything. I certainly believe very little that comes in the shape of reports. They keep everybody stirred up. I mean to be whipped or to whip my enemy, and not to be scared to death." "I hope for the best results," he wrote a week before forcing the passage into Mobile Bay, "as I am always hopeful; put my shoulder to the wheel with my best judgment, and trust to God for the rest"; or, in more homely language: "Everything has a weak spot, and the first thing I try to do is to find out where it is, and pitch into it with the biggest shell or shot that I have, and repeat the dose until it operates." "The Confederates at Fort Morgan are making great preparations to receive us. That concerns me but little"—words used not in a spirit of mere light-heartedness, but because it was a condition he had from the first accepted, and over which he hoped to triumph; for he continues, "I know they will do all in their power to destroy us, and we will reciprocate the compliment. I hope to give them a fair fight if once I get inside. I expect nothing from them but that they will try to blow me up if they can."

Amid such cares and in such a spirit were spent the six months of monotonous outside blockade preceding the great victory that crowned his active career. The only relief to its weariness was a bombardment of Fort Powell, undertaken by the light-draft steamers of the squadron from Mississippi Sound in February, to create a diversion in favor of Sherman's raid from Vicksburg upon Meridian, which was then in progress. The boats could not get nearer to the work than four thousand yards, and even then were aground; so that no very serious effect was produced. A greater and more painful excitement was aroused by the misfortunes of the Red River expedition in April and May. Begun on unsound military principles, but designed politically to assert against French intrigues the claim of the United States to Texas, that ill-omened enterprise culminated in a retreat which well-nigh involved the Mississippi squadron in an overwhelming disaster. The Red River was unusually low for the season, and falling instead of rising. There was not, when the army retired, water enough to enable the gun-boats which had ascended the river to repass the rapids at Alexandria. The army could delay but for a limited time, at the end of which, if the boats had not passed, they must be left to their fate. Farragut, who was in New Orleans when the news arrived, wrote bitterly about the blunders made, and was sorely distressed for the issue to the navy. "I have no spirit to write," he says. "I have had such long letters from Porter and Banks, and find things so bad with them that I don't know how to help them. I am afraid Porter, with all his energy, will lose some of his finest vessels. I have just sent him some boats to help him." The boats, however, were saved by the skill and energy of Colonel Joseph Bailey, the chief-of-engineers in Franklin's corps of Banks's army; by whom was thrown across the river a dam, which raised the water on the shoals sufficiently for the boats to cross.

A more pleasant incident occurred to vary the sameness of the blockade days, in the presentation to the admiral, by the Union League Club of New York, of a very handsome sword, with scabbard of massive gold and silver, the hilt set in brilliants. The gift was accompanied by a letter expressive of the givers' appreciation of the brilliant services rendered to the nation, and was a grateful reminder to Farragut, then watching before Mobile for his last grapple with the enemy in his front, that his fellow-countrymen in their homes were not wanting in recognition of the dangers he had incurred, nor of those he was still facing on their behalf.

The time was now close at hand when the weary and anxious waiting, which the admiral afterward so feelingly described, was to be exchanged for the more vigorous action he had so long desired. The co-operation of a division from Canby's army was assured toward the end of July; and at the same time the long-promised, long-delayed monitor ironclads began to arrive. As the want of these and the presence of the enemy's ironclads had been the reasons which, in Farragut's opinion, had made necessary the postponement of the purely naval part of the combined operation, a short description of the vessels which formed so potent an element in his calculations will not be out of place.

The idea of the monitor type of ironclads, which was then the prevalent one in the United States Navy, was brought by John Ericsson from his home in Sweden, where it had been suggested to him by the sight of the rafts with a house upon them crossing the waters with which he was familiar. In its conception, the monitor was simply a round fort, heavily plated with iron, resting upon a raft nearly flush with the water, and provided with the motive power of steam. The forts, or turrets, as they are commonly called, might be one or more in number; and each carried usually two heavy guns, standing side by side and pointing in exactly the same direction, so that if discharged together the projectiles would follow parallel courses. Within the turret the guns could be turned neither to the right nor to the left; if such a change of aim were wished, the turret itself was revolved by steam machinery provided for the purpose. When loading, the port through which the gun was fired was turned away from the enemy; so that if a shot happened to strike at that time it fell on the solid armor. Above the gun-turret there was a second of much smaller diameter, which did not revolve. It was also heavily plated and designed to shelter the commanding officer and those charged with the steering of the ship. So much inconvenience was, however, experienced from smoke and from concussion when these steering turrets were struck, and their dimensions were so contracted, that many captains preferred to remain outside, where they could see better, their orders being transmitted to the helmsmen through the sight-holes pierced in the armor. Of these ironclads, four accompanied Farragut in his attack upon Mobile Bay. Two, the Tecumseh and Manhattan, came from the Atlantic coast, and were sea-going monitors. They had each but one turret, in which they carried two fifteen-inch guns, the heaviest then in use afloat. The other two were river monitors, built at St. Louis for service in the Mississippi. They were consequently of light draught, so much so that to obtain the necessary motive power they each had four screw propellers of small diameter, and they carried four eleven-inch guns in two turrets. Their names were the Winnebago and the Chickasaw. The armor of the two single-turreted monitors was ten inches thick, and that of the river monitors eight and a half inches.

The Tennessee, to which these were to be opposed, was a vessel of different type, and one to which the few ironclads built by the Confederates for the most part conformed—called commonly the broadside ironclad, because the guns, like those of ships-of-war generally, were disposed chiefly along the sides. Her hull was built at Selma, on the Alabama River, and thence towed to Mobile to be plated; it being desirable to take her down the river while as light as possible. She was two hundred and nine feet long and forty-eight feet wide, drawing, as has been said, fourteen feet when loaded. Upon her deck, midway between the bow and the stern, was a house seventy-nine feet long, whose sides and ends sloped at an angle of thirty-four degrees and were covered with iron plating, six inches thick on the forward end and five inches thick on the other end and the sides. With the inclination given, a cannon ball striking would be likely to be turned upward by the iron surface, instead of penetrating. The sloping sides of the house were carried down beyond the point where they met those of the vessel, until two feet below the water. There they turned and struck in at the same angle toward the hull, which they again met six or seven feet under water. Thus was formed all round the ship a knuckle, which, being filled-in solid and covered with iron, was a very perfect protection against any but the most powerful ram. The Tennessee herself was fitted with a beak and intended to ram, but, owing to the slender resources of the Confederacy, her engines were too weak to be effective for that purpose. She could only steam six knots. Her battery, however, was well selected and powerful. She carried on each side two six-inch rifles, and at each end one seven-inch rifle—six guns in all. There were, besides the Tennessee, three wooden gunboats, and Farragut was informed that there were also four ironclads; but this, as regards the lower bay at least, was a mistake.
