The Confederate forces which confronted Grant in northern Mississippi during these anxious months interposed between him and Vicksburg, and belonged to the department charged with the defenses of the Mississippi river. As they touched Grant, therefore, on the one side, on the other they were in contact with Farragut's command. The summer passed in various movements by them, threatening Grant's position at Corinth, which culminated on the 3d of October in an attack in force. This was repulsed after hard fighting, and re-enforcements to Grant beginning to come in, the Confederates themselves were thrown on the defensive. The approach of winter, bringing with it higher water and healthier weather on the line of the Mississippi, warned them also that the time was at hand when they might have to fight for the control of the water communications, upon which they no longer had, nor could hope to have, a naval force. Reports therefore began to reach the admiral in Pensacola, from the senior naval officer in the river, that the Confederates were with renewed energy building batteries above Baton Rouge and strongly fortifying Port Hudson.

As there seemed no speedy prospect of obtaining the land force, without whose co-operation an attack upon Mobile would be a fruitless enterprise, Farragut felt his proper position was now in the Mississippi itself. Important as was the blockade service, it was of a character safely to be trusted to a subordinate; whereas the strictly military operations of the approaching campaign, whatever shape they might finally take, would be for the control of the river. It therefore behooved the commander-in-chief of the naval forces to be at hand, ready to support in any way that might offer the effort to obtain control of a region of which the water communications were so characteristic a feature. To push far up a narrow and intricate river a force of ships, whose numbers are insufficient even to protect their own communications and insure their coal supplies, is one thing; it is quite another to repair to the same scene of action prepared to support the army by controlling the water, and by establishing in combined action a secure secondary base of operations from which further advances can be made with reasonable certainty of holding the ground gained. There was no inconsistency between Farragut's reluctance of the spring and his forwardness in the autumn. The man who, to secure New Orleans and compass the fall of the forts, had dared to cut adrift from his base and throw his communications to the winds, because he had an object adequate to the risk, was the same who, six weeks later, had testified his anxiety about communications stretched too far and to no purpose; and now, half a year after that reluctant ascent of the river against his better judgment, we find him eagerly planning to go up again, establishing under the protection of the army an advanced base, from which, with the supplies accumulated at it, further movements may be contemplated with a good chance of final success.

On the 14th of November Farragut reported to the Navy Department his return to New Orleans. The Government, however, had taken warning by the fiasco of the previous season; and, far from urging the admiral on, now sought to impress him with the need for caution. As the great object of opening the Mississippi and obtaining control of it remained, and necessarily must remain, the first of the Government's aims in the Southwest, the result of these instructions was to give Farragut the discretion which had before been denied him. He retained fully his convictions of the summer. "I am ready for anything," he writes to the Department, "but desire troops to hold what we get. General Butler urges me to attack Port Hudson first, as he wishes to break up that rendezvous before we go outside. It will take at least five thousand men to take Port Hudson." In the same spirit he writes home, "I am still doing nothing but waiting for the tide of events, and doing all I can to hold what I have"; and again, a week later, "As Micawber says, I am waiting for something to turn up, and in the mean time having patience for the water to rise." Readiness to act, but no precipitation; waiting for circumstances, over which he had no control, to justify acting, may be described as his attitude at this moment.

On the 16th of December the arrival from the north of General Banks to relieve General Butler—an event which took Farragut much by surprise—gave him the opportunity to show at once his own ideas of the proper military steps to be taken. Banks had brought re-enforcements with him; and three days after his coming the admiral writes to the Department: "I have recommended to General Banks the occupation of Baton Rouge.... It is only twelve or fifteen miles from Port Hudson, and is therefore a fine base of operations. He has approved of the move, and ordered his transports to proceed directly to that point. I ordered Commander James Alden, in the Richmond, with two gunboats, to accompany them and cover the landing." Baton Rouge is on the southernmost of the bluffs which in rapid succession skirt the Mississippi below Vicksburg. With an adequate garrison it became a base of operations from which the army could move against Port Hudson when the time came; and under its protection the colliers and supplies necessary for the naval vessels in the advance could safely remain.

While waiting for the new commander of the army to get fairly settled to work and ready for the combined movement which Farragut was eager to make, the latter was called upon to endure some sharp disappointments. On the 1st of January, 1863, the military forces in Galveston were attacked by Confederate troops, and the naval vessels by a number of river steamboats barricaded with cotton to resist shells fired against them, and loaded with riflemen. The garrison was captured, one of the gunboats blown up by her own officers, and another surrendered after her captain and first lieutenant had been killed on her decks. The other vessels abandoned the harbor. The affair was not only a disaster; it was attended with discreditable circumstances, which excited in the admiral indignation as well as regret. Shortly afterward, two sailing vessels of the squadron, charged with the blockade of Sabine Pass, were also taken by cotton-clad steamers; which to attack availed themselves of a calm day, when the ships were unable to manœuvre. An unsuccessful attempt was made after this to take Sabine Pass; but both that place and Galveston remained in the power of the enemy, and were not regained until the final collapse of the Confederacy. Farragut dispatched one of his most trusted and capable officers, Commodore Henry H. Bell, formerly his chief-of-staff, to re-establish the blockade of Galveston. Arriving off the port toward night, Bell sent one of his detachment, the Hatteras, a light side-wheel iron steamer bought from the merchant service, to overhaul a sail in the offing. Unfortunately, the stranger proved to be the Confederate steamer Alabama, far superior in force to the Hatteras, and after a short engagement the latter was sunk.

All this bad news came in rapid succession, and was closely followed by tidings of the escape from Mobile of the Oreto, which a few months before had eluded the blockading squadron through the daring ruse practiced by her commander. Known now as the Florida, and fitted as a Confederate cruiser, she ran out successfully during the night of January 15th. Here again, though the discredit was less than at Galveston, the annoyance of the admiral was increased by the knowledge that carelessness, or, at the best, bad judgment, had contributed to the enemy's success. From a letter written home at this time by his son, who had not yet returned from the visit begun at Pensacola, it appears that in the intimacy of family life he admitted, and showed by his manner, how keenly he felt the discredit to his command from these events. Though conscious that they were not due to failure on his part to do his utmost with the force given to him, and seeing in the escape of the Oreto a further justification of his own opinion that the lower harbor of Mobile should have been early seized, he nevertheless was "very much worried." This inside view of the effect, visible to those from whom he had no concealments, is supplemented by the description of the admiral's bearing under these reverses given by Captain (now Rear-Admiral) Jenkins, who at this time became his chief-of-staff. "These disasters," he writes, "were sore trials to the admiral, and a less well-poised man would have given way; but they seemed only to give him greater strength of will and purpose.... I myself had the misfortune, after months of watching, to see the Oreto run out the first night after I had been relieved of the command of the Oneida and ordered to report to the admiral as his fleet-captain. I had to bear him these bad tidings. Though no stoic, he bore the news as one accustomed to misfortune." It may seem, indeed, that these events, considered individually, were but instances of the hard knocks to be looked for in war, of which every general officer in every campaign must expect to have his share; and this view is undoubtedly true. Nevertheless, occurring in such rapid succession, and all in that part of his extensive command, the blockade, to which at that moment it seemed impossible to give his principal attention, the effect was naturally staggering. His first impulse was to leave the river and repair in person to the scene of disaster in Texas; but reflection soon convinced him that, however unfortunate the occurrences that had taken place there and elsewhere on the coast, they had not the same vital bearing on the issues of the war as the control of the Mississippi, and therefore not an equal claim upon the commander-in-chief.

At the same time, the effect was to intensify the desire to act—to redeem by success the blot which failures had brought upon his command; and the state of affairs elsewhere on the river was becoming such as to justify enterprise by the reasonable hope of substantial results. A series of circumstances which have been often narrated, and nowhere in a more interesting manner than by General Grant in his personal memoirs, had led to the abandonment of the movement by land upon Vicksburg by the Army of the Tennessee, following the Mississippi Central Railroad. Instead of this original plan of campaign, the Mississippi River was now adopted as the line of advance and of communications. The first move along this new line had been made by General Sherman, who brought with him 32,000 troops, and on the 26th of December, 1862, had landed on the low ground between the mouth of the Yazoo and Vicksburg. On the 29th the army assaulted the works on the hills before them, but were repulsed. Sherman, satisfied that the position there was too strong to be carried, had determined to change his point of attack to the extreme right of the enemy's line, higher up the Yazoo; but the heavy rains which characterized the winter of 1862-'63 in the Mississippi Valley made untenable the ground on which the troops were, and it became necessary to re-embark them. The transports were then moved out into the Mississippi, where they were joined by General McClernand, the senior general officer in the department under Grant himself.

McClernand now decided to attack Arkansas Post, on the Arkansas River, which enters the Mississippi from the west about two hundred miles above Vicksburg. The Post was primarily intended to close the Arkansas and the approach to the capital of the State of the same name; but although fifty miles from the mouth of the river, it was, by the course of the stream, but fifteen by land from the Mississippi. The garrison, being five thousand strong, was thus dangerously placed to threaten the communications by the latter river, upon which the army was to depend during the approaching campaign; and it had already given evidence of the fact by the capture of a valuable transport. This post was reduced on the 11th of January, and McClernand next day started troops up the White River, a tributary of the Arkansas. From this ex-centric movement, which seemed wholly to ignore that Vicksburg and the Mississippi were the objective of the campaign, McClernand was speedily and peremptorily recalled by Grant. The latter, having absolutely no confidence in the capacity of his senior subordinate, could dispossess him of the chief command only by assuming it himself. This he accordingly did, and on the 30th of January joined the army, which was then encamped on the levees along the west bank of the river above Vicksburg.

Serious action on the part of the army, directed by a man of whose vigorous character there could be no doubt, though his conspicuous ability was not yet fully recognized, was evidently at hand; and this circumstance, by itself alone, imparted a very different aspect to any naval enterprises, giving them reasonable prospect of support and of conducing substantially to the great common end. Never in the history of combined movements has there been more hearty co-operation between the army and navy than in the Vicksburg campaign of 1863, under the leadership of Grant and Porter. From the nature of the enemy's positions their forcible reduction was necessarily in the main the task of the land forces; but that the latter were able to exert their full strength, unweakened, and without anxiety as to their long line of communications from Memphis to Vicksburg, was due to the incessant vigilance and activity of the Mississippi flotilla, which grudged neither pains nor hard knocks to support every movement. But, besides the care of our own communications, there was the no less important service of harassing or breaking up those of the enemy. Of these, the most important was with the States west of the Mississippi. Not to speak of cereals and sugar, Texas alone, in the Southwest, produced an abundance of vigorous beef cattle fit for food; and from no other part of the seceded States could the armies on the east banks of the Mississippi be adequately supplied. Bordering, moreover, upon Mexico, and separated from it only by a shoal river into which the United States ships could not penetrate, there poured across that line quantities of munitions of war, which found through the Mexican port of Matamoras a safe entry, everywhere else closed to them by the sea-board blockade. For the transit of these the numerous streams west of the Mississippi, and especially the mighty Red River, offered peculiar facilities. The principal burden of breaking up these lines of supply was thrown upon the navy by the character of the scene of operations—by its numerous water-courses subsidiary to the great river itself, and by the overflow of the land, which, in its deluged condition during the winter, effectually prevented the movement of troops. Herein Farragut saw his opportunity, as well as that of the upper river flotilla. To wrest the control of the Mississippi out of the enemy's hands, by reducing his positions, was the great aim of the campaign; until that could be effected, the patrol of the section between Vicksburg and Port Hudson would materially conduce to the same end.

Over this Farragut pondered long and anxiously. He clearly recognized the advantage of this service, but he also knew the difficulties involved in maintaining his necessary communications, and, above all, his coal. At no time did the enemy cease their annoyance from the river banks. Constant brushes took place between their flying batteries and the different gunboats on patrol duty; a kind of guerrilla warfare, which did not cease even with the fall of Vicksburg and Port Hudson, but naturally attained its greatest animation during the months when their fate was hanging in the balance. The gunboats could repel such attacks, though they were often roughly handled, and several valuable officers lost their lives; but not being able to pursue, the mere frustration of a particular attack did not help to break up a system of very great annoyance. Only a force able to follow—in other words, troops—could suppress the evil. "You will no doubt hear more," the admiral writes on the 1st of February, 1863, "of 'Why don't Farragut's fleet move up the river?' Tell them, Because the army is not ready. Farragut waits upon Banks as to when or where he will go."
