On the 18th of June the squadron was assembled just below Vicksburg, having in company also seventeen schooners of the mortar flotilla, still under Porter's command. These were placed as rapidly as possible in suitable positions on the two sides of the river, opened fire on the 26th, and continued it through the 27th. Upon the evening of the latter day Porter notified the flag-officer that he was ready to cover, by a steady bombardment, the intended passage of the fleet before the batteries.
Vicksburg is situated on the first high land met on the east bank of the Mississippi after leaving Memphis, from which it is four hundred miles distant. The position was one of peculiar strength and importance for commanding the navigation of the river. Not only was it exceptionally lofty, and on one flank of that series of bluffs which has before been mentioned as constituting the line upon which the Confederate grip of the stream was based, but the tortuous character of the channel gave particular facilities for an enfilading fire on vessels both before and after they came abreast the works. They were thus exposed to a longer and more dangerous cannonade than is the case where the stream flows straight past the front of a battery. The channel has now changed; but in 1862 the river, which from Memphis had pursued its winding course through an alluvial country, made when abreast of Vicksburg a sharp turn to the northeast, as though determined to reach the bluffs but four miles distant. As it neared them it swung round with a sharp turn to the southwest, parallel to its recent direction, flowing for the most part close to the foot of the hills. Between the two reaches, and formed by them, immediately opposite the town, there was a low tongue of land, or promontory, four miles long and less than one wide. The squadron, being below, had to steam up through the lower reach against the current, make the sharp turn at the bend, and then pass through the upper reach. In the bend it was followed by a fire from the highest part of the bluffs, to which it could make no reply.
Passage of Vicksburg Batteries, June 28, 1862. Order of Attack.
At 2 a. m. of June 28th the signal was given, and at three the squadron was under way—eleven vessels, of which three were the heavy ships Hartford, Richmond, and Brooklyn; two, the corvettes Iroquois and Oneida; and six gunboats. At four, the ships in their slow progress, stemming the current, had passed the mortar schooners; and the latter then opened fire, as did the steamers connected with them, which were not to attempt the passage. Owing to a misunderstanding, the three vessels which formed the rear of the column, the Brooklyn and two gunboats, did not get by. The others, at 6 a. m., anchored above Vicksburg. Though exposed much of the time to a raking fire, to which they were not able to reply, the vessels suffered less than would have been expected, owing to the enemy falling into the common mistake of giving too much elevation to his guns. Having thus accomplished his instructions, Farragut reported coldly to the Department that, in obedience to the orders "and the command of the President, I proceeded up to Vicksburg with the Brooklyn, Richmond, and Hartford, with the determination to carry out my instructions to the best of my ability.... The Department will perceive from this report that the forts can be passed, and we have done it, and can do it again as often as may be required of us. It will not, however, be an easy matter for us to do more than silence the batteries for a time, as long as the enemy has a large force behind the hills to prevent our landing and holding the place." "I am satisfied," he says again, "it is not possible to take Vicksburg without an army of twelve or fifteen thousand men. General Van Dorn's division (Confederate) is here, and lies safely behind the hills. The water is too low for me to go over twelve or fifteen miles above Vicksburg." The last sentence reveals clearly enough the madness of attempting to take three of the best ships of the navy to the upper river in falling water. Fortunately the insufficient depth now was above—not below—them, and they were not utterly cut off from the sea. Commander Porter, however, who started down river a week later, in compliance with orders summoning him to Washington, and than whom the navy had no more active nor enterprising officer, wrote back to the flag-officer that if the big ships did not soon return he feared they would have to remain till next year.
Three days after Farragut passed the batteries of Vicksburg, on the 1st of July, the Mississippi flotilla, under the command of Flag-officer Charles H. Davis, joined him from above; having left Memphis only two days before, but favored in their voyage by the current, by competent pilots, and by a draught suited to the difficulties of river navigation. The united squadrons continued together until the 15th of July, lying at anchor near the neck of the promontory opposite Vicksburg; with the exception of the Brooklyn and the two gunboats which had not passed up on the 28th of June. These remained below the works, and on the opposite side of the promontory.
The position of the two flag-officers was about four miles below the mouth of the Yazoo River, a tributary of the Mississippi, which enters the main stream on the east side not far above Vicksburg. It was known to them that there was somewhere in the Yazoo an ironclad ram called the Arkansas; which, more fortunate than the Mississippi at New Orleans, had been hurried away from Memphis just before that city fell into the hands of the United States forces. She was a vessel of between eight hundred and a thousand tons burden, carrying ten guns, which were protected by three inches of railroad iron, backed by bales of compressed cotton firmly braced. Her most dangerous weapon, however, was her ram; but, owing to the lightness and bad construction of the engines, this was not as formidable as it otherwise might have been to the enemy's ships.
So little injury had thus far been done to the United States vessels by the rams of the Confederates that the two flag-officers were probably lulled into a state of over-security, and they allowed their squadrons to lie with too low fires. To this doubtless contributed the more powerful motive of the difficulty to the coal supply incurred by the excessively long line of exposed communications, imposed upon both squadrons by the stubborn persistence of the Navy Department in hurrying the fleets far in advance of any support by the army. Beyond the reach of their guns they could not control the river banks; and, unless they could be present everywhere along the eight hundred miles which separated Memphis from New Orleans, even the narrow strip on either side swept by their cannon was safe at any point only while they were abreast it. The moral effect of their promenade up and down and of their meeting at Vicksburg was accurately weighed by the enemy; and, however it may have imposed upon the Northern people, did nothing to insure the safety of the unarmed vessels upon which supplies depended. This essentially vicious military situation resulted necessarily in a degree of insecurity which could have but one issue—a retreat by both squadrons toward their respective bases, which soon after followed.
Convinced of the inutility of his own presence at Vicksburg, and preoccupied with the risks threatening his squadron from the unguarded state of the river and its dangerous navigation, it is not wonderful that Farragut, who was the senior of the two flag-officers, thought little of the single ironclad vessel in his neighborhood. He was not prone to exaggerate danger, and his experience had not led him to entertain any high opinion of the enemy's rams. To these circumstances he owed one of the most mortifying incidents of his career.
