The ram now lay at the bend of the river between two forts. On the 22d of July, Flag-Officer Davis sent down to attack her the ironclad Essex, Commander W.D. Porter, with the ram Queen of the West, Lieutenant-Colonel Ellet. They started shortly after dawn, the Benton, Cincinnati, and Louisville covering them by an attack upon the upper batteries. As the Essex neared the Arkansas the bow fasts of the latter were slacked and the starboard screw turned, so that her head swung off, presenting her sharp stem and beak to the broad square bow of the assailant. The latter could not afford to take such an offer, and, being very clumsy, could not recover herself after being foiled in her first aim. She accordingly ran by, grazing the enemy's side, and was carried ashore astern of him, in which critical position she remained for ten minutes under a heavy fire; then, backing and swinging clear, she ran down the river under fire of all the batteries, but was not struck. When Porter saw that he would be unable to ram, he fired into the Arkansas' bows, at fifty yards distance, three solid IX-inch shot, one of which penetrated and raked her decks, killing 7 and wounding 6 of her small crew, which then numbered only 41; the rest having been taken away as she was not fit for immediate service. The Queen of the West rammed, doing some injury, but not of a vital kind. She then turned her head up stream and rejoined the upper fleet, receiving much damage from the batteries as she went back. Two days later, Farragut's fleet and the troops on the point opposite Vicksburg, under the command of General Williams, went down the river; Farragut going to New Orleans and Williams to Baton Rouge. This move was made necessary by the falling of the river and the increasing sickliness of the climate. Porter, on his passage down a fortnight before, had expressed the opinion, from his experience, that if the heavy ships did not come down soon they would have to remain till next season. But the health of the men, who had now been three months up the river, was the most powerful cause for the change. On the 25th of July forty per cent. of the crews of the upper flotilla were on the sick list. The troops, who being ashore were more exposed, had but 800 fit for duty out of a total of 3,200. Two weeks before the Brooklyn had 68 down out of 300. These were almost all sick with climatic diseases, and the cases were increasing in number and intensity. The Confederates now having possession of the point opposite Vicksburg, Davis moved his fleet to the mouth of the Yazoo, and finally to Helena. The growing boldness of the enemy along the banks of the Mississippi made the river very unsafe, and supply and transport vessels, unless convoyed by an armed steamer, were often attacked. One had been sunk, and the enemy was reported to be establishing batteries along the shores. These could be easily silenced, but to keep them under required a number of gunboats, so that the communications were
