On the 22d, Commander W. D. Porter, with the iron-clad gunboat Essex, and Lieutenant-Colonel Ellet, with the ram Queen of the West, made another attempt to destroy the Confederate vessel, but the attack though executed with great gallantry under the fire of the batteries, did not succeed. The Essex ran down to Farragut’s fleet, and Farragut having been instructed by the navy department to drop down the river before the water got too low, it was arranged that Commander W. D. Porter should remain below Vicksburg with the Essex and Sumter. On the 28th of July, Farragut arrived at New Orleans, leaving the Katahdin and Kineo at Baton Rouge. On the 5th of August, the Confederates made a vigorous land attack upon the latter place, which was repulsed after a severe contest. The gunboats were not able to assist until toward the close of the action, when they threw their shells directly into the midst of the enemy with great effect. The Arkansas had dropped down the river to take part in the attack, but was not brought into action, one of her engines having broken down. The next morning, Porter, who was then at Baton Rouge with the Essex, moved up to attack her, but before the fight had fairly begun her other engine gave way, and she was run ashore, abandoned, and set on fire by the crew. About an hour afterward she blew up. On the 11th, Farragut sailed for Ship Island and Pensacola, which latter place, having been evacuated by the Confederates, was now made the depot of the Western Gulf Squadron. Commander W. D. Porter remained at Baton Rouge until August 23, when, the town having been evacuated by the Federal troops, he proceeded up the river to reconnoitre batteries reported in progress at Port Hudson, and thence ascended to Bayou Sara to obtain coal, where his boat’s crew was fired upon by guerrillas. Some of the buildings were thereupon burned, and a few days afterward, as the firing was repeated, the rest of the place was destroyed. Afterwards a boat’s crew from the Essex, sent ashore at Natchez to procure ice for the sick, was attacked, by some two hundred armed citizens, one of the sailors being killed, and an officer and five men wounded. Commander Porter immediately opened fire on the town, set a number of houses in flames, and continued the bombardment for an hour, after which the mayor surrendered. On her way down to New Orleans, the Essex had a brisk engagement, on September 7th, with the Port Hudson batteries. In the mean time, several vessels of Captain Farragut’s squadron had been employed on the coast of Texas, where acting volunteer Lieutenant J. W. Kittredge, with the bark Arthur, the little steamer Sachem, and a launch, captured Corpus Christi, after several spirited engagements with the enemy’s batteries, but was unable to hold the town, and was himself made prisoner, September 14, while on shore exploring.
