Meanwhile the Brooklyn was lying bows on to the fort, undergoing a raking fire and backing down upon the starboard bow of the Richmond, whose engines were stopped, but the vessel drifting up with the young flood-tide. Her captain, seeing a collision in such critical circumstances imminent, gave the order to back hard both his own ship and her consort; fearing that, if the four became entangled, not only would they suffer damage themselves, but, if sunk by the fire of the fort, would block the channel to the rest of the squadron. As she backed, the Richmond's bow fell off to port, bringing her starboard broadside fairly toward the fort and batteries, on which she kept up a steady and rapid fire, at a distance of from three hundred to one hundred and fifty yards, driving the enemy out of the water-battery and silencing it; being at the same time wrapped in a cloud of smoke which hid her hull and rose above her lower mast-heads. As her topmasts were down, the ship was thus so completely hidden that Buchanan, the Confederate admiral, who had had her captain under him as a midshipman in days long gone by, and again as first lieutenant of a corvette during the war with Mexico, asked after the surrender: "What became of Jenkins? I saw his vessel go handsomely into action and then lost sight of her entirely." While thus backing and fighting the ship was in great danger of getting aground, having at times less than a foot of water under her keel; but her commander thought the situation so critical as to necessitate the risk. During the same time the Brooklyn, from her unfortunate position, was unable to use any but her bow guns, and, even when her hull was obscured by the smoke of the battle, her position was shown to the gunners of the fort by her tall spars towering above. These moments of anxiety were ended when she brought her head once more in the right direction and steamed on; the Richmond followed with the other ships of the port column, which had closed up and joined in the action during the delay. Their fire, with the monitors', kept down that of the fort until the bulk of the fleet had gone by, but when the heavier ships were out of range the enemy returned to their guns and severely punished the rear of the line; the last ship, the Oneida, receiving a VII-inch rifle shell, which passed through her chain armor and into the starboard boiler, where it burst, the larger part of the watch of firemen being scalded by the escaping steam. About the same moment a similar projectile burst in the cabin, cutting both wheel-ropes, while her forward XI-inch gun and one of the VIII-inch were disabled. In this condition the Oneida was pulled past the forts by her consort, the Galena.
