The Brooklyn and Richmond followed the Hartford, and behind them the gunboat division Sciota, Iroquois, Pinola, Kennebec, Itasca, and Winona, Fleet-Captain Bell having his divisional flag flying on board the Sciota. By this the enemy had better range, and at the same time the smoke of the battle was settling down upon the face of the river. The good fortune which carried through all the vessels of the leading column therefore failed the rear. The Brooklyn lost sight of her next ahead and, as she was passing through the hulks, using both broadsides as they would bear, came violently into collision with the Kineo, next to the last ship of the starboard column--another indication that the two columns were lapping. The gunboat heeled violently over and nearly drove ashore; but the two vessels then went clear, the Brooklyn fouling the booms of the eastern hulks, breaking through them but losing her way. This caused her to fall off broadside to the stream, in which position she received a heavy fire from St. Philip. Getting clear and her head once more up river, the Manassas, which had been lying unseen close to the east bank, came butting into the starboard gangway. The blow was delivered with slight momentum against the chain armor, and appeared at the time to have done little damage; but subsequent examination showed that the Brooklyn's side was stove in about six feet below the water-line, the prow having entered between the frames and crushed both inner and outer planking. A little more would have sunk her, and, as it was, a covering of heavy plank had to be bolted over the wound for a length of twenty-five feet before she was allowed to go outside. At the same time that the Manassas rammed she fired her single gun, the shot lodging in the sand bags protecting the steam-drum. Groping on by the flash of the guns and the light of the burning rafts, the Brooklyn, just clearing a thirteen-foot shoal, found herself close under St. Philip, from whose exposed barbette guns the gunners fled at her withering fire, as they had from that of the Pensacola. The Richmond, a slow ship at all times, was detained by her boilers foaming, and was much separated from her leaders. Still she engaged Fort Jackson and passed through the fire with small loss. The little Sciota followed with equal good fortune, having but two men wounded. The Pinola, which had taken her place next to the Iroquois, was not so fortunate. She engaged first Fort Jackson, from whose fire she received little injury. Then she passed over to the other side within one hundred and fifty yards of St. Philip, from which she at first escaped with equal impunity; but coming then within the light of the fire-rafts, and the greater part of the squadron having passed, the enemy were able to play upon her with little to mar their aim. She was struck fourteen times, and lost three killed and eight wounded, the heaviest list of casualties among the gunboats.
