Barriers appeal to the unlearned mind, but they have never obstructed a fleet that was commanded by a determined man. Rafts of big cypress logs were built and anchored in line, and then chain cables taken from the Pensacola Navy Yard were stretched from trees on the Fort Jackson side over these supporting rafts to heavy anchors buried on the east side. Before Farragut arrived the floods of spring and the accumulation of driftwood had broken the barrier, but it was renewed by substituting schooners in place of the rafts where the current was heaviest. In addition to the forts and barrier chain, the Confederates had the support of eleven steamers and a floating battery. This battery was built as an ironclad steamer to carry sixteen heavy guns behind plenty of armor, but there were so many strikes in the shipyard where she was built that she barely got afloat, and she was towed to a place at the forts. Her engines were never used. Had Farragut been delayed ten days more, she would have been a formidable ship, and she would have had a still more formidable consort in another and larger ship of her class that never got afloat. She was called the _Louisiana_, and was commanded by Capt. John K. Mitchell. Another of this squadron was the ram _Manassas_, that under Lieutenant Warley had created a _Manassas_-like panic in the blockading squadron some months before. Two of the squadron belonged to the State of Louisiana. They were called the _Moore_, Capt. Beverly Kennon, and the _McRae_, Capt. Thomas B. Huger. These were cotton-clads--ocean-going steamers protected with cotton bales--very inferior as fighting ships, and yet the able Kennon made a name for himself with the _Moore_. Of the remainder of the squadron it may be said that six were of the “River Defence Squadron”--the guerrillas afloat--and that one of the captains said just before the battle that they were there “to show the naval officers how to fight.”
