The steamers of the mortar flotilla, and the sailing sloop Portsmouth, as soon as the flag-ship had lifted her anchor, moved up into the station which had been assigned them to cover the passage of the fleet, about five hundred yards from Jackson, in position to enfilade the water battery commanding the approach to the fort. The vessels kept their place, firing shrapnel and shell, until the last of the fleet was seen to pass the forts. They then retired, the mortar-schooners at the same time ceasing from the shelling, which had been carried on throughout the engagement. An hour and a quarter had elapsed from the time that the Cayuga passed the obstructions. The fleet, arriving above the forts, fell in with the Confederate flotilla, but in the absence of the Louisiana the other Confederate steamers were no match for their antagonists. The Cayuga indeed, dashing forward at a rate which left her but fifteen minutes under the fire of the forts, found herself when above them in hot quarters; and in a not unequal match rendered a good account of three assailants. The Varuna, passing with yet greater rapidity, steamed through with her guns trained as far ahead as they could be, and delivered her fire as opportunity offered. She soon passed beyond them, unsupported, and continued up the river, coming close upon a steamer called the Doubloon, in which were General Lovell and some of his staff, who narrowly escaped being captured. After the Varuna came the Governor Moore, which had been down among the Union fleet, receiving there the fire of the Oneida and Pinola. Finding the berth too hot for him, and catching sight of the Varuna thus separated from her fleet, Kennon hoisted the same lights as the latter vessel and followed on up. The lights deceived the Varuna and also the Confederate steamer Jackson, which had been up the river on duty and was at quarantine as the two others drew near. Taking them for enemies the Jackson opened a long-range fire on the two impartially, one of her shots wounding the fore-mast of the Moore; she then steamed hastily away to New Orleans, where she was destroyed by her commander. The only other vessel in sight was the Stonewall Jackson[7] of the River Defence Fleet, carrying one gun. She was behind the two, trying to escape unseen to New Orleans. Kennon now opened fire, hoping that the Jackson, undeceived, would turn back to help him, but she kept on her upward course; the Varuna, however, was no longer in ignorance. Finding that the height of the Moore's forecastle out of water and the position of the bow gun would not let it be depressed enough to fire with effect, Kennon resorted to the old-time heroic treatment for such defects; loading the gun with percussion shell he fired it through the bows of his own ship, and used the hole thus made for a port. The next shot raked the Varuna's deck, killing three and wounding nine of the crew. Boggs then put his helm hard aport, bringing his starboard
