twelve inches square, and about five feet distant from each other. Some of these 
gratings are hinged and fitted to open from the inside. 
“ There are ten gun-ports in the casemate—two in the broadside, on either side, 
three forward and three aft. 
“ The forward and after ports, to port and starboard, are placed so as to enable 
the forward and after pivot guns to be used as broadside guns. The directly forward 
and after ports are on a line with the keel. 
“ The ports are elongated and made just wide enough for the entrance of the 
muzzle of the guns in training, and only high enough to allow a moderate elevation 
and depression of the gun. 
** The wooden backing is cut away on each side of the ports inside of the case¬ 
mate, to allow the guns to be trained about one point forward and aft. The gun-ports 
are covered with wrought-iron sliding plates or shutters five inches thick ; those for 
the four broadside guns are fitted in slides. The sliding plates or shutters for 
the pivot-guns are pivoted on the edge, with one bolt that can be knocked out, 
detaching the shutter, if necessary, and are worked by a combination of racks and 
pinions. 
ARMAMENT. 
“ The armament of the c Tennessee 5 consists of six rifled guns, called by the rebels 
Brooks’s rifles. 
“ The two pivot guns are 7i-inch bore, and the four broadside guns are 6-inch 
bore. These guns are reinforced abaft by two wrought-iron bands, two inches thick, 
respectively. Weight of projectiles ninety-five pounds and one hundred and ten 
pounds solid shot. 
“ The pivot guns are fitted on wooden slides, with a rack let into them. On 
an arm attached to the carriage there is a pinion for running out the gun, and by 
raising the arm the rack is thrown out of gear to allow the gun to recoil. 
“ The arrangements for working the battery, and the implements and machinery 
employed, appear to be very good. 
INJURIES RECEIVED IN THE ACTION. 
“ The injuries to the casemate of the ‘Tennessee’ from shot are very considerable. 
On its after-side nearly all the plating is started ; one bolt driven in; several nuts

knocked off inside; gun-carriage of the after pivot gun damaged, and the steering 
rod or chain cut near that gun. There are unmistakable marks on the after part of 
the casemate of not less than nine eleven-inch solid shot having struck within the 
space of a few square feet in the immediate vicinity of that port. On the port side 
of the casemate the armour is also badly damaged from shot. On that side, nearly 
amidships of the casemate, and between the two broadside guns, a fifteen-inch solid 
shot knocked a hole through the armour and backing, leaving on the inside an 
undetached mass of oak and pine splinters, about three by four feet, and projecting
