Armored belt and redoubt. Ram bow and dome stern. The belt of the Redoubtable encircles the water-line to the height of the main-deck beams, curving down forward over the point of the ram; that of the other two ships stops short of the curve of the counter in an armored bulkhead, the lower edge being carried on by an armored deck to protect the steering-gear. The sides forward and abaft the redoubt are given a rank tumble home, the redoubt rising straight to the spar-deck, thus giving clear fore-and-aft and beam fire from the main-deck battery. A heavy gun is mounted in barbette on top of the redoubt, each side, having a clear firing angle of 180°; the gun-slide alone is protected by armor, while a musket-proof shield is mounted on the forward part of the slide, as protection to the crew. On the spar-deck is carried a battery of light rifles in broadside. [Illustration: DEVASTATION.] TRIDENT. FRIEDLAND. [Illustration: TRIDENT.] Armored belt and casemate. Ram bow and dome stern. The belt encircles the water-line to the height of the main-deck beams. The casemate rises to the height of the spar-deck beams. At the forward end of the casemate, on each side, a barbette unarmored half-turret is built, being simply a projecting shelf for mounting a heavy gun. The sides from the main-deck up forward are given a sharp tumble home to permit clear forward fire; while aft the spar-deck rail is placed inboard about three feet, leaving a clear fire aft, giving the part of the spar-deck outside the rail the appearance of a continuous channel-piece. The turret guns are only protected by a light musket-proof shelter, rising above the slide. There is a light battery of broadside rifles on the spar-deck, a bow-gun working in one port under the forecastle, and a similar stern-gun. There is no forward or after fire from the main-deck battery. COLBERT. Of the same type as the Friedland, except that in place of the barbette half-turrets there are armored breastworks for the protection of a heavy bow and a heavy stern-gun on the spar-deck. [Illustration: COLBERT.] RICHELIEU. MARENGO. OCEAN. SUFFREN. [Illustration: SUFFREN.] Armored belt and casemate, with four armored barbette turrets. Ram bow, straight stern. The belt encircles the water-line, coming to but not covering the ram, which is a solid bronze casting. The barbette turrets are just over the corners of the casemate, projecting nearly half their diameter clear of the side for fore-and-aft fire. The side is not broken in or given a tumble home, as the muzzles of the turret guns are above the spar-deck rail. The Richelieu has twin screws, the others single ones. There is no fore-and-aft fire from the casemate. Light spar-deck broadside battery. Armored commander’s lookout. BAYARD. TURENNE. LA GALLISSONNIERE. TRIOMPHANTE. VICTORIEUSE. VAUBAN.
