Having given these general indications of the system of attack and defence adopted in the French navy—by far the most important of all the Continental navies—it now becomes desirable to go more into particulars. It is not necessary to dwell upon the early iron-clads of France. The _Gloire_ and a dozen others of like character were all built of wood, without water-tight bulkheads, without rams or spurs, with armor-plates from four to six inches thick only, and with guns of small calibre and power. They may be left out of consideration in dealing with the present French navy. They were followed by six other vessels, also built of wood, but with upper works of iron, _viz._, the _Océan_, _Marengo_, _Suffren_, _Richelieu_, _Colbert_, _Trident_. They were armored with plates of a maximum thickness of 8½ inches, and carried four guns of 10¾ inches calibre, weighing 23 tons each, with four 16-ton guns, and half a dozen light ones. They varied in some particulars, ranging in tonnage from 7000 to 8000 tons, in horse-power from 3600 to 4600, and in speed from 13 to 14½ knots. The _Friedland_ is another vessel which is frequently classed with the previous six ships, the largest of which she generally resembles, but she is built of iron, and carries eight 23-ton guns, and none of the 16-ton. A committee which sat in 1879, and which had for its president and vice-presidents men no less eminent than the late M. Gambetta and MM. Albert Grévy and Jules Ferry, pronounced these seven ships to be the strongest armored ships of the French navy then in service. Such great advances have since been made, however, that it is only necessary to add respecting these vessels that they were nearly all single-screw ships, and that they carried their principal armament at broadside ports on the main-deck, and in raised barbette towers placed at the four corners of the central battery. The _Richelieu_ was the largest of these vessels. [Illustration: THE “COURBET” (FORMERLY THE “FOUDROYANT”): FRENCH ARMORED SHIP OF THE FIRST CLASS.]
