After his great battle Captain McGiffin, a mental and physical wreck, came to America to die. He met death as a brave man should, with but one regret: He wished that he might have had one chance to fight for his own country, with a Yankee crew at his back and a Yankee ship under him.
OUR NEW NAVY.
Since the last of the naval battles recorded in preceding chapters was fought, the advance in ships, engines, and guns has been such that warships of the past are considered obsolete; while the introduction of smokeless powder and projectiles containing heavy charges of dynamite or gun-cotton has increased the efficacy of modern ordnance.
The use of armor for ships is so recent, only dating from the time of our civil war, that modern war-ships have been little in action. In fact the war between England and the United States, in 1812-15, was the last important naval war previous to the introduction of steam. The revolution in naval tactics caused by steam was very great, but our civil war afforded little experience in fleet actions, the important naval affairs being for the most part attacks of fleets upon land fortifications. The only fairly well-matched, stand-up fight of that war between vessels was that of the Kearsarge and Alabama.
Steel has come into use for the hulls of vessels—and the invention, by our own citizens, of nickel-steel, and of the Harvey process for plates, has caused a revolution in the application of defensive armor.
We may instance the armor for the battle-ship Maine, which vessel carried on her sides alone four hundred and seventy-five tons of metal—Harveyized nickel steel. The plate which was tried at the Naval Proving Ground, at Indian Head, on the Potomac, and upon the proof of which depended the receiving of the whole quantity from the contracting company, was thirteen feet seven inches long, seven feet wide, and twelve inches in thickness at the top, tapering to six inches. These measurements may give some idea of the tremendous power of the implements employed in forging and tempering such a mass of metal.
It successfully resisted four shots from an eight-inch rifled gun, firing, at only a few yards’ distance, the best armor-piercing shot, breaking the latter to fragments. Then a ten-inch gun was tried upon the same plate. Again the shot was broken up, and the plate, already hit four times before, was cracked, but remained still capable of affording perfect protection. It is not at all probable that any one plate would be hit five times in the course of an action—and so this armor is considered as near perfection as it is possible for metallurgists to come, in the present state of knowledge. The Maine and Texas, and the battle-ships of the Iowa class, as well as the great monitors, Puritan and Monadnock, all of which vessels are of the latest construction, have these plates, thereby saving much weight, and allowing of additional armor protection to the upper works. The heavy armor extends from one barbette to the other, in the Iowa being about 180 feet, and from four and a half feet below the water line to three feet above it. At the level of the belt is a curving steel deck, three inches thick, to deflect plunging shot; while the mass of coal is so arranged in the bunkers as to protect the boilers and machinery.
The Iowa carries four 12-inch rifles, mounted in pairs in two turrets, eight 8-inch rifles, also mounted in pairs in turrets, six rapid-fire 4-inch rifles, and an ample secondary battery of twenty 6-pounder and six 1-pounder rapid-fire guns, and two gatlings—all high powered breech-loading guns of the best American manufacture.
In the last few years there have also been great changes and improvements in different forms of explosives, the development of torpedo boats and torpedo-catchers, and modes of defence against such attacks. Almost all the large vessels have double bottoms, divided in many separate cells like honeycombs—and packed with a preparation of cocoa-nut fibre, which swells when in contact with water, thus effectually stopping shot holes. There are also many transverse bulkheads, making many compartments of the vessel’s hull; while the engines are so cut off by them that one is independent of any injury to the other. There are also many small engines, for various purposes, and electric light makes the deepest part of the interior of the great ship’s hull as plain as the upper deck, in full sunlight. Lastly, the great increase in speed and power of engines tend to make the war-ship a very different thing from what she was at the time spoken of in the previous chapter.
