CHAPTER XXXVIII. STRENGTH OF THE OPPOSING SQUADRONS AND ARMIES.
Growth of the White Squadron in a Single Decade - Progress of Our Navy a Gratifying Ode after It Was Fairly Started - How the United States Stands in Comparison with the Other Nations of the World - List of Ships in the American Navy - List of Ships in the Navy of Spain at the Beginning of the War - Interest of All Countries Centered on the Result of Our Naval Battles - Modern Guns and Projectiles - The Armies of the Two Combatants - Coast Defenses of the United States.
Three elements enter into the fighting efficiency of nations at war: the strength of their navies, the strength of their armies and the condition of their coast defences. For the first time in many years general attention of the people of the United States was centered upon these conditions when the outbreak of hostilities began to threaten. Inasmuch as it was an admitted fact that most of the fighting would be done at sea, or at least that the efficiency of our fleets would be the most important factor, most of the attention was directed to a study of the navy.
The constructions of what we call the new navy of the United States, "the white squadron," which has placed us sixth in the rank of the naval powers of the world, instead of so far down that we were scarcely to be counted at all, has all been done in less than twelve years. It may be that to stand sixth in rank is not yet high enough, but the progress of a single decade certainly is remarkable.
After the Civil War, when hostilities on our own coast and complications abroad seemed to be at an end, the care of the navy was abandoned and ships were sold with scarcely a protest, almost as entirely as had been done eighty years before, at the end of the Revolution. There was even less reason for this policy, because in 1785 the country was poor and needed the money the ships brought, while in the twenty years following the Civil War there was no such excuse of national poverty. By 1885 there was no United States navy at all worthy the name, for the wooden vessels on the list, with their obsolete guns, were of no value whatever in the event of hostilities with a foreign power that had kept up its equipment with rifled guns and ironclads.
The movement to repair the decay began when, in 1881, Secretary of the Navy William H. Hunt appointed the first advisory board, presided over by Rear-Admiral John Bodgers, "to determine the requirements of a new navy." This board reported that the United States should have twenty-one battleships, seventy unarmored cruisers of various sizes and types, twenty torpedo boats, five rams and five torpedo gunboats, all to be built of steel. The report was received by Congress and the country with the attention it merited, but to get the work started was another matter.
POLICY OF THE ECONOMISTS.
The economists had been praising the policy of idleness in naval construction, claiming first that we were at peace and did not need to spend money on expensive vessels and, next, that naval construction was in an experimental stage and that we should let the European nations go to the expense of the experiments, as they were doing, and when some result had been reached, take advantage of it, instead of wasting our own money in work that would have to be thrown away in a few years.
When the country became convinced that a navy was needed, it was found that we could not follow out that pleasant little theory. Our naval authorities could not obtain the facts and the experience they wanted from other nations, and our shipyards could not build even one of the armored ships. We could not roll even the thinnest of modern armor-plates, and could not make a gun that was worth mounting on a modern vessel if we had it.
The shipyard of John Roach did the first work on the new navy, and during Secretary Chandler's term of office built the Chicago, the Boston, the Atlanta and the Dolphin. Instead of battleships, the first of the fleet were third-rate cruisers. Armor-plate was bought in a foreign market, and we actually went abroad for the plans of one our largest cruisers - the Charleston.
In 1885 the navy department came under the administration of Secretary William C. Whitney, and it was beginning with his years of service that the greatest progress was made. While our shipyards were learning to build ships, the gunmakers and the makers of armor-plate were learning their craft too, so that progress was along parallel lines. In 1886 the sum of $2,128,000 was appropriated for modern rifled guns. The first contract for armor-plate was signed in 1887. Since that time the plants for construction have been completed and armor-plate equal to the best in the world turned out from them. Ten years of apprenticeship have taught us how to build whatever we need to carry on naval warfare.
TAKES THE RANK OF SIXTH.
By 1894 the United States had risen to the sixth among the naval powers of the world, the first ten and their relative strength expressed in percentage of that of Great Britain being as follows:
Great Britain 100 United States 17
France 68 Spain 11
Italy 48 China 6
Russia 38 Austria 5
Germany 21 Turkey 3
Since that time the relative position of the leaders has not
materially changed, although some estimates are to the effect that
Russia and Italy have changed places and that Spain has gained
slightly on the United States. Of the ones at the foot of the
procession all have dropped below the station assigned them, by the
advance of Japan, which has come from outside the file of the first
ten and is now eighth, ranking between Spain and China. The estimates
are based on a calculation of all the elements that enter into the
efficiency of the navies, such as tonnage, speed, armor, caliber and
range of armament, number of enlisted men and their efficiency. Such
calculations cannot be absolute, for they cannot measure at all times
the accuracy of the gunnery of a certain vessel. The human equation
enters so prominently into warfare that mathematical calculations must
be at all times incomplete. Americans will be slow to believe,
however, that they are at any disadvantage in this detail, whatever
their material equipment may be.
The following table shows the strength of the navy of the United
States. In that part of the table marked "first rate" the four ships
placed first are first-class battle ships, the Brooklyn and New York
are armored cruisers, the Columbia, Olympia and Minneapolis protected
cruisers, the Texas a second-class battle ship and the Puritan a
double-turret monitor. Among the second- raters all but the
Miantonomah, Amphitrite, Monadnock and Terror (monitors) are protected
cruisers. The newly bought boats, New Orleans and Albany, belong in
this class. The third-raters are a heterogeneous lot, consisting of
cruisers, gunboats, old monitors and unprotected cruisers. Of the
fourth raters, Vesuvius is a dynamite ship, the Yankee and Michigan
are cruisers, the Petrel, Bancroft and Pinta are gunboats and the Fern
is a transport. The remaining classes of the table are homogeneous.
The government has recently purchased numerous tugs and yachts not
accounted for in the table:

SPAIN'S NAVY IS A WEAKER ONE.
Spain's navy is decidedly weak when compared with that of the
United States. A mere glance at the two tables will be sufficient to
show the difference. Spain's list of unarmored cruisers is long, but
four of our battle ships or swift, modern, armored cruisers could blow
the lot out of the water. In torpedo boats we compare favorably with
Spain. In one respect Spain is stronger, that is in her six speedy
torpedo boat destroyers. This table accounts for every war ship Spain
has, to say nothing of the few antique merchantmen of the Spanish
liner company which can be turned into cruisers.

INTEREST IN THE WORKING OF MODERN WAR SHIPS.
The puzzle that was troubling every naval authority as well as
every statesman in the civilized world, at the outbreak of the war
between the United States and Spain, was what would be the results of
a conflict at sea between the floating fortresses which now serve as
battle-ships. Since navies reached their modern form there had been no
war in which the test of the battle-ship was complete. Lessons might
be learned and opinions formed and prophesies made from the action of
battle-ships in the war between China and Japan, the war between Chili
and Peru, and from the disasters which had overtaken the Maine in the
harbor of Havana and the Victoria in her collision with the
Camperdown, as well as the wreck of the Reina Regente and others. But
in all these, combine the information as one might, there was
insufficient testimony to prove what would happen if two powers of
nearly equal strength were to meet for a fight to a finish.
Whatever was uncertain, it was known at least that there would be
no more sea fights like those of the last century and the first half
of this, when three-deck frigates and seventy-four-gun men- of-war
were lashed together, while their crews fought with small arms and
cutlasses for hours. Those were the days when "hearts of oak" and "the
wooden walls of England" made what romance there was in naval warfare,
and the ships of the young United States won respect on every sea. In
the fights of those days the vessels would float till they were shot
to pieces, and with the stimulus of close fighting the men were ready
to brave any odds in boarding an enemy's craft. It was well understood
that the changed conditions would make very different battles between
the fighting machines of to-day.
That a naval battle between modern fleets, armed with modern guns,
would be a terribly destructive one both to the ships and to the
lives of those who manned them, was conceded by all naval
authorities. The destructiveness would come not only from the
tremendous power and effectiveness of the guns, but also from the
fact that the shell had replaced the solid shot in all calibers down
to the one-pounder, so that to the penetrating effect of the
projectile was added its explosive power and the scattering of its
fragments in a destructive and death-dealing circle many feet in
diameter.
MODERN GUNS AND PROJECTILES.
The modern armor-piercing shell, made of hardened steel, and with
its conical point carefully fashioned for the greatest penetrating
power, has all the armor-piercing effectiveness of a solid shot of
the same shape, while its explosiveness makes it infinitely more
destructive. For the modern shell does not explode when it first
strikes the side or armor of an enemy's ship, but after it has
pierced the side or armor and has exhausted its penetrative effect.
The percussion fuse is in the base of the shell, and is exploded by a
plunger driven against it by the force of the impact of the shell on
striking. The time between the impact of the shell and its explosion
is sufficient for it to have done its full penetrative work.
It first must be understood that all modern guns on ships-of-war
are breech-loading and rifled, and that the smooth bore exists only
as a relic, or to be brought out in an emergency for coast defense,
when modern guns are not available. From the thirteen- inch down to
the four-inch, the guns are designated by their caliber, the diameter
of their bore, and the shot they throw, while from that to the
one-pounder they take their name from the weight of the shot.
Everything below the one-pounder is in the machine-gun class.
The base of rapid-fire work is the bringing together in one
cartridge of the primer, powder, and shell. When the limit of weight
of cartridge, easily handled by one man, is reached, the limit of
rapid-fire action is also reached; and, although the quick-moving
breech mechanisms have been applied abroad to guns of as large as
eight-inch caliber, such guns would rank as quick, rather than rapid
firing, and would require powder and shot to be loaded separately.
On the modern battleships the function of the great guns is the
penetration of the enemy's armor, either at the waterline belt or on
the turrets and gun positions, while that of the rapid-firers is the
destruction of the unarmored parts or the disabling of the guns not
armor protected. The six, three, and one-pounders direct their rain of
shots at the turret portholes, gun shields, or unprotected parts of
the ship, having also an eye to torpedo- boats, while from the
fighting tops, the Gatlings rain a thousand shots a minute on any of
the crew in exposed positions. With such a storm of large and small
projectiles it would seem to be rather a question of who would be left
alive rather than who would be killed.
The guns in use in the United States navy are the 13-inch, 12-
inch, 10-inch, 8-inch, 6-inch, 5-inch, 4-inch, 6-pounders, 3-
pounders, 1-pounder, Hotchkiss 37 mm. revolver cannon, and the
machine guns. In the following table is given the length and weight
of these guns, as well as of the shell they carry:

HOW THE BIG GUNS ARE USED.
The 14-pounder, although not included in the navy armament, is
given for the purpose of comparison, since it is with guns of this
caliber that some of the Spanish torpedo-boat destroyers are armed.
The largest gun as yet mounted on our largest torpedo-boats is the
6-pounder, while a single 1-pounder is the gun armament of the
ordinary torpedo-boat. The Hotchkiss revolver cannon is not given in
the table because its caliber, etc., is the same as that of the
1-pounder, and, in fact, the latter has superseded it in the latest
armaments, so that it is now found only on the older ships of the
modern fleet. The machine guns are not given because their effective
work is practically the same. The Gatling is of 45-caliber, and uses
the government ammunition for the Springfield rifle.
A look over the table shows some general principles in the matter
of powder and shell used. The powder charge is about half the weight
of the shell, while the length of the shell is a little over three
times its diameter.
To attain its extreme range a gun must be given an elevation of
about fifteen degrees. The greatest elevation given any of the guns
on shipboard is about six degrees. This limit is made by two
factors - the size of the portholes or opening in the turrets for the
larger guns, and the danger of driving the gun backward and downward
through the deck by any greater elevation. The practical range of the
great guns of a ship, the ten, twelve, and thirteen- inch, is not,
therefore, believed to be over five or six miles, and even at that
range the chances of hitting a given object would be very small. A
city could, of course, be bombarded with, effect at such a range,
since a shell would do tremendous damage wherever it might strike, but
a city to which a ship could approach no nearer than say seven miles
would be safe from bombardment.
The muzzle velocities given the shells from the guns of the navy
are something tremendous, while the muzzle energy is simply
appalling. The shell from the thirteen-inch gun leaves the muzzle at
a velocity of 2,100 feet a second, and with an energy of 33,627-foot
tons, or the power required to lift one ton one foot. From this
velocity the range is to 1,800 feet a second in the one- pounder,
although from the three-pounder at 2,050 feet it averages about the
same as the thirteen-inch. The five-inch rapid-fire gun has the
greatest muzzle velocity at 2,250 feet. The muzzle energy is, of
course, small in the smaller guns, being only twenty-five- foot tons
in the one-pounder and 500 tons in the fourteen-pounder.
The power of penetration has already been given in a general way,
but the power of penetration of steel is much greater. At its muzzle
velocity the thirteen-inch shell will penetrate 26.66 inches of steel,
the twelve-inch, 24.16 inches; the ten-inch, 20 inches, and the
five-inch, 9 inches. The one-pound shell bursts in piercing one-fourth
and nine-sixteenths-inch plates, scattering its fragments behind the
target.
It may be interesting to note that the cost of one discharge of a
thirteen-inch gun is $800, and that when a battleship like the
Massachusetts lets loose her entire battery, both main and secondary,
the cost of a single discharge is $6,000.
