Of the above ships it may be remarked that the _Thetis_ and _Reine
Blanche_ have been nearly twenty years afloat, the _Galissonière_ was
launched in 1872, the _Victorieuse_ in 1875, and the _Triomphante_
in 1877. The remainder of the nine, as previously stated, are modern
vessels, the _Duguesclin_ being not yet completed. The _Duguesclin_
and her sister ships are of the _Duperré_ type, much reduced in
dimensions.
There are nine completed coast-guard iron-clads and eight armored
gun-boats in the French navy, as follows:

The vessels in the tables C and D are all revolving-turret vessels,
with the exception of the _Taureau_ and of the four second-class
gun-boats, which fire their guns _en barbette_. They embrace very
different types of construction, involving different degrees of
sea-worthiness—very low degrees in some of them, I fear. With the
exception of the _Tempête_, they are all furnished with twin screws.
The _Fulminant_, _Tonnerre_, _Tempête_, and _Vengeur_, in Table C,
and the whole of the vessels in Table D (as yet incomplete), are
of iron or of steel, or of the two combined; the remainder have
hulls principally built of wood. I have chosen for illustration the
turret-vessel _Vengeur_, as seen on page 87, which has been engraved
from a photograph sent to me by a naval friend in France.
We come now to the unarmored ships of France, and as in writing of
these I purpose accepting the official classifications adopted in
France, which are not identical with those employed in England, it
may be well to repeat here a caution which the British Admiralty
has given in a memorandum prefixed to a recent “return” of theirs
“showing the fleets of England, France, Russia, Germany, Italy,
Austria, and Greece.” The caution is to the effect that France
includes under the heading of “cruisers” vessels of about similar
value to the larger class of English sloops, which are excluded from
the English “cruiser” class. But I regret the necessity of observing
that the Admiralty officers, while careful to put this explanation
well forward, appear to be equally careful to withhold an explanation
of much greater moment concerning three French cruisers of large size
and of greater importance—withheld in pursuance, apparently, and as
I have most reluctantly come to fear, of an uncandid, and indeed of
a misleading spirit, which seems to have taken possession of some
persons who have to do with the preparation of Admiralty returns to
Parliament. The exercise of this spirit has forced me ere now to draw
the attention of Parliament to the matter, and in one instance to
have an official return, which contained erroneous and too favorable
classifications of British ships, withdrawn.
Any one referring to the Parliamentary return of British and foreign
fleets just adverted to will find under the heading of “Unarmored
Vessels Building” two large and remarkably fast steel cruisers, the
_Tage_ and the _Cécile_, the former of which exceeds 7000 tons in
displacement, while the latter approaches 6000 tons, and both of
which are to steam at the immense speed of 19 knots an hour, or a
knot in excess of the fastest armed vessel (neglecting torpedo craft)
in the British navy. These two French cruisers are respectively 390
and 380 feet in length, and are to be driven by over 10,000 indicated
horse-power in the _Tage_, and by nearly 10,000 indicated horse-power
in the _Cécile_. A third vessel, the _Sfax_, launched at Brest in
1884, of 4420 tons, 7500 indicated horse-power, and 16½ knots speed,
is also given without remark in the Parliamentary return as an
“unarmored” vessel. Now even this last-named vessel has a steel deck
one and three-fourths inches thick to protect her boilers, machinery,
and magazines, while the _Tage_ and _Cécile_ have such decks three
inches thick. These, being mere decks, do not, of course, remove
the ships out of the category of unarmored ships, and the return is
correct in this respect. But now in this same return all the British
ships provided with protecting decks of this character are kept out
of the lists of unarmored or “unprotected” vessels, and are classed
separately, and are described as “protected” vessels. And not only is
this true of vessels like the _Mersey_ class, which have such decks
two and one-half inches thick in places, but it is true likewise of
some twenty vessels, ranging, many of them, as low as 1420 tons in
displacement, and with decks and partial decks of less thickness than
that of the _Sfax_, the weakest of the three French ships in this
respect. In short, while the twenty-two English ships are withheld
from the category of unarmored ships, although every one of them is
inferior in protecting decks to the three French ships, the latter
are placed in the inferior category, and not a word of explanation
is offered to prevent the uninitiated and unsuspecting reader from
regarding as weaker than our vessels those French vessels which
are in fact the strongest and best protected. I must say that, as
an Englishman, I grieve to see returns to the British Parliament
made use of for the dissemination of information so misleading as
this; and I should do so if I could believe there was nothing but
official negligence involved; but I am sorry to say I cannot doubt
that had the mere reproduction of foreign classifications put three
of the very fastest and most important cruisers of our own navy, of
Admiralty origin, at the very great disadvantage to which the French
ships are put in this return, we should have had a very full and a
very prominent explanation of the seeming discrepancy given. It is
to the credit of _Lloyd’s Register_ office that what the Admiralty
Office failed to do in a paper issued at the end of July was properly
done in their _Universal Register_, published two or three months
earlier; for in the latter the three French ships are separately
detailed under the heading of “Deck-protected Cruisers.”
[Illustration: THE “VENGEUR:” FRENCH IRON-CLAD COAST-GUARD VESSEL.]
It is absolutely necessary to bring to light the matter just
explained, for otherwise the present state and the prospects of the
French navy cannot be properly understood, the _Tage_, _Cécile_, and
_Sfax_ being, on the whole, the most important of the French ships
which are without armor-belts. Two others there are, however, which
are weaker than the _Tage_ and _Sfax_ only in the fact of their being
without special deck protection. These are the _Duquesne_ and the
_Tourville_, two ships approximately alike in size and construction,
and both having their iron bottoms sheathed with two thicknesses of
wood and then coppered, after the manner introduced by myself in
H.M.S. _Inconstant_. Both of these French ships have attained 16-9/10
knots of speed. They are armed with seven guns of eight tons and
fourteen of three tons weight.
The remaining unarmored vessels of France must be rapidly summarized.
It is impossible to neglect in this case, as was done in my article
on the British navy, all the frigates, etc., which have frames of
timber, because to do this would be to omit all unarmored frigates of
the French navy except the _Duquesne_ and the _Tourville_, already
described. But it is not necessary to do more than name the _Venus_,
_Minerve_, and _Flora_, all launched prior to 1870, and all slow,
and to say that there remain but four unarmored wood frigates of 14
knots speed, of about 3400 tons, and armed with from two to four
guns of five tons, and eighteen to twenty-two guns of three tons.
These are _Aréthuse_, _Dubourdieu_, _Iphigénie_, and _Naïade_,
which, although wooden ships, have all been launched since 1881—the
_Dubourdieu_ in 1884. Of French first-class cruisers which do not
rank as frigates (having no main-deck batteries) there are nine in
number, all built of wood except one, the _Duguay-Trouin_, which is
the fastest of them all, steaming at 15-9/10 knots. This vessel has
3300 tons displacement, and is armed with five guns of eight tons and
five of three tons. None of the remaining eight exceed 2400 tons in
displacement, none exceed 15.3 knots in speed (but none are less than
14 knots), and each of them carries fifteen guns of three tons. Next
come thirteen second-class cruisers, ranging in displacement between
1540 and 2100 tons, and in speed between 11½ and 15 knots; they are
principally armed with 3-ton guns. There is another vessel, the
_Rapide_, in this class, but I only know of her that her tonnage is
1900 tons. Of cruisers of the third class there are fifteen, ranging
from 1000 to 1400 tons, and principally armed with 3-ton guns. Their
speeds vary from 10 to 13 knots; one, however, the _Hirondelle_,
steaming at 15½ knots. The French have likewise thirty-five vessels,
“avisos,” etc., of which about one-half are from 1400 to 1600 tons,
and the remainder are from 720 to 1000 tons. About six of them
reach or approach 13 knots, but most of them range between 10 and
11 knots, some of them falling as low as 8 knots. I have further to
make mention of two very fast vessels—for they are to steam 19½
knots—now under construction, named the _Surcoup_ and the _Forbin_,
each of 1850 tons, and each armed with two 3-ton guns. There is
also a vessel of 1540 tons, named the _Milan_, which steams 18
knots, and is armed with five very light (24-cwt.) guns. The French
navy possesses also ninety-nine vessels, most of them carrying guns
(many of 3 tons, some of 5 tons, and one or two of 8 tons), and also
twenty-eight steam transports, varying in size from 1200 to nearly
6000 tons, the largest of them, the _Nive_ (of 5680 tons), steaming
14 knots.
The navies of Europe, including the British navy, have undergone of
late considerable expansion in respect of their very fast unarmored
steel vessels, the designing and successful construction of which
have been brought about by improvements in the quality of ship
steel and in steam-machinery, notably as regards the latter, by the
employment of “forced draught.”[27] These are called torpedo-vessels,
as distinct from torpedo-boats. There are in process of completion
for the British navy eight of 1630 tons (the _Archer_ class), each
carrying six 6-inch 5-ton guns, and estimated to steam with forced
draught from 16 to 17 knots; two of 1430 tons each (_Scout_ class),
carrying four 5-inch 2-ton guns, with an estimated maximum speed
of 16 knots; and two of 785 tons (_Curlew_ class), called “gun and
torpedo” vessels; speed, 15 knots; armament, one 6-inch 89-cwt.
and three 5-inch 36-cwt. guns. There is also a class of “torpedo
gun-boats” (the official designation, but not one which expresses any
very manifest distinction from the last-named class), which are of
a very notable character. This (the _Grasshopper_) class, of which
each vessel is of only 450 tons displacement, is to be supplied
with engines of 2700 indicated horse-power. The diagrams on page 90
exhibit the general form and particulars of these very remarkable
little vessels, which are expected to steam at fully 19 knots (22
miles) per hour. Against the above torpedo-vessels of the British
navy are to be set, in the French navy, four torpedo-cruisers of
1280 tons, 17 knots speed, carrying each five 4-inch guns; and eight
torpedo despatch-vessels, each of 320 tons, and designed to steam at
18 knots, carrying machine guns only; such machine guns being also
carried, of course, by all the fast torpedo-vessels and gun-boats,
both French and English, previously referred to, but in their cases
in conjunction with their other guns. These 320-ton torpedo-vessels
of France are to be driven by machinery of 1800 indicated horse-power.

(SIDE VIEW).]
[Illustration: THE “GRASSHOPPER”—PLAN OF UPPER DECK, POOP, AND
FORECASTLE.]
It may be observed with regard to these small craft furnished with
such enormous steam-power (in proportion to their size and tonnage)
that there is much uncertainty as to the speeds which they will
attain. Not only are the builders without experience of similar
vessels by which to guide themselves, but where the proportion of
power to displacement is so great, slight differences both in hulls
and machinery, no less than in immersion and trim, may produce
unforeseen results. As designers who fail to realize promised speeds
are liable to be discredited, while those whose vessels surpass their
promised speeds may be unduly praised, it is but reasonable to expect
that the promised speeds will usually even be more than realized.
This has been the case with the _Bombe_, the first of the French
torpedo despatch-vessels which have been tried under steam, and
which, under the promise of 18 knots, realized no less than 19½ knots
on the measured mile. It should be added that all of these extremely
fast small craft in both navies are propelled by twin engines and
screws. As great public interest will be felt in the trials of these
very novel and special vessels—as mere steamers no less than as
war craft—it may be well to give their names, to facilitate their
identification hereafter.
ENGLISH TORPEDO GUN-BOATS: _Grasshopper_, _Rattlesnake_,
_Spider_, _Sandfly_—each having a displacement of 450 tons, 2700
horse-power, 200 feet length, 23 feet breadth, 8 feet draught, and
a speed estimated at 19 knots.
FRENCH TORPEDO DESPATCH-VESSELS: _Bombe_, _Couleuvrine_, _Dague_,
_Dragonne_, _Flèche_, _Lance_, _Saint-Barbe_, _Salve_—each having
a displacement of 320 tons, 1800 horse-power, 194.3 feet length,
21.4 feet breadth, 5.1 feet draught, and, with the exception of the
_Bombe_, a speed estimated at 18 knots. The actual speed of the
_Bombe_ is 19.5 knots.
Besides the above vessels, the two navies (English and French) are
provided as follows with torpedo-boats: The English have nine small
(56 feet long) and slow (14½ to 15 knots) of wood; fifty small
(60 to 66 feet long) and slow (15 to 16 knots) of steel; nineteen
others of greater length, but all less than 93 feet, and of speeds
varying from 16 to 19 knots; six of 100 to 113 feet, and 19 knots;
fifty-three of 125 feet in length, and 19 knots; and two building,
_viz._, one of 135 feet in length, and 22 knots, and one of 150
feet in length, and 20 knots; in all, one hundred and thirty-nine
torpedo-boats, of which the 135-feet boat carries four 3-pounder
quick-firing guns, and the 150-feet boat carries five 6-pounder guns
of that kind. The French have nine under 70 feet in length; forty-one
under 100 feet in length, steaming at 17 to 18 knots; eighteen of
108 feet in length, somewhat faster; nine of 113 feet in length,
steaming at 22 knots; and fifty-one of 114 feet in length, steaming
at 20 knots; in all, one hundred and twenty-eight torpedo-boats, all
armed with machine guns only. As the nine slow wooden boats of the
English navy can hardly be regarded as torpedo-boats at all, it may
be said that of torpedo-boats, built and building, the English have
one hundred and thirty, and the French one hundred and twenty-eight,
of which the English have seventy-nine completed, and fifty-one
building and completing, and the French have sixty-eight completed,
and sixty building and completing. The English navy is therefore
slightly, but only slightly, in advance of the French in the matter
of torpedo-boats proper, while in respect of extremely fast sea-going
torpedo-vessels of 320 and 450 tons respectively, the English have
three under construction and one completed, while the French have one
(the _Bombe_) completed and seven under construction.
NOTES.
Of the 150,000,000 francs appropriated in France this year for the
construction of war-ships nearly nine-tenths were set aside, not
for the building of large armored vessels, but for the following
fast cruisers and auxiliary classes: “Six cruisers, class I.,
30,000,000 francs; ten cruisers, class II., 26,000,000 francs; twenty
torpedo-catchers, 12,000,000 francs; fifty gun-boats, 15,000,000
francs; one hundred torpedo-boats, 25,000,000 francs; three
coast-defence vessels, 25,000,000 francs.”
Notwithstanding the late change in administration this seems to show
that the policy of Admiral Aube, referred to in the introductory
chapter, is still potent, and that the government believes the next
war with England will be carried on by French cruisers attacking
British commerce, and that sharp, destructive dashes will be made
against the enemy’s coast by ships with great speed, and such
sufficient power that “all of England’s littoral towns, fortified
and unfortified, whether purely peace establishments or warlike,”
will be burned or pitilessly ransomed. “In any future war,” continues
this exponent of the new ideas, “France will come down from the
heights of the cloudy sentimentality which has created that monstrous
association of words, _rights_ of war, and her attack on every source
of English riches will become not only legitimate but obligatory.”
It is certain that French naval activity is now mainly directed to
the construction of vessels just suited to these new theories. At
the same time she has a formidable fleet of heavily armored vessels,
a rough comparison with those of England being as follows, in the
classes which have over fifteen inches of armor protection and carry
guns above forty-three tons in weight:
Ships. Armor. No. Guns. Weight.
3 21½ inches 6 breech-loading rifles 75 tons.
5 20 ” 8 ” ” 75 ”
6 18 ” 8 ” ” 50 ”
2 15 ” 24 ” ” 48 ”

England has three ships with armor from twenty-four inches to
eighteen inches thick, and twelve ships with armor eighteen inches
thick; three ships carry six 110-ton guns, six carry twenty-four
67-ton guns, five carry sixteen 43-ton guns, all breech-loading
rifles, while one has four muzzle-loading 80-ton guns.
The latest additions to the armored fleet of France are the _Hoche_,
of the Marceau type of battle-ship, and the _Cocyte_ and _Mitraille_,
coast-defence gun-boats. The _Marceau_, launched May 24, 1887, is
built of steel with an under-water skin of iron; a double bottom
extends below the engines, boilers, and magazines, and the hold is
divided into thirty-one water-tight compartments by horizontal and
longitudinal bulkheads. The armor-belt encircles the ship, dips
forward to strengthen the ram, is carried twelve inches above the
load water-line, and varies in thickness from 13.7 to 17.7 inches;
the barbette towers are 15.7 inches thick, and the armored deck,
above which there are many compartments, is 2.6 inches thick. The
armament is made up of four 13-4/10-inch guns mounted in the towers,
of one 5½-inch gun at the bow, and of sixteen 5½-inch pieces in
broadside; the secondary battery includes twenty Hotchkiss guns and
four above-water torpedo tubes.
The estimated horse-power is 8548 (not 5500 as stated on page 76)
with natural draft, and 12,000 with forced draft, the estimated speed
being 16 knots, the coal capacity 800 tons, and the coal endurance
1500 miles at full power and 3500 miles at 11 knots speed. The
_Neptune_ and the _Hoche_, of the same general plans and dimensions,
were launched in the spring of this year. As originally designed
the _Hoche_ was expected to develop 16 knots and 7000 indicated
horse-power, but by the application of forced draft the speed was
increased to 17½ and the power to 12,000. The armament consists—not
of the four 52-ton guns given in the table on page 76—but, as stated
in the text, of two 13.4-inch guns (34 centimetre) mounted one in
each of the midship turrets, of two 10.6-inch guns (27 centimetre)
carried one in each of the waist turrets, and of eighteen 5.5-inch
guns (14 centimetre) so disposed in broadside within the unarmored
central superstructure which occupies the deck between the turrets
that the forward and after pairs are given bow and stern fire
respectively. The armor-belt is similar to that of the _Marceau_, but
the protective deck is from 3.15 to 3.54 inches thick, and the heavy
gun sites are protected by 15.75 inches of compound armor.
The _Amiral Courbet_ (formerly the _Foudroyant_) carries four
10.6-inch, six 5.5-inch, and twelve rapid-fire guns. She developed
6016 horse-power with natural and 8088 with forced draft, the mean
speed being 14.2 knots on a consumption of 2.35 pounds per power
each hour. The _Indomptable_, _Requin_, _Caïman_, and _Terrible_ are
sister battle-ships. They were originally laid down in 1877, and
the _Terrible_ was only completed ready for sea in 1887. They are
constructed like the _Marceau_, of iron and steel, the outer skin of
the under-water body being of the former metal; the compound armor
is from 13 to 19⅝ inches in thickness, and carries five feet of its
seven feet six inches width below the water-line. In each of two
pear-shaped barbette towers situated on the longitudinal midship
line, and protected by 17¾ inches of armor, a 16.5-inch gun, with
its axis twenty-one feet above the water is mounted; in addition
there are four 4-inch breech-loading rifles and a secondary battery
of rapid-fire guns and torpedo-tubes. The _Indomptable_, launched
in September, 1883, made in her trial trip in August, 1886, a speed
of 15 knots, and is officially rated as having a sea speed of
13.5 knots. All work upon the partially protected ships _Brennus_
and _Charles Martel_ was stopped in 1886, and their specific
appropriation has been transferred to the sum already assigned for
the construction of fast cruisers and torpedo-boats.
The _Cocyte_ and _Mitraille_ belong to a new class, or rather they
represent a type which, after disappearing for a season of doubt and
denial, has had its value so much recognized that three Continental
nations are giving it earnest study. A late French Minister of
Marine asked within a year for money to construct fifty of these
gun-boats, but was then refused the grant, a decision for which
Admiral Sir George Elliot thinks England ought to be very grateful.
This distinguished officer believes in the value of the type, and
hopes that the Admiralty “will take note of the threat thus made”
before the theory is allowed to prevail that adequate security can
be given to the British coasts by sea-going cruisers, submarine
mines, shore batteries, and torpedo-boats. The boats present a small
target, and give good armor protection to guns which, when the
vessels are inshore or reinforced by land batteries, have sufficient
power to keep battle-ships at a distance. They are very handy, have
good speed, and are economical, because for the same money they
can, as flotillas, bring into the action four times the gun-power
possible in the large battle-ships. In France this type is divided
into two classes—the _Achéron_, _Cocyte_, _Phlegéton_, and _Styx_,
of 1639 tons, belonging to the first, and the _Fusée_, _Grenade_,
_Mitraille_, and _Flamme_, of 1045 tons, to the second. The iron and
steel hulls are extensively subdivided into water-tight compartments,
and are protected by complete belts of steel armor at the water-line,
and by arched steel-armored decks. The superstructures above the
protective decks have water-line belts of cellulose. The armament
consists of one heavy gun mounted in a barbette tower, and of a
strong secondary battery of machine guns and torpedoes.
The most important contributions to the sea-going navy of France
are the cruisers. In the naval programme adopted after the war with
Germany, ships of high speed were decided to be of such great value
that thirty-four—sixteen of the first and eighteen of the second
class—were provided for. At the present day French naval policy
seems to pin its faith to fast cruisers, 5½-inch breech-loading guns,
and torpedo-vessels. In pursuance of this belief the _Tage_, the
largest unarmored cruiser yet designed by any nation, was laid down
in 1885; she is ship-rigged, has a complete under-water curved deck,
lightly armored bulkheads forward and abaft the battery, a steel
conning-tower, and heavily plated hatchways. A belt of cellulose
along the water-line, and the subdivision of the space above the
protective deck into water-tight compartments, will, it is claimed,
insure the safety of the ship in action. This employment of cellulose
to stop leaks automatically was very successfully demonstrated in
the experiments made at Toulon with a target “composed of fourteen
parts of cellulose and one part of cellulose in fibre, the whole
compressed into a felt-like mass, with a lining two feet thick. A
shot seven and one-half inches in calibre was fired against this
target at a distance to insure penetration. The result was not only
satisfactory but extraordinary. The shot, which carried away about
one-fifth of a cubic foot of the composition, had no sooner passed
through than the cellulose closed up so firmly that a strong man was
unable to insert his arm into the hole. A tank filled with water was
then hung against the place where the shot had entered, and after an
interval of fifteen minutes water began to trickle through, but not
more than a man with a bucket could easily intercept. As soon as the
composition became thoroughly soaked, it offered increased resistance
to the entrance of the water, which eventually ceased to flow, and
the breach was closed automatically. The results were the same where
shells were used instead of shot, and red-hot coals were heaped upon
the composition without causing its ignition.”[28]
The twin-screw cruiser _Cecile_, which was designed before the
_Tage_, and is somewhat smaller, illustrates the principle of
duality in construction; the two main engines are situated in
separate compartments, and the six boilers are arranged in three
different groups. The sail area is 2153 square yards, and the steel
lower masts serve as ventilators to the hold, and carry steel
crow’s-nests in which are mounted rapid fire and machine guns. The
primary batteries of the two ships are similar, each carrying six
6¼-inch guns on the spar-deck (one forward, one aft, and four on
sponsons) and ten 5½-inch pieces on the covered deck in broadside.
The secondary battery of the _Cecile_ consists of ten 37-millimetre
(1.45-inch) guns, and that of the _Tage_ of three 47-millimetre
(1.85-inch) rapid-fire guns, and twelve 37-millimetre revolving
cannon—all of the Hotchkiss pattern. Both ships are supplied with
above-water torpedo tubes, the former having four, the latter seven.
The estimated maximum speed of the _Tage_ is 19 knots, with 10,330
horse-power, and that of the _Cecile_ is 18½ knots, with 9600
horse-power. The latest cruisers laid down are the _Jean Bart_ and
the _Dupuy de Lôme_, the first bearing the name of the rugged old
sea-wolf who entered the navy as an apprentice and died a famous
admiral, and the other that of the constructor who designed both in
wood and iron the first steam line-of-battle ships. These vessels are
of 352 feet length, 43.6 feet beam, 18 feet 10 inches mean draught,
and 4162 tons displacement; their estimated maximum speed is 19
knots. The main battery is composed of four 6.3-inch guns mounted on
sponsons, and of six 5.5-inch carried in broadside, and the secondary
armament has six 37-millimetre revolving cannons, four 3-pounder
rapid-fire guns, and the usual torpedo tubes.
The _Alger_ and _Isly_ are similar in construction to the _Cecile_,
but have the dimensions and armament of the _Jean Bart_; they are
designed for 19 knots, and a coal endurance of 3600 miles at 13
knots. The _Mogador_ is a rapid cruiser of 4325 tons, and of nearly
similar design, armament, speed, and endurance as the above. The
_Chanzy_, _Davoust_, and _Suchet_ belong to the same class of
“croiseurs à barbette,” and are of 3027 tons displacement, with an
estimated speed of 20 knots.
The _Surcoup_ and _Forbin_ illustrate another favorite type of
cruiser. They are 311 feet 7 inches long, have 30 feet 6 inches
beam, and on a mean draught of 13 feet 11 inches displace 1848 tons.
The hull weighs 817 tons, and the engines (with boilers filled) 544
tons; the coal capacity is 200 tons, and the endurance 2400 miles at
10 knots. The engines are expected, with forced draft, to develop
6000 indicated horse-power and 19.5 knots. They have a four-masted
schooner rig, spread 7255.5 square feet of canvas, and carry a
complement of one hundred and fifty officers and men. The battery
consists of two 5.5-inch guns on the upper deck, three 47-millimetre
rapid-fire guns on the poop and forecastle, four 37-millimetre
Hotchkiss revolving cannon on the rail, and five torpedo launching
tubes—two firing ahead, one astern, and one on each beam. This
lightness of battery and small coal capacity indicate with great
precision how much weight-carrying power has been sacrificed to spars
and sails. The _Coetlogon_ and _Cosmao_ laid down this year are of
the same type.
Wishing to obtain a small class of steel cruisers, the French
government lately invited the leading ship-builders to send in
competitive designs for a vessel which at an extreme draught aft
of fourteen feet would on the least possible displacement sustain
with natural draft a speed of eighteen knots for twelve hours, and
with forced draft a speed of nineteen knots for two hours. The coal
endurance was to be 2400 miles at ten knots, the main battery to
include two 5.5-inch guns, and the protective steel deck to be 1.6
inch thick. Five competitors furnished plans, and finally those of
the Société de la Gironde were chosen, and the two vessels now known
as the _Troude_ and the _Lalande_ were laid down. Their principal
dimensions are, length 311 feet 7 inches, beam 31 feet, mean draught
14 feet, and displacement 1877 tons. The armament will be two
5.5-inch and three rapid-fire guns, four 37-millimetre revolving
cannon, and a supply of torpedo tubes. The vessels, as with the
_Surcoup_ type to which they are very similar, will have a fore and
aft rig and a complement of one hundred and sixty.
The _Duguesclin_, referred to on page 84, is an armored cruiser built
of steel and iron and sheathed with wood and coppered; an iron armor
belt 9⅛ to 6½ inches thick encircles her, and the four barbettes are
protected by 8 inches of compound armor. The armament consists of
four 9.45-inch guns in the barbettes, of one 7.5-inch gun in the bow,
and of six 5.5-inch pieces on broadside, in addition to two 6-pounder
rapid-fire guns, twelve revolving cannon, and two above-water torpedo
tubes. Her displacement is 5869 tons, draught 23 feet 3 inches, and
she has developed 4100 horse-power and 14 knots. The _Sfax_ is a
partially protected steel cruiser, which is sheathed with wood and
coppered, and has an under-water curved steel protective deck 1.5
inches thick. There is the usual water-tight subdivision below and
above this deck, together with the lately adopted cellulose belt. The
armament consists of six 6.3-inch guns, four mounted on sponsons,
with bow and stern fire, and two in recessed ports with bow and beam
fire; of ten 5.5-inch guns in broadside on the main deck, and of
eight Hotchkiss revolving cannon. In May, 1887,[29] “with natural
draft, the mean indicated horse-power developed for four hours was
4333, and the speed 15.9 knots. With forced draft the mean results
of a six hours’ trial were, indicated horse-power, 6034; revolutions,
78; mean speed, 16.84 knots. The trials for coal endurance showed
that with full natural draft speed the consumption was 1.96 pounds
per hour per indicated horse-power developed, and with forced draft
it was 2.10 pounds. During these trials the draught of water was 19
feet 4 inches forward and 25 feet 1 inch aft, which was in excess
of the normal designed draughts of 19 feet 8 inches and 24 feet 8
inches. Notwithstanding this fact, and the fact of the indicated
horse-power falling much below the estimated power of the engines
(5000 with natural, 7500 with forced draft), the speed realized
exceeded the maximum estimated of 16.5 knots.”
France has been very active in the construction of torpedo-vessels.
On the present plane to which the science of naval warfare has
advanced the great tactical question is whether torpedo-boats or
flotillas are, in high-sea duels or engagements, to take the place of
huge ships or large fleets. There are, even in France, very marked
differences of opinion upon this point, but so far as official policy
and programme can assert a belief, there is no other nation, Russia
alone excepted, which appears to hold the torpedo in such high
esteem. The manœuvres of 1886 were notable for the prominence given
to that type, and of the forty vessels assembled this year for drill
and instruction at Toulon, twenty-one were torpedo craft of some
kind. The French navy has over two hundred torpedo-boats, which vary
in length from seventy to one hundred and thirty-three feet, and in
speed from fifteen to twenty-three knots; England has one hundred
and eighty-one, of which eighty-eight are built and ninety-three
are under construction; these differ as much among themselves as
the French boats, their speed range being about the same, and their
lengths varying from sixty-three to one hundred and fifty feet.
Generally described torpedo-boats may be divided into two classes,
the first including such as are of a size to keep the sea and act
independently, and the second those carried by ships. The Whitehead
torpedoes, the type most generally used, are ejected from their
firing tubes by various means, slow burning powder being employed
in some cases, though more frequently compressed air or steam. The
success of the French boats in China has revived the use of the spar
torpedo in combination with the locomotive type, and with us the
promised success of the Howell design may cause another revolution in
this system of attack.
“Boats exceeding one hundred feet in length,” writes White, “have
been shown capable of making long sea-voyages unaccompanied, and
the fact has been seized upon by enthusiasts in torpedo warfare
like the late Gabriel Charmes as evidence that the days of the
armored ship, of the large and costly cruiser, were numbered. Actual
experience is not favorable to this extreme view. There is a clear
and marked distinction between the capability of making long sea
passages in safety, when specially prepared for the purpose, and the
sure sea-going qualities of large ships. Boats of the largest size
and small swift vessels cannot equal large vessels in the power of
maintaining their speed and fighting efficiency or rough war. Life
is scarcely endurable for long periods in these overturning boats
and small craft, cooking is often a difficulty, and it is not every
officer who can rival the foreign commander of a torpedo-boat I
once met, who had acquired the power of living for long periods on
sherry and eggs. M. Weyl stated a fact when he said of the grand
manœuvres with the French iron-clads and torpedo flotilla last year
(1886), ‘In my experience as a sailor I have always found that the
sea is merciful to big ships and hard upon small ones.’ A moderately
rough sea that scarcely troubles the iron-clad or the cruiser of
considerable size, suffices to render inevitable a reduction in speed
of the small vessels, and a serious loss of power in the accurate
use of their torpedoes and guns. As adjuncts to fleets, the small
swift vessels and boats are undoubtedly of immense value under many
circumstances; for the defence or attack of forts and coasts they
are well fitted, but as substitutes for all other types, and as the
successful rival of large war-ships in sea service, their claim is
not, and probably will not be, established.
“The discovery of the minimum size of swift torpedo-vessels or
torpedo-boat destroyers really capable of independent sea service
with a fleet is now engaging attention in all navies. In France the
first attempts were made in the _Bombe_ class in 1883; some vessels
of this class were tried in the recent manœuvres and favorably
mentioned. In England the _Grasshopper_ class was designated in
1885, and the first completed vessel, the _Rattlesnake_, is now
completing her speed trials.” Since this last sentence was written
the _Rattlesnake_ has made 18.799 knots with a collective indicated
horse-power of 2718.27, and though the weather was boisterous,
proved that under normal conditions she could furnish a fairly
steady platform for her battery. Chief Constructor White continues
as follows: “These vessels are of 450 tons, and estimated to steam
about 19 knots an hour. Messrs. Thomson, of Clydebank, have just
completed another example of the class, intermediate in size between
the _Bombe_ and _Grasshopper_, and said to have attained the very
high speed of 22½ knots on trial in smooth water. Experience at sea
with these vessels will be of immense value to future designs. They
combine an armament of light guns with torpedo armaments, and can
act either as torpedo-vessels or as destroyers of torpedo craft.
Similarly in the largest classes of torpedo-boats light guns as well
as torpedoes are provided for. In fact there has been a departure
from the original idea of having the torpedo as the only weapon, as
the boats have increased in size, and this change cannot but commend
itself.”
The _Milan_ mentioned in the text was designed in 1879 for a torpedo
despatch-vessel, but is now used as a scout. She is 303 feet in
length, 32 feet 10 inches in beam, draws 15 feet 1 inch aft, and
has a displacement of 1550 tons. She carries a fair battery but no
torpedoes, is propelled by twin screws, each worked by two compound
tandem engines, and has Belleville boilers. On her trial she made
18.4 knots in a rough sea, and developed with natural draft 4132
horse-power, or more than was expected with forced draft; she carries
three hundred tons of coal and has a three-masted schooner rig.
The rapid development of torpedo-vessels since her day has resulted
in the evolution of different types suited to different demands,
and of late France has adopted the following classification for her
torpedo flotilla:
