Chapter II: Introduction: BY

ADMIRAL THE HON. SIR E. R. FREMANTLE, G.C.B, C.M.G.

(_Rear-Admiral of the United Kingdom._)

The natural attitude of the Naval mind towards submarines is the same now as that expressed by Lord St. Vincent when Fulton invented the notorious “catamaran” expedition.

Fulton had been trying some experiments before Pitt, who favoured the project, to which Lord St. Vincent, then First Lord of the Admiralty, was strongly opposed, and he bluntly stated that “Pitt was the greatest fool that ever existed to encourage a mode of war which those who commanded the seas did not want, and which, if successful, would deprive them of it.”

It was, our Admiralty recently held, “the weapon of the weaker power, and not our concern,” then we were to “watch and wait,” which sounded plausible but was evidently dangerous, and as the success of the French submarines became too evident we were forced to follow suit. As Lord Selborne reminded us when speaking about the boilers, we have too often ignored new inventions and resisted change till we were left well behind in the race, as we were with ironclads, breech-loading guns, and other improvements in naval warfare.

The fact is that every new invention has its infancy of weakness and failure, its adolescence of partial adoption, and doubtful success, and its manhood of completion and achievement. Unfortunately the natural conservatism of a profession and perhaps of human nature is apt to deride the early failures, and to prejudice the invention so as to delay its adoption. Every inventor can tell stories of the obstruction he has met with, and often of his ultimate triumph, like Mr. Whitworth and his steam hammer pile-driving competition, when he succeeded in driving piles with his steam hammer in as many minutes as it took hours under the method previously adopted, much to the astonishment of the old hands.

Certainly the submarine has had its period of failure and ridicule, for the attempt to use submarines dates from very ancient days, as Mr. Fyfe’s interesting historical _résumé_ shows, yet it is only now arriving at the stage of development which forces us to reckon with it as a serious factor in naval warfare.

We need not follow Mr. Fyfe in his early history of the submarine, but leaving James I.’s somewhat apocryphal voyage under the waters of the Thames, the inventions of Bushnell, Fulton, Warner, and others, we may come to the Confederate diving boat during the war of secession. Here we have a real diving boat which, though it drowned three crews, did succeed in destroying the United States sloop _Housatonic_, one of the blockading fleet off Charleston, though she was herself sunk in the effort, drowning her fourth crew. It is interesting to compare this submarine boat with one of our modern _Hollands_.

The following is the description given by Captain Maury, the well-known hydrographer, then at the head of the Confederate torpedo bureau, of this unfortunate craft, or _David_ as she was called. “It was built of boiler iron, about 35 feet long, and was manned by a crew of nine men, eight of whom worked the propeller by hand, the ninth steered the boat and regulated her movements below the surface of the water. She could be submerged at pleasure to any desired depth, or could be propelled on the surface. In smooth, still water she could be exactly controlled, and her speed was about 4 knots.”

It is further stated that she could remain submerged for half an hour “without inconvenience to her crew,” and in action she was to drag a torpedo under a ship’s bottom, which was intended to explode on striking.

Now contrast this rude and dangerous craft with the “Holland” boats now building for the British Government, and the advance which has been made in the last forty years is evident.

I need not describe the _Holland_ here, but motive power, speed, radius of action, and torpedo are all essentially different; but above all it has been proved that a modern submersible boat like the French _Gustave Zédé_, or _Narval_, or our _Holland_ can remain under water truly “without inconvenience to her crew” for periods of nine or ten hours, so that all the problems connected with submarine navigation may be said to have been solved, except that of seeing under water, for when submerged the submarine is in cimmerian darkness, and more helpless than an ordinary vessel in the densest of fogs. Nor is it likely that invention has said its last word in regard to the submarine now that it is acknowledged to be a weapon of practical value.

On this point it is convenient to call to mind the remarkable development of the Whitehead torpedo since it was first adopted in our Navy rather more than thirty years ago. It happens that I have been able to refer to an article on torpedoes which I wrote in _Fraser’s Magazine_ just thirty years ago, in which I described the Whitehead of that day as having a speed of from 7 to 7½ knots, a range of 1,000 yards, and a charge of 67 lbs. of gun-cotton. Now, the speed of our modern Whiteheads is 30 knots, the range 2,000 yards, the charge 200 lbs. of gun-cotton, and, thanks to the gyroscope, it can be discharged with extraordinary accuracy.

Admitting, then, that the submarine is with us, and that it will remain, let us see what is likely to be its function in war. The submarine compares naturally with the torpedo destroyer or torpedo boat; like them it will attack by stealth, and it has neither their speed nor radius of action. But, whereas searchlights and quick-firing guns are effective weapons against the latter, they are of little use against the submarine, and as all these craft are to act by surprise, the advantage is strongly in favour of the submarine, which can approach with little danger of being discovered, with the cupola only showing, until close to her enemy, thus rendering a close blockade by large vessels impossible.

I have said that is naturally the weapon of the weaker power, but that it can be used and that it will be used by the stronger power acting on the offensive I see no reason to doubt. It can certainly be employed against ships at anchor unless they are suitably protected, and it can probably render good service in removing obstructions and clearing passages defended by torpedoes.

The question remains as to whether any antidote to the submarine is likely to be effective. It is possible that one may be discovered, but it is not easy to see in what direction we are to look for it, as the submarine differs from other craft in the fact that the possession of any number of similar vessels, by ourselves for instance, affords little or no protection against a few well-handled _Gustave Zédé’s_ in the hands of our enemies. At the same time they would be of little or no value against torpedo boats or destroyers; and cruisers blockading, moving about at a speed of 10 knots or more, at some distance from a port known to harbour submarines, would have little to fear, as it could only be by a lucky chance that a submarine could approach near enough to them to have a fair shot. It is also worthy of remark that the navigation and pilotage of a submarine, even with her cupola above water, would be by no means easy in shallow water or thick weather, and of the value of the periscope I cannot but feel somewhat sceptical. The French are stated to have found that submarines can be easily discovered from balloons; but this must naturally apply only to daylight and fine weather, and their opportunity will naturally occur in thick weather or at night.

I have offered these remarks to show that though I consider the submarine to be an important weapon, it clearly has its limitations, and I suspect that when we have them fairly under trial we shall find that when these are fully appreciated and the position of the submarine in naval warfare is duly assigned, much of the terror and mystery now surrounding this novel weapon will be removed. Probably it will be found to be a more dangerous and effective torpedo boat, and will supplant it in great measure.

Mr. Fyfe has done good service in giving us this popular account of submarines, which is a valuable addition to the scanty literature of the subject in the English language.

THE PROBABLE FUTURE OF SUBMARINE BOAT CONSTRUCTION.

BY

SIR EDWARD J. REED, K.C.B., F.R.S., M.P.

(_Chief Constructor of the Navy 1863–70._)

There is nothing in the nature of things that I know of to prevent submarine warfare being carried on in the future to a very large extent. This development will probably follow triple lines: (1) Vessels for the defence of ports and harbours, with sufficient means of proceeding outside to give the defence a certain limited power of attack in the approaches; (2) Vessels primarily designed for attack, and therefore capable of proceeding to sea for considerable distances; and (3) Smaller vessels to be taken to sea in ships, as part of their equipment, and capable of being lowered to take part in a battle, and raised again, and re-stowed on board when no longer needed in action. All these types of vessel will need to be endowed with the power of passing easily and quickly from the floating to the submerged condition, and back again to the surface when necessary; but the boats of the second class in the foregoing category will doubtless be developed to an extent as yet anticipated by very few of us, in respect alike of their ability to proceed for great distances below water, and of their ability to steam satisfactorily afloat when submergence is needless.

All who are acquainted with the structure of waves, so to speak, will be aware that wave disturbance diminishes very rapidly as we go down below the surface, and will consequently understand that when once we have succeeded in giving submarines a great range of under-water travel, we shall have endowed them with the capability of avoiding at pleasure in bad weather the tempestuous surface of the sea, with all the drawbacks to speed which stormy seas impose upon ships, and especially upon comparatively small vessels. In order to bring about this advantage, science has to effect, no doubt, immense improvements in the production of storage of air, or of its equivalent; but there is great reason to believe that the demand will bring the supply, as in so many other matters. Nor must it be forgotten that this is a branch of science for the development of which the ship proper, as we have hitherto known it, has offered few, if any, inducements. I do not know how the sight of an ordinary modern ship of war strikes the eyes of others, but for my part I never look at one, with its vast and monstrous assemblage of gaping mouths of funnels, pipes, and cowls, without thinking that our method of supplying breathing gas to men below in a ship is at present of a very elementary and unsatisfactory character. It is certainly the roughest and readiest method that could well be adopted. Nor is it without a sense of satisfaction that one knows that the submarine ship will at least sweep away these ugly and towering excrescences, and force us to resort much more than at present to the chemical and mechanical arts for the ventilation of vessels.

The development of the sea-going submarine will bring with it, doubtless, many improvements in the vessels which have been first mentioned, viz., vessels for the defence of ports and their approaches. It is not possible yet to say to what extent the “Holland” boats building at Barrow will prove fairly satisfactory, although my acquaintance with this class of vessel for several years past has given me a favourable impression of it—favourable, that is, as furnishing many elements of initial success. More than this could not be reasonably expected; nor can we doubt that with the skill of both the Admiralty designers and those of the great manufacturing establishment which has produced the first few vessels concentrated upon this class of boat, immense improvements may be confidently anticipated.

Of the third class of vessels before referred to the Goubet boat may be regarded as a commencing type. The principle of this boat appears to be that of carrying and launching torpedoes from external supports, the size and buoyancy of the vessels being very small by comparison with those of vessels which carry their torpedoes inside. M. Goubet appears to go beyond this principle, and to have other ideas, which are mentioned in the text of this work. Suffice it here to say that the idea of relieving the submarine boat from the necessity of carrying its torpedoes with it, goes a long way towards furthering the use of submarine torpedo craft carried on the decks, or at the davits of battleships and cruisers.

If one may contrast for a moment the present attempts at aerial navigation with the concurrent attempts at submarine navigation, one quickly sees how terribly the æronaut is handicapped as compared with the under-water sailor. The advantage of the dense medium which the sea offers to the submarine navigator is precisely the same as it has offered from the beginning of time to the surface navigator, and nothing new is needed to sustain the submarine ship, whereas the unhappy man who seeks to navigate the air has to obtain from a medium of extraordinary levity the support necessary for keeping him aloft. The difference between the specific gravity of air (of which ships are full) and of water is so great by comparison between the specific gravity of any gas available for filling aerial-ships and that of air, that the problem of the submarinist is easy indeed compared with the other. But it is in the face of this initial and enormous difficulty that the æronauts of to-day have apparently persuaded themselves that they can successfully float their balloon-ship in mid-air, and propel it not only against the rapid tides of the air in which it floats, but also drive it at a good additional speed. When men are to be found capable of committing their fortunes, and even their lives, to navigation of this kind, it is not surprising to find that the far easier problem of navigating the seas beneath the surface has won the attention and the effort of enterprising men. They certainly have chosen, if the humbler, also the more practical and promising field of operation. I doubt not that they have likewise chosen the more fruitful field.

It is worthy of remark that it is once again in connection with the arts of war that a great extension of human progress has been commenced. But for the temptation of gaining equality with, and even mastery over, our possible foes, the art of submarine navigation would certainly not have been attracting the attention of some of our best and most scientific men, who are once again eagerly developing—

“Those dire implements
Which sombre science with unpitying pains,
That love of neither man nor God restrains,
To warring foes presents.”

One can only be thankful that the world is so constituted and so ruled, that out of seeming evil often comes great good to men.

I have not been asked to say anything of the book with which these lines are associated. I may nevertheless remark that I have had an opportunity of hastily looking through the author’s proofsheets, and have formed the opinion that it is a most timely and highly instructive work, and one which gives to the non-technical world an extremely good review of all that has been done in the way of submarine war vessels, while the technical man into whose hands it may come will be compelled, by its great interest and by its clever record of facts, to read every page of it.
