Probably Lord Fisher was the first seaman holding high position to actually warn the British Government of the likelihood of Germany’s illegitimate use of the submarine. Early in 1914 he handed to Mr Asquith and the First Lord of the Admiralty a memorandum pointing out, among other things, that the enemy would use underwater boats against our commerce.[[2]] His prescience was forestalled thirteen years before by Commander Sir Trevor Dawson, who had prophesied that the enemy would attack our merchant fleet in much the same way as the Boers were then attacking the army in the Transvaal. “Submarine boats,” he told a meeting of engineers, “have sufficient speed and radius of action to place themselves in the trade routes before the darkness gives place to day, and they would be capable of doing almost incalculable destruction against unsuspecting and defenceless victims.”

Originally Germany was by no means enamoured of the new craft. Her first two submarines did not appear until 1905–6; Great Britain’s initial venture was launched at Barrow-in-Furness in 1901. The latter, the first of a batch of five, was ordered on the advice of Lord Goschen. Even then the official attitude was sceptical, not altogether without reason. Mr H. O. Arnold-Forster, speaking in the House of Commons on the 18th March, 1901, after admitting that “there is no disguising the fact that if you can add speed to the other qualities of the submarine boat, it might in certain circumstances become a very formidable vessel,” adopted what one might call a misery-loves-company attitude. “We are comforted,” he averred, “by the judgment of the United States and Germany, which is hostile to these inventions, which I confess I desire shall never prosper.”

Dr Flamm, Professor of Ship Construction at the Technical High School at Charlottenburg, who should and probably does know better, has aided and abetted certain other publicists in foisting on the public of the Fatherland the presumption that the submarine is a German invention. This is not the place for a full history of the underwater craft from its early to its latest stages, but perhaps it is permissible to give a few particulars regarding the toilsome growth of this most formidable type of vessel.

The first underwater craft of which there is anything approaching authentic record was the invention of Cornelius Drebbel, a Dutchman who forsook his own country for England. According to one C. van der Woude, writing in 1645, Drebbel rowed in his submerged boat from Westminster to Greenwich. Legend or truth has it that this “Famous Mechanician and Chymist” managed to keep the air more or less sweet in his craft by means of a secret “Chymical liquor,” and that the structure was covered with skin of some kind to make it watertight. Drebbel, who also professed to have discovered the secret of perpetual motion, is stated to have hit upon the idea of his invention by the simple process of keeping his eyes open. He noticed some fishermen towing behind their smacks a number of baskets heavily laden with their staple commodity. When the ropes were not taut the vessels naturally rose a little in the water. He came to the conclusion that a boat could be weighted in much the same way to remain entirely below the surface, and propelled by means similar to a rowing-boat. It is even said that King James travelled at a depth of from twelve to fifteen feet in one of the two vessels constructed by Drebbel, whose invention is referred to in Ben Jonson’s Staple of News.

The submarine may be said to have remained in this essentially elementary stage until 1775, when David Bushnell, an American, launched a little one-man submarine after five years of planning and preparation. The shape of the vessel resembled a walnut held upright, the torpedo being carried outside near the top. At the bottom was an aperture fitted with a valve for admitting water, while a couple of pumps were provided for ejecting it. About 200 lb. of lead served as ballast, which could be lowered by ropes for the purpose of giving immediate increase of buoyancy should emergency require it. “When the skilful operator had obtained an equilibrium,” Bushnell writes, “he could row upward and downward, or continue at any particular depth, with an oar placed near the top of the vessel, formed upon the principle of the screw, the axis of the oar entering the vessel; by turning the oar one way he raised the vessel, by turning it the other way he depressed it.” A similar apparatus, worked by hand or foot, whichever was the more convenient, propelled the submarine forward or backward. The rudder could also be utilized as a paddle.

Bushnell provided his little wooden craft with what he called a crown and we should designate a conning-tower. In this there were several glass windows. Neither artificial light nor means of freshening the air was carried, though the submarine could remain submerged for thirty minutes before the condition of the atmosphere made it necessary to ascend sufficiently near the surface to enable the two ventilator pipes to be brought into action. The water-gauge and compass were rendered discernible by means of phosphorus.

The torpedo—Bushnell termed it a magazine—was an oak box containing 150 lb. of gunpowder and a clockwork apparatus which was set in operation immediately the affair was unshipped. It was attached to a wooden screw carried in a tube in the brim of the ‘crown.’ Having arrived beneath an enemy vessel, the screw was fixed in the victim’s hull from within the submarine, and the ‘U-boat’ made off. At the time required the mechanism fired what to all intents and purposes was a gun-lock, and the torpedo blew up.

The wooden screw was the least successful of the various appliances. An attempt was made in 1776 to annihilate H.M.S. Eagle, then lying off Governor’s Island, New York. The operator apparently tried to drive his screw into iron, and quite naturally failed. Writing to Thomas Jefferson on the subject, Bushnell suggests that had the operator shifted the submarine a few inches he could have carried out his operation, even though the bottom was covered with copper. Two other unsuccessful trials were made in the Hudson River. Owing to ill-health and lack of means, the inventor then abandoned his submarine, though in the following year he attempted to ‘discharge’ one of his magazines from a whaleboat, the object of attack being H.M.S. Cerberus. It failed to reach the British frigate, and blew up a prize schooner anchored astern of her. Washington was fully alive to the possibilities of Bushnell’s invention, but was evidently of opinion that it was too crude to warrant his serious attention. Writing to Jefferson, he says: “I thought, and still think, that it was an effort of genius, but that too many things were necessary to be combined to expect much from the issue against an enemy who are always upon guard.” Incidentally this was a remarkable testimonial to the men on look-out duty on the British vessels. Keen sight is still a recognized weapon against submarine attack.

In 1797 Robert Fulton, also an American, brought his fertile brain to bear on the submarine, possibly on hearing or reading of David Bushnell’s boat. One would have anticipated that the era of the Revolutionary and Napoleonic wars would be propitious for the introduction of new plans and methods calculated to bring a seemingly never-ending state of hostilities to an end. Novel propositions were certainly brought forward; few were utilized. Fulton, an artist by profession, simply bubbled over with ideas connected with maritime operations. Moreover, he had extraordinary tenacity and enthusiasm. Set-backs seemed to give him added momentum. He tried to do business with Napoleon in France, with Pitt in England, with Schimmelpenninck on behalf of Holland, not always without success, before returning to the United States and running the steamer Clermont at five miles an hour on the Hudson.

At the end of 1797 the enterprising American proposed to the French Directory to construct a submarine, to be christened the Nautilus, or, as he frequently spelled it, the Nautulus. So great was his faith in the project for “A Machine which flatters me with much hope of being Able to Annihilate” the British Navy, that he was willing to be remunerated by results, viz., 4000 francs per gun for every ship of forty guns and upward that he destroyed, and half that amount per gun for smaller vessels. All captures were to become the property of “the Nautulus Company.” A little chary of being caught red-handed by the enemy and dealt with as a pirate, he asked that he might be given a commission in the Service, which would ensure for him and his crew the treatment of belligerents. Pléville le Pelley, Minister of Marine, deeming that such warfare was “atrocious,” and yet not altogether unkindly disposed toward it, refused the latter request, which would obviously give the submarine official sanction. The proposed payment by results he reduced by fifty per cent. All the arrangements were subsequently cancelled.
