THE COMING OF STEAM AND ELECTRICITY

In the fall of 1863, the Federal fleet was blockading the harbour of Charleston, S. C. Included among the many ships was one of the marvels of that period, the United States battleship Ironsides. Armour-plated and possessing what was then considered a wonderful equipment of high calibred guns and a remarkably trained crew, she was the terror of the Confederates. None of their ships could hope to compete with her and the land batteries of the Southern harbour were powerless to reach her.

During the night of October 5, 1863, the officer of the watch on board the Ironsides, Ensign Howard, suddenly observed a small object looking somewhat like a pleasure boat, floating close to his own ship. Before Ensign Howard's order to fire at it could be executed, the Ironsides was shaken from bow to stern, an immense column of water was thrown up and flooded her deck and engine room, and Ensign Howard fell, mortally wounded. The little floating object was responsible for all this. It was a Confederate submersible boat, only fifty feet long and nine feet in diameter, carrying a fifteen-foot spar-torpedo. She had been named David and the Confederate authorities hoped to do away by means of her with the Goliaths of the Federal navy. Manned only by five men, under the command of Lieutenant W. T. Glassel, driven by a small engine and propeller, she had managed to come up unobserved within striking distance of the big battleship.

The attack, however, was unsuccessful. The Ironsides was undamaged. On the other hand the plucky little David had been disabled to such an extent that her crew had to abandon her and take to the water, allowing their boat to drift without motive power. Four of them were later picked up. According to an account in Barnes, Torpedoes and Torpedo Warfare, the engineer, after having been in the water for some time, found himself near her and succeeded in getting on board. He relighted her fires and navigated his little boat safely back to Charleston. There she remained, making occasional unsuccessful sallies against the Federal fleet, and when Charleston was finally occupied by the Federal forces, she was found there.

In spite of this failure the Confederates continued their attempts to break the blockade of their most important port by submarine devices. A new and somewhat improved David was ordered and built at another port. News of this somehow reached the Federal Navy Department and was immediately communicated to Vice-Admiral Dahlgren, in command of the blockading fleet. Despite this warning and instructions to all the officers of the fleet, the second David succeeded in crossing Charleston bar.

 This new boat was a real diving submarine boat and though frequently called David had been christened the Hundley. It had been built in the shipyards of McClintock & Hundley at Mobile, Alabama, and had been brought to Charleston by rail. On her trial she proved very clumsy and difficult to manage. For her first trip a crew of nine men volunteered. Not having any conning tower it was necessary that one of the hatchways should be left open while the boat travelled on the surface so that the steersman could find his bearings. While she was on her first trip, the swell from a passing boat engulfed her. Before the hatchway could be closed, she filled with water. Of course, she sank like a piece of lead and her entire crew, with the exception of the steersman, was drowned.

In spite of this mishap the Hundley was raised and again put in commission. Lieutenant Payne who had steered her on her first fatal trip had lost neither his courage nor faith and again assumed command of her. Soon after she started on her second trip a sudden squall arose. Before the hatchways could be closed, she again filled with water and sank, drowning all of her crew with the exception of Lieutenant Payne and two of his men.

Undaunted he took her out on a third trip after she had again been raised. Ill luck still pursued her. Off Fort Sumter she was capsized and this time four of her crew were drowned.

The difficulties encountered in sailing the Hundley on the surface of the water apparently made no difference when it came to finding new crews for her. By this time, however, the powers that be had become anxious that their submarine boat should accomplish something against an enemy, instead of drowning only her own men and it was decided to use her on the next trip in a submerged state. Again Lieutenant Payne was entrusted with her guidance. Her hatches were closed, her water tanks filled, and she was off for her first dive. Something went wrong however; either too much water had been put in her tanks or else the steering gear refused to work. At any rate she hit the muddy bottom with such force that her nose became deeply imbedded and before she could work herself free her entire crew of eight was suffocated. Lieutenant Payne himself lost his life which he had risked so valiantly and frequently before.

Once more she was raised and once more volunteers rushed to man her. On the fifth trip, however, the Hundley, while travelling underwater, became entangled in the anchor chains of a boat she passed and was held fast so long that her crew of nine were dead when she was finally disentangled and raised.

Thirty-five lives had so far been lost without any actual results having been accomplished. In spite of this a new crew was found. Her commander, Lieutenant Dixon, was ordered to make an attack against the Federal fleet immediately, using, however, the boat as a submersible instead of a submarine.

Admiral David Porter in his Naval History of the Civil War described the attack, which was directed against the U. S. S. Housatonic, one of the newest Federal battleships, as follows:

At about 8.45 P. M., the officer of the deck on board the unfortunate vessel discovered something about one hundred yards away, moving along the water. It came directly towards the ship, and within two minutes of the time it was first sighted was alongside. The cable was slipped, the engines backed, and all hands called to quarters. But it was too late—the torpedo struck the Housatonic just forward of the mainmast, on the starboard side, on a line with the magazine. The man who steered her (the Hundley) knew where the vital spots of the steamer were and he did his work well. When the explosion took place the ship trembled all over as if by the shock of an earthquake, and seemed to be lifted out of the water, and then sank stern foremost, heeling to port as she went down. 

Only a part of the Housatonic's complement was saved. Of the Hundley no trace was discovered and she was believed to have escaped. Three years later, however, divers who had been sent down to examine the hull of the Housatonic found the little submarine stuck in the hole made by her attack on the larger ship and inside of her the bodies of her entire crew.

The submarines and near-submarines built in the United States during the Civil War were remarkable rather for what they actually accomplished than for what they contributed towards the development of submarine boats. Perhaps the greatest service which they rendered in the latter direction was that they proved to the satisfaction of many scientific men that submarine boats really held vast possibilities as instruments of naval warfare.

France still retained its lead in furnishing new submarine projects. One of these put forward in 1861 by Olivier Riou deserves mention because it provided for two boats, one driven by steam and one by electricity. Both of these submarines were built, but inasmuch as nothing is known of the result of their trials, it is safe to conclude that neither of them proved of any practical value.

Two years later, in 1863, two other Frenchmen, Captain Bourgeois and M. Brun, built at Rochefort a submarine 146 feet long and 12 feet in diameter which they called the Plongeur. They fitted it with a compressed-air engine of eighty horse-power. Extensive trials were made with this boat but resulted only in the discovery that, though it was possible to sink or rise with a boat of this type without great difficulty, it was impossible to keep her at an even keel for any length of time.

During the next few years, undoubtedly as a result of the submarine activities during the Civil War, a number of projects were put forward in the United States, none of which, however, turned out successfully. One of them, for which a man by the name of Halstead was responsible, was a submarine built for the United States Navy in 1865. It was not tried out until 1872 and it was not even successful in living up to its wonderful name, The Intelligent Whale. Its first trial almost resulted in loss of life and was never repeated. In spite of this, however, the boat was preserved and may still be seen at the Brooklyn Navy Yard.

In the meantime, an invention had been made by an Austrian artillery officer which before long was to exert a powerful influence on submarine development, though it was in no sense a submarine boat. The manner in which the submarines had attacked their opponents during the Civil War suggested to him the need of improvements in this direction. As a result he conceived a small launch which was to carry the explosive without any navigators. Before he could carry his plans very far he died. A brother officer in the navy continued his work and finally interested the manager of an English engineering firm located at Fiume, Mr. Whitehead. The result of the collaboration of these two men was the Whitehead torpedo. A series of experiments led to the construction of what was first called a "Submarine Locomotive" torpedo, which not only contained a sufficient quantity of explosives to destroy large boats, but was also enabled by mechanical means to propel itself and keep on its course after having been fired. The Austrian Government was the first one to adopt this new weapon. Whitehead, however, refused to grant a monopoly to the Austrians and in 1870 he sold his manufacturing rights and secret processes to the British Government for a consideration of $45,000.

Before very long, special boats were built for the purpose of carrying and firing these torpedoes and gradually every great power developed a separate torpedo flotilla. Hand in hand with this development a large number of improvements were made on the original torpedo and some of these devices proved of great usefulness in the development of submarine boats.

The public interest in submarines grew rapidly at this time. Every man who was a boy in 1873, or who had the spirit of boyhood in him then,—or perhaps now,—will remember the extraordinary piece of literary and imaginative prophecy achieved by Jules Verne in his novel Twenty Thousand Leagues Under the Sea. Little about the Nautilus that held all readers entranced throughout his story is lacking in the submarines of to-day except indeed its extreme comfort, even luxury. With those qualities our submarine navigators have to dispense. But the electric light, as we know it, was unknown in Verne's time yet he installed it in the boat of his fancy. Our modern internal-combustion engines were barely dreamed of, yet they drove his boat. His fancy even enabled him to foresee one of the most amazing features of the Lake boat of to-day, namely the compressed air chamber which opened to the sea still holds the water back, and enables the submarine navigator clad in a diver's suit to step into the wall of water and prosecute his labors on the bed of the ocean. Jules Verne even foresaw the callous and inhuman character of the men who command the German submarines to-day. His Captain Nemo had taken a vow of hate against the world and relentlessly drove the prow of his steel boat into the hulls of crowded passenger ships, finding his greatest joy in sinking slowly beside them with the bright glare of his submarine electric lights turned full upon the hapless women and children over whose sufferings he gloated as they sank. The man who sank the Lusitania could do no more.

More and more determined became the attempts to build submarine boats that could sink and rise easily, navigate safely and quickly, and sustain human beings under the surface of the water for a considerable length of time. Steam, compressed air, and electricity were called upon to do their share in accomplishing this desired result. Engineers in every part of the world began to interest themselves in the submarine problem and as a result submarine boats in numbers were either projected or built between 1875 and 1900.

One of the most persistent workers in this period was a well-known Swedish inventor, Nordenfeldt, who had established for himself a reputation by inventing a gun which even to-day has lost nothing of its fame. In 1881 he became interested in the work which had been done by an English clergyman named Garret. The latter had built a submarine boat which he called the Resurgam (I shall rise)—thus neatly combining a sacred promise with a profane purpose. In 1879 another boat was built by him driven by a steam engine. Nordenfeldt used the fundamental ideas upon which these two boats were based, added to them some improvements of his own as well as some devices which had been used by Bushnell, and finally launched in 1886 his first submarine boat. The government of Greece bought it after some successful trials. Not to be outdone, Greece's old rival, Turkey, immediately ordered two boats for her own navy. Both of these were much larger than the Greek boat and by 1887 they had reached Constantinople in sections where they were to be put together. Only one of them, however, was ever completed. Characteristic Turkish delay intervened. The most typical feature of this boat was the fact that it carried a torpedo tube for Whitehead torpedoes. On the surface of the water this boat proved very efficient, but as an underwater boat it was a dismal failure. More than in any other craft that had ever been built and accepted, the lack of stability was a cause of trouble in the Nordenfeldt II. As soon as any member of the crew moved from one part of the boat to another, she would dip in the direction in which he was moving, and everybody, who could not in time take hold of some part of the boat, came sliding and rolling in the same direction. When finally such a tangle was straightened out, only a few minutes elapsed before somebody else, moving a few steps, would bring about the same deplorable state of affairs. The Nordenfeldt II. acted more like a bucking bronco than a self-respecting submarine boat and as a result it became impossible to find a crew willing to risk their lives in manning her. Before very long she had rusted and rotted to pieces. In spite of this lack of success, Nordenfeldt built a fourth boat which displayed almost as many unfortunate features as her predecessors and soon was discarded and forgotten.

 In the latter part of the nineteenth century the French Government, which for so many years had shown a strong and continuous interest in the submarine problem, was particularly active. Three different types of boats built in this period under the auspices and with the assistance of the French Government deserve particular attention. The first of these was the Gymnote, planned originally by a well-known French engineer, Dupuy de Lome, whose alert mind also planned an airship and made him a figure in the history of our Panama Canal. He died, however, before his project could be executed. M. Gustave Zédé, a marine engineer and his friend, continued his work after modifying some of his plans. The French Minister of Marine of this period, Admiral Aube who had long been strongly interested in submarines, immediately accepted M. Zédé's design and ordered the boat to be built. As the earliest of successful submarines she merits description:

The Gymnote was built of steel in the shape of a cigar. She was 59 feet long, 5 feet 9 inches beam, and 6 feet in diameter, just deep enough to allow a man to stand upright in the interior. The motive power was originally an electro-motor of 55 horse-power, driven from 564 accumulators. It was of extraordinary lightness, weighing only 4410 pounds, and drove the screw at the rate of two thousand revolutions a minute, giving a speed of six knots an hour, its radius of action at this speed being thirty-five miles.

Immersion was accomplished by the introduction of water into three reservoirs, placed one forward, one aft, and one centre. The water was expelled either by means of compressed air or by a rotary pump worked by an electro-motor. Two horizontal rudders steered the boat in the vertical plane and an ordinary rudder steered in the horizontal.

The Gymnote had her first trial on September 4, 1888, and the Paris Temps described the result in the following enthusiastic language:

She steered like a fish both as regards direction and depth; she mastered the desired depth with ease and exactness; at full power she attained the anticipated speed of from nine to ten knots; the lighting was excellent, there was no difficulty about heating. It was a strange sight to see the vessel skimming along the top of the water, suddenly give a downward plunge with its snout, and disappear with a shark-like wriggle of its stern, only to come up again at a distance out and in an unlooked-for direction. A few small matters connected with the accumulators had to be seen to, but they did not take a month.

Following along the same lines as this boat another boat, considerably larger, was built. Before it was completed, M. Zédé died and it was decided to name the new boat in his honour. The Gustave Zédé was launched at Toulon on June 1, 1893; she was 159 feet in length, beam 12 feet 4 inches, and had a total displacement of 266 tons. Her shell was of "Roma" bronze, a non-magnetic metal, and one that could not be attacked by sea water.

The motive power was furnished by two independent electro-motors of 360 horse-power each and fed by accumulators. In order to endow the boat with a wide radius of action a storage battery was provided.

The successive crews of the Gustave Zédé suffered much from the poisonous fumes of the accumulators, and during the earlier trials all the men on board were ill.

In the bows was a torpedo tube, and an arrangement was used whereby the water that entered the tube after the discharge of the torpedo was forced out by compressed air. Three Whitehead torpedoes were carried. In spite of the fact that a horizontal rudder placed at the stern had not proved serviceable on the Gymnote, such a rudder was fitted in the Gustave Zédé. With this rudder she usually plunged at an angle of about 5°, but on several occasions she behaved in a very erratic fashion, seesawing up and down, and once when the Committee of Experts were on board, she proved so capricious, going down at an angle of 30°-35°, often throwing the poor gentlemen on to the floor, that it was decided to fix a system of six rudders, three on each side.

Four water tanks were carried, one at each end and two in the middle, and the water was expelled by four pumps worked by a little electro-motor; these pumps also furnished the air necessary for the crew and for the discharge of the torpedoes. For underwater vision, an optical tube and a periscope had been provided.

On July 5, 1899, still another submarine boat was launched for the French Navy. She was called the Morse. She was 118 feet long, 9 feet beam, displaced 146 tons, and was likewise made of "Roma" bronze. The motive power was electricity and in many other respects she was very similar to the Gustave Zédé, embodying, however, a number of improvements. M. Calmette, who accompanied the French Minister of War on the trial trip of the Morse, described his experience in the Paris Figaro as follows:
