After several satisfactory ascents to the height of above 500 feet had taken place—the balloon being held easily by ten men, five to each guy-rope—an order was given, in April 1794, for the formation of a company of military aeronauts—styled aerostiers, to which Coutelle was appointed captain-commandant. His company consisted of one lieutenant, one sergeant-major, one sergeant, two corporals, and twenty privates, who wore a dark blue uniform, with black velvet facings, and were armed with pistols and swords.
This new and peculiar company of aerostiers was very soon sent to join the army at Maubeuge, and was regarded with some ridicule and contempt by the rest of the army. Coutelle, however, took an effectual method of commanding respect. He begged that he and his men might be allowed to take part in a projected sortie. They were permitted, and went; an officer and private were wounded, and the corps behaved with such gallantry that it was from that time treated with becoming respect.
Ascents were made daily in the balloon for reconnoitring purposes, and the Austrians fired at their audacious and inquisitive enemy both with muskets and cannon, but without effect.
After a time the balloon was ordered to take the road, and join that part of the army which was marching on Charleroi. Its march through the country in leading-strings was curious to spectators and harassing to the aerostiers. The car, with all its appurtenances, was placed on a cart, over which the balloon was allowed to float at a height sufficient to admit of the passage of cavalry under it. Twenty men, marching in single file, held it down by twenty stays; but they had a sad time of it, for their charge was headstrong and restive, jerking and tugging at them continually, not only with its own inherent power of ascension, but with the irregular impetus derived from gusts and squalls of wind, which caused it to make sudden and violent charges against trees, houses, or whatever chanced to come in its way, and sometimes to beat its blunt forehead wildly on the ground as if it had been a monster in despair!
It reached Charleroi, however, on the 22nd of June, after a journey of three days, and took part in the battle of Fleurus on the 26th. A high wind rendered it necessary, on the day of battle, to fasten its guy-ropes to thirty horses—fifteen to each rope—and, thus secured, it remained in the air eight hours, passing from place to place, and making observations. Its services were so highly appreciated by the generals on that occasion that a second balloon was made and sent to the field of action. The first one, which was named l’Entreprenant, met with accidents which rendered it necessary that it should be sent to Maubeuge for repair; but it afterwards rejoined the army and took part in the battle of Aldenhoven, at the capture of Bonn, and at the operations before Ehrenbreitstein, in all of which it escaped without a wound, although frequently exposed to a furious fire of musketry and shells from the exasperated Austrians.
Nevertheless, its natural enemy, the wind, did not allow it to escape scatheless, as Coutelle shows in one of his letters. He writes thus:
“I received orders to make a reconnaissance of Mayence. I accordingly posted myself between our lines and the town, at about half cannon-shot distance. The wind was very high, so, to counteract its effects as far as lay in my power, I ascended alone, with two hundred pounds additional buoyancy. I was at a height of five hundred metres when three successive gusts dashed me to the ground with such violence that several portions of the car were smashed to bits. Each time the balloon darted up again with so much force that sixty-four men—thirty-two at each guy-rope—were dragged to some distance. Had the guys been made fast to grapnels, as had been suggested to me, they must infallibly have given way.”
Notwithstanding this rough treatment, the aerial warrior managed, during a lull in the wind, to count the number of the enemy’s guns.
But the successes of these war-balloons were sadly intermingled with reverses of fortune and harassing difficulties. The aeronauts had, indeed, won the respect and admiration of the army, but this did not compensate for the terribly fatiguing work of holding on, with scarcely a moment’s intermission, to the ropes of the intractable monsters during long and frequent marches. The second balloon at length succeeded in breaking loose, and was so much damaged as to become unserviceable, and the first one was afterwards found riddled with balls—destroyed, it was supposed, by its own men, who had become tired of the hardships to which they were continually subjected. The balloon was repaired, but was taken prisoner at Wurtzburg in September 1796, after a short but brilliant, and, it is said, useful career.
After this the war-ballooning fell into disrepute. Some attempts have been made in modern times to revive it, but these are not worth mentioning.
Having treated of the balloon in all its different aspects, it is both just and appropriate to conclude with an account of the theory and construction of that curious machine which is, according to some enthusiastic aeronauts, to supplant the balloon altogether, and enable us to accomplish that which has been one of the great aims and desires of mankind from the earliest ages, namely, the directing of our flight, or steering a course, not only through, but, if need were, in opposition to the winds.
Monsieur Nadar being, perhaps, the most zealous advocate of this machine, we draw our information chiefly from his writings. Of course the reader will understand that we do not support the views which we are about to set forth; neither, however, do we treat them lightly, because we have lived long enough to see proposals which, not many years ago, would have been deemed worthy of the most visionary of lunatics, carried out to a successful issue and reduced to sober facts.
When we hear of a flying machine which is to rise from the earth at the bidding of man, and, like the fabulous creations in the Arabian Nights’ Entertainment, dart through the air with passengers and luggage bound for definite localities, turning hither and thither, or alighting on the earth according to the will of a steersman—we confess to a feeling which is apt to wrinkle our visage with the smile of incredulity; but we sternly rebuke the smile, for we know that similar smiles wreathed the faces of exceedingly wise people when, in former days, it was proposed to drive ships and coaches by steam, and hold instantaneous converse with our friends across the Atlantic by means of electricity!
Let us therefore gravely consider the aerial locomotive.
Monsieur Nadar, as the reader already knows, scouts the idea of steering balloons.
In reference to this he states with truth that, “a balloon which presents to the action of the atmosphere a volume of from 22,000 to 42,000 (cubic) feet of a gas from ten to fifteen times lighter than air, is, by its very nature, smitten with incapacity to struggle against the slightest current, no matter what may be the resisting motive force which may be imparted to it. Both by its constitution, and by the medium which drives it hither and thither at the pleasure of the winds, it can never become a vessel. It is a buoy, and remains a buoy.”
Discarding, therefore, with contempt, the balloon as an aerial locomotive, he announces his belief that it is the screw which is destined to drive us, or clamber with us, into the blue vault above, and convey us from place to place. And here it is right to assure the reader that the theoretical power of the screw to accomplish the end in view is not a disputable question. It has been practically proved by models, and the only point that remains to be settled is the possibility of applying the power to machines large enough to carry human beings with a sufficient degree of safety to warrant risking the attempt.
Monsieur Nadar sets out with a statement which he deems self-evident, namely, that, “in order to contend against the air, we must be specifically heavier than the air”—a truth which was also, we are told, announced by the first Napoleon in the epigrammatic sentence, “There can be no progress without resistance.” From this the Frenchman proceeds to prove that, in order to command the air, it is necessary to support one’s-self upon it, instead of being at its mercy; that we can only rest upon that which resists, and that the air itself furnishes us amply with the needful resistance—it being “the same atmosphere which overturns walls, tears up by the root trees a century old, and enables ships to ascend impetuous currents.” Glowing with the ardour of a man whose faith is refreshingly great, he tells us that the time has at last come when the atmosphere must yield to man. “It is for man,” he says, “to restrain and subdue this insolent and abnormal rebellion, which has for so many years laughed at our vain efforts. We are in turn about to make it serve us as a slave, just as the water on which we launch the ship, as the solid earth on which we press the wheel!”
There is a toy called the spiralifer, which is common enough in towns, and which is, doubtless, known to almost every one. It consists of four flat fans attached to a spindle somewhat after the manner of the arms of a windmill. It is placed in a hollow tube and made to spin violently by pulling a string wound round the spindle. The result is that the spiralifer leaps out of the hollow tube and ascends powerfully as long as the violent spinning motion continues. If properly constructed, this toy acts with great force and certainty, and if the spinning motion could only be kept up, by any means, the ascent would be continued. The principal here involved is precisely the same as that which causes a windmill to turn, a screw-propeller to drive a ship, and a cork-screw to enter a cork. It is pressure against a resisting medium. Air is the resisting medium in the case of the mill; water and cork respectively in the other cases. The only difference between the windmill and the spiralifer is, that the first is moved by the air pressing against it, the other by itself, in its rotatory action, pressing against the air. If you turn a bottle upside down, and, while in that position, send a cork-screw up into the cork, you set in motion the same force which is applied in the spiralifer. As the screw screws itself up into the cork, so the spiralifer screws itself up into the air. Of course the screw remains sticking there when the motive power ceases, because of the density of the medium through
