"Germany feels that the decisive phase of the war is imminent and the efforts she will make next year will be infinitely greater than any she has made before. She will try in every way to regain the supremacy of the air. Realizing what a formidable enemy America can be in the air, she will strengthen her aviation forces in consequence.

"The aeroplane is by far the most powerful of all the modern weapons. If the Allies have the supremacy of the air the German artillery will lose its accuracy of aim. It is impossible, because of the long range, for modern guns to fire without the help of airplanes. The accuracy of artillery fire depends entirely on its being directed by an airplane.

"This was clearly ill.u.s.trated during the battle of the Somme in 1916. The French at that time had concentrated such a large number of fighting machines that no German machine was allowed to fly over the lines. On the other hand, the Allies' reconnaissance machines were so numerous that each French battery could have its fire directed by an airplane.

"The destruction of the enemy positions was in consequence carried out very effectively and very rapidly, while the Germans were obliged to fire blindly and scatter their sh.e.l.ls over large areas, incapable as they were of locating our battery emplacements and the positions of our troops. Unluckily, a few weeks later the Germans had called from the different parts of the line a good many of their squadrons, and were able to carry out their work under better conditions.

"We need such a superiority that it will be impossible for any German airplane to fly anywhere near the lines.

"Every German kite balloon, every airplane would immediately be attacked by a number of allied machines. In this way the German aviation will not only be dominated but will be entirely crushed.

"If we can prevent the Germans from seeing, through their airplanes, what we are preparing we will be very near the end of the war. It will require a huge effort to carry out this plan.

Neither the English nor the French are able to do so by their own means.

"As far as France is concerned, she is able to keep on building machines rapidly enough to increase her aviation corps at about the same rate as Germany is increasing hers. If she wanted to double or triple her production of machines she could do so, but she would have to call back from the trenches a certain number of skilled workmen, and this would weaken her fighting power. She needs in the trenches all the men who are able to carry a rifle.

"If the Allies are to have the absolute supremacy of the air which we have been describing it will be the privilege of America to give it to them. We want three or four or even five allied machines for one German. America only has the possibilities of production which would allow her to build an enormous number of machines in a very short time.

"The airplane is a great engine of destruction. It tells the artillery where to fire, it drops bombs, it gives the enemy all the information he needs to plan murderous attacks. Drive the German airplanes down and you will save the lives of thousands of men in our trenches. As Ulysses in the cavern put out the eye of the Cyclops, so the eyes of the beast must be put out before you can attempt to kill it."

Major Tulasne and Lieutenant de la Grange then outlined what the aviation programme of the United States should be, saying:

"American industry must be enabled to begin building at once. No time must be lost in experiments. America must profit by the experience of the Allies. She must choose the best planes and build thousands of them.

"She must build reconnoissance machines which she will need for her army; she must build a large number of fighting machines because it is these machines that will destroy German planes; she must also build squadrons of powerful bombing machines which will go behind the German lines to destroy the railway junctions and bomb the enemy cantonments, so as to give the soldiers no rest even when they have left the trenches.

"Bombing done by a few machines gives poor results. The same cannot be said of this operation carried out by a large number of machines which can go to the same places and bomb continually.

"Besides the number of men that are actually killed in these raids, great disturbance is caused in the enemy's communication lines, thereby hindering the operations. For example, since the British Admiralty has increased the number of its bombing squadrons in northern France and has decided to attack constantly the two harbours of Ostend and Zeebrugge and the locks, bridges, and ca.n.a.ls leading to them they have greatly interfered with the activity of these two German bases.

"It is certain that shortly, owing to this, these two ports will no more be used by German torpedo boats and submarines. What the English Royal Naval Air Service has been able to accomplish with 100 machines the Flying Corps of the United States with 1000 machines must be able to carry out on other parts of the front.

"The work of the bombing machines is rendered difficult now by the fact that the actual lines are far from Germany. But it is hoped that soon fighting will be carried on near the enemy frontier and then a wonderful field will be opened to the bombing machines.

"All the big ammunition factories which are in the Rhine and Ruhr valleys, like Krupp's, will be wonderful targets for the American bombing machines. If these machines are of the proper type--that is to say, sufficiently fast and well armed and able to carry a great weight of bombs--nothing will prevent them from destroying any of these important factories.

"As Germany at the present time is only able to continue the war because of her great stock of war material the destruction of her sources of production would be the end of her resistance. For this also the Allies must turn to America. Such a large number of machines is required to produce results that America must be relied on to manufacture them.

"Every man in this country must know that it is in the power of the United States, no matter what can be done in other fields, to bring the war to an end simply by concentrating all its energies on producing an enormous amount of material for aviation, and to enlist a corresponding number of pilots. But this will not be done without great effort. In order to be ready for the great 1918 offensive work must be begun at once."

The extreme secrecy which in this war has characterized the operation of the governments--our own most of all--makes it impossible to state the amount of progress made in 1917 in the construction of our aerial fleet. During the debate in Congress orators were very outspoken in their prophecies that we should outnumber the Kaiser's flying fleet two or three to one. The press of the nation was so very explicit in its descriptions of the way in which we were to blind the Germans and drive them from the air that it is no wonder the Kaiser's government took alarm, and set about building additional aircraft with feverish zeal. In this it was imitated by France and England. It seemed, all at once about the middle of 1917, that the whole belligerent world suddenly recognized the air as the final battlefield and began preparations for its conquest.

All statistical estimates in war time are subject to doubt as to their accuracy--and particularly those having to do in any way with the activities of an enemy country. But competent estimators--or at any rate shrewd guessers--think that Germany's facilities for constructing airplanes equal those of France and England together.

If then all three nations build to the very limit of their abilities there will be a tie, which the contribution of aircraft from the United States will settle overwhelmingly in favour of the Allies.

How great that contribution may be cannot be foretold with certainty at this moment. The building of aircraft was a decidedly infant industry in this country when war began. In the eight years prior to 1916 the government had given orders for just fifty-nine aircraft--scarcely enough to justify manufacturers in keeping their shops open. Orders from foreign governments, however, stimulated production after the war began so that when the United States belatedly took her place as national honour and national safety demanded among the Entente Allies, Mr. Howard E. Coffin, Chairman of the Aircraft Section of the Council of National Defence was able to report eight companies capable of turning out about 14,000 machines in six months--a better showing than British manufacturers could have made when Great Britain, first entered the war.

A feature in the situation which impressed both Congress and the American people was the exposure by various military experts of the defenceless condition of New York City against an air raid by a hostile foreign power. At the moment, of course, there was no danger. The only hostile foreign power with any considerable naval or aerial force was Germany and her fleet was securely bottled up in her own harbours by the overpowering fleet of Great Britain. Yet if one could imagine the British fleet reduced to inefficiency, let us say by a futile, suicidal attack upon Kiel or Heligoland which would leave it crippled, and free the Germans, or if we could conceive that the German threat to reduce Great Britain to subjection by the submarine campaign, proved effective, the peril of New York would then be very real and very immediate. For, although the harbour defences are declared by military authorities to be practically impregnable against attack by sea, they would not be effective against an attack from the air. A hostile fleet carrying a number of seaplanes could round-to out of range of our sh.o.r.e batteries and loose their flyers who could within less than an hour be dropping bombs on the most congested section of Manhattan Island. It is true that our own navy would have to be evaded in such case, but the attack might be made from points more distant from New York and at which no scouts would ever dream of looking for an enemy.

The development in later months of the big heavily armed cruising machines makes the menace to any seaport city like New York still greater. The Germans have built great biplanes with two fuselages, or bodies, armoured, carrying two machine guns and one automatic rifle to each body. They have twin engines of three hundred and forty horse power and carry a crew of six men. They are able in an emergency to keep the air for not less than three days. It is obvious that a small fleet of such machines launched from the deck of a hostile squadron, let us say in the neighbourhood of Block Island, could menace equally Boston or New York, or by flying up the Sound could work ruin and desolation upon all the defenceless cities bordering that body of water.

Nor are the Germans alone in possessing machines of this type. The giant Sikorsky machines of Russia, mentioned in an earlier chapter, have during the war been developed into types capable of carrying crews of twenty-five men with guns and ammunition. The French, after having brought down one of the big German machines with the double bodies, instantly began building aircraft of their own of an even superior type. Some of these are driven by four motors and carry eleven persons, besides guns and ammunition. The Cap.r.o.ni machines of Italy are even bigger--capable of carrying nine guns and thirty-five men. The Congressional Committee was much impressed by consideration of what might be done by a small fleet of aircraft of this type launched from a hostile squadron off the Capes of Chesapeake Bay and operating against Washington. It is not likely that any foreign foe advancing by land could repeat the exploit of the British who burned the capitol in 1812. But in our present defenceless state a dozen aircraft of the largest type might reduce the national capitol to ruins.

If an enemy well provided with aerial force possesses such power of offence an equal power of defence is given to the nation at all well provided with flying craft. In imitation, or perhaps rather in modification, of the English plan for guarding the coasts of Great Britain, a well matured system of defending the American coasts has been worked out and submitted to the national authorities. It involves the division of the coasts of the United States into thirteen aeronautical districts, each with aeronautical stations established at suitable points and all in communication with each other. Eight of these districts would be laid out on the Atlantic Coast extending from the northern boundary of Maine to the Rio Grande River.

Just what the purpose and value of these districts would be may be explained by taking the case, not of a typical one, but of the most important one of all, the third district including the coast line from New London, Conn., to Barnegat Inlet, New Jersey. This of course includes New York and adjacent commercial centres and the entrance to Long Island Sound with its long line of thriving cities and the ports of the places from which come our chief supplies of munitions of war. It includes the part of the United States which an enemy would most covet. The part which at once would furnish the richest plunder, and possession of which by a foe would most cripple this nation. To-day it is defended by stationary guns in land fortresses and in time of attack would be further guarded by a fringe of cruising naval vessels. Apparently up to the middle of 1917 the government thought no aerial watch was needed.

But if we were to follow the methods which all the belligerent nations of Europe are employing on their sea coasts we would establish in this district ten aeronautical stations. This would be no match for the British system which has one such station to every twenty miles of coast. Ours would be farther apart, but as the Sound could be guarded at its entrance the stations need only be maintained along the south sh.o.r.e of Long Island and down the Jersey coast. Each station would be provided with patrol, fighting, and observation airplanes. It would have the mechanical equipment of microphones, searchlights, and other devices for detecting the approach of an enemy now employed successfully abroad. Its patrolling airplanes would cruise constantly far out to sea, not less than eighty miles, keeping ever in touch with their station. As the horizon visible from a soaring airplane is not less than fifty miles distant from the observer, this would mean that no enemy fleet could approach within 130 miles of our coast without detection and report. The Montauk Point station would be charged with guarding the entrance to Long Island Sound and, the waters of Nantucket shoals and Block Island Sound where the German submarine U-53 did its deadly work in 1916. The Sandy Hook station would of course be the most important of all, guarding New York sea-going commerce and protecting the ship channel by a constant patrol of aircraft over it.

The modern airplane has a speed of from eighty to one hundred and sixty miles an hour--the latter rate being attained only by the light scouts. Thus it is apparent that if an alarm were raised at any one of these stations between New London and Barnegat three hours at most would suffice to bring the fighting equipment of all the stations to the point threatened. There would be thus concentrated a fleet of several hundred swift scouts, heavy fighting machines, the torpedo planes of the type designed by Admiral Fiske, hydroaeroplanes capable of carrying heavy guns and in brief every form of aerial fighter. Moreover, by use of the wireless, every ship of the Navy within a radius of several hundred miles would be notified of the menace. They could not reach the scene of action so swiftly as the flying men but the former would be able to hold the foe in action until the heavier ships should arrive.

The enormous advantage of such a system of guarding our coasts needs no further explanation. It is not even experimental, for France on her limited coast has 150 such stations. England, which started the war with 18, had 114 in 1917 and was still building. We at that time had none, although the extent of our sea coast and the great multiplicity of practicable harbours make us more vulnerable than any other nation.

CHAPTER X

SOME FEATURES OF AeRIAL WARFARE

As devices to translate German hate for England into deeds of b.l.o.o.d.y malignancy and cowardly murder the German aircraft have ranked supreme. The ruthless submarine war has indeed done something toward working off this peculiar pa.s.sion, but it lacked the spectacular qualities which German wrath demanded. As the war proceeded, and it became apparent that the partic.i.p.ation of Great Britain--at first wholly unexpected by the Kaiser's advisers--was certain to defeat the German aims, the authorities carefully inculcated in the minds of the people the most malignant hatred for that power. As Lissauer's famous hymn of hate had it--

French and Russians it matters not, A blow for a blow, and a shot for a shot.

We have one foe and one alone-- England!

By way of at once gratifying this hatred and still further stimulating it the German military authorities began early in the war a series of air raids upon English towns. They were of more than doubtful military value. They damaged no military or naval works.

They aroused the savage ire of the British people who saw their children slain in schools and their wounded in hospitals by bombs dropped from the sky and straightway rushed off to enlist against so callous and barbaric a foe. But the raids served their political purpose by making the German people believe that the British were suffering all the horrors of war on their own soil, while the iron line of trenches drawn across France by the German troops kept the invader and war's agonies far from the soil of the Fatherland.

[Ill.u.s.tration: International Film Service.

The first German air raids were by Zeppelins on little English seaside towns--Scarborough, Hartlepool, and Harwich. Except in so far as they inflicted mutilation and death upon many non-combatants, mostly women and children, and misery upon their relatives and friends they were without effect. But early in 1915 began a systematic series of raids upon London, which, by October of 1917, had totalled thirty-four, with a toll of 865 persons killed, and 2500 wounded. It seems fair to say that for these raids there was more plausible excuse than for those on the peaceful little seaside bathing resorts and fishing villages. London is full of military and naval centres, a.r.s.enals and navy yards, executive offices and centres of warlike activity. An incendiary bomb dropped into the Bank of England, or the Admiralty, might paralyze the finances of the Empire, or throw the naval organization into a state of anarchy.

But as a matter of fact the German bombs did nothing of the sort.

They fell in the congested districts of London, "the crowded warrens of the poor." They spread wounds and death among peaceable theatre audiences. One dropped on a 'bus loaded with pa.s.sengers homeward bound, and obliterated it and them from the face of the earth. But no building of the least military importance sustained any injury.

It is true, however, that the persistent raiding has compelled England to withhold from the fighting lines in France several thousand men and several hundred guns in order to be in readiness to meet air raids in which Germany has never employed more than fifty machines and at most two hundred men, including both aviators and mechanics.

It is entirely probable that the failure of the Germans to strike targets of military importance and the slaughter they wrought among peaceful civilians were due to no intent or purpose on their part.

Hitting a chosen target from the air is no matter of certainty. The bomb intended for the railway station is quite as likely to hit the adjacent public school or hospital. If the world ever recurs to that moderate degree of sanity and civilization which shall permit wars, but strive to regulate them in the interest of humanity this untrustworthiness of the aircraft's aim will compel some form of international regulation, just as the vulnerability of the submarine will force the amendment of the doctrine of visitation and search.

But neither problem can be logically and reasonably solved in the middle of a war. And so, while the German violation of existing international law had the uncomfortable result for Germany of bringing the United States into the war, the barbarous raids upon London caused the British at last to turn aside from their commendable abstention from air raids on unfortified and non-military towns and prepare for reprisals in kind.

From the beginning of the war the British had abstained from bombing peaceful and non-military towns. They had not indeed been weak in the employment of their air forces. General s.m.u.ts speaking in October, 1917, said that the British had, in the month previous, dropped 207 tons of bombs behind the lines of the enemy. But the targets were airdromes, military camps, a.r.s.enals and munitions camps--not hospitals or kindergartens. The time had now come when this purely military campaign no longer satisfied an enraged British people who demanded the enforcement of the Mosaic law of an eye for an eye and a tooth for a tooth, against a people whom General s.m.u.ts described as "an enemy who apparently recognizes no laws, human or divine; who knows no pity or restraint, who sung Te Deums over the sinking of the _Lusitania_, and to whom the maiming and slaughter of women and children appear legitimate means of warfare."

And Premier Lloyd George, speaking to an audience of poor people in one of the congested districts which had suffered sorely from the aerial activities of the Hun, said:

"We will give it all back to them, and we will give it soon. We shall bomb Germany with compound interest."
