"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 illustrated 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 shells 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."
