"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 canals 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 a๋rial 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.
