But even with free access to and unlimited credit in the markets of the world, grave questions of priority had to be decided; the impending exhaustion of the world’s resources in certain raw materials and certain classes of skilled labor demanded constantly increasing consideration. It was of paramount importance, of course, that our own preparations for war should not in the slightest degree delay or lessen the assistance which we had been rendering our allies, and which they had come to regard as perhaps the most important factor in calculating their ability to hold the enemy in check until our military effort could become effective. Furthermore, there had to be taken into consideration the demands of the American Navy, which required heavy forgings and other material, as well as trained labor, of the very type so necessary for the solution of the army ordnance problem. On the assumption that it would be of little avail to build ordnance for use in the field in France unless there were cargo-ships in which to transport it and war-ships to protect those cargo-boats against submarine attack, the requirements of army ordnance were made secondary to the demands of our allies, of our navy, and of our merchant marine. The supreme difficulty encountered in the solution of the ordnance problem is best stated in the words of the Honorable Winston Churchill, then British Minister of Munitions, in his report to the British War Council for the year 1917: “In the fourth year of the war we are no longer tapping the stored-up resources of national industry or mobilizing them and applying them for the first time to war. The magnitude of the effort and of achievement approximates continually to the limits of possibility. Already in many directions the frontiers are in sight. It is therefore not necessary merely to expand, but to go back over the ground already covered and by more economical processes, by closer organization, and by thrifty and harmonious methods to glean and gather a further reinforcement of war power.”
