Nevertheless, no just summing up of the last year of the war can fail to award to America the credit of having been the final deciding factor, a credit that belongs alike to the valor and size of her armies, the ability of their officers and the overwhelming might and zeal with which the whole nation had gathered itself up for the delivery of the heaviest blows in its power to give. The rapidly growing evidence of how powerful those blows would be, as shown by our enormous preparations in France and the war spirit and war activities in the United States, had convinced the enemy that unless he won decisive results by the autumn of 1918 there was no possibility of his final victory. And therefore he put forth his supreme efforts during the spring and summer of that year. The enormous scale upon which this country entered upon and carried through its preparations for war both at home and in France sent to high figures the money cost of the war to the United States, but it made immeasurable savings in human life, for anything less would have meant more months of war, even more bloody than the preceding years. The enemy’s determination to win a decisive victory in the spring or summer of 1918 before, he believed, it would be possible for the American Army to make itself felt at the front forced England and France and Italy to make what would have been, without our help, their last stand. They had reached the limit of what they could do and were fighting “with their backs to the wall.” Exhausted by nearly four years of bitter struggle they were almost but not quite strong enough to withstand the final, determined, desperate rush of the foe for which he was gathering together all his powers. And American forces gave the aid that was needed to drive him back. Of high importance among the things that America did to help bring about decision between the battle lines was her share in the final agreement upon unified control of the associated armies in France. It was the voice of the United States Government through its representation in the Supreme War Council that carried the day for this measure and led to the appointment in March, 1918, of Marshal Foch as Generalissimo of the Allied and Associated Armies, an action which military authorities are agreed should have been taken long before and which, when finally brought about, was fruitful of the best results.
