More than four million American men were under arms when the conflict ended. Of these, more than two million were upon the fields of France and Italy. These were thoroughly trained in the military art. They had proved their right to be considered among the most formidable soldiers the world has known. Against the brown rock of that host in khaki, the flower of German savagery and courage had broken at Château-Thierry. There the high tide of Prussian militarism, after what had seemed to be an irresistible dash for the destruction of France, spent itself in the bloody froth and spume of bitter defeat. There the Prussian Guard encountered the Marines, the Iron Division and the other heroic organizations of America’s new army. There German soldiers who had been hardened and trained under German conscription before the war, and who had learned new arts in their bloody trade, through their service in the World War, met their masters in young Americans taken from the shop, the field, and the forge, youths who had been sent into battle with a scant six months’ intensive training in the art of war. Not only did these American soldiers hold the German onslaught where it was but, in a sudden, fierce, resistless counter-thrust they drove back in defeat and confusion the Prussian Guard, the Pommeranian Reserves, and smashed the morale of that German division beyond hope of resurrection. The news of that exploit sped from the Alps to the North Sea Coast, through all the camps of the Allies, with incredible rapidity. “The Americans have held the Germans. They can fight,” ran the message. New life came into the war-weary ranks of heroic poilus and into the steel-hard armies of Great Britain. “The Americans are as good as the best. There are millions of them, and millions more are coming,” was heard on every side. The transfusion of American blood came as magic tonic, and from that glorious day there was never a doubt as to the speedy defeat of Germany. From that day the German retreat dated. The armistice signed on November 11, 1918, was merely the period finishing the death sentence of German militarism, the first word of which was uttered at Château-Thierry. Germany’s defiance to the world, her determination to force her will and her “kultur” upon the democracies of earth, produced the conflict. She called to her aid three sister autocracies: Turkey, a land ruled by the whims of a long line of moody misanthropic monarchs; Bulgaria, the traitor nation cast by its Teutonic king into a war in which its people had no choice and little sympathy; Austria-Hungary, a congeries of races in which a Teutonic minority ruled with an iron scepter.
