The German people were sustained by a sheer obsession akin to the old-time belief in the potent spell of "the black arts" that their military masters were invulnerable and invincible, that by some power--good or evil, they did not care which--they had been made so, and that the world was bound to fall before them. The nation was immensely strong only as long as that obsession remained unshaken. With its destruction by a series of defeats which were incapable of being explained as "strategic retreats," their morale crumbled and finally collapsed, because it was not sustained, as that of the Allies was sustained in the darkest days of the war, by the faith that they were fighting for all that men hold most sacred. To those who were acquainted with German mentality and psychology, it had been manifest all along that when the end foreordained did come, it would come with catastrophic suddenness. WHERE THE TIDE TURNED It is the general impression that the tide of victory set in with Marshal Foch's splendid movement against the German flank on July 18th. That movement, it is true, started the irresistible sweep of the wave which was destined to engulf and destroy the hideous power of Prussianism. But the tide which gathered and drove forward the waters out of which that wave arose, had turned before. It turned with and through the supreme valor of our marines and other American troops in the _first_ battle at Chateau-Thierry and at Belleau Wood, _in the first week of June_. The American force engaged was small, measured by the standard of numbers to which we have become accustomed in this war, but the story of their fighting will remain immortal and in its psychological and strategic consequences the action will take rank, I believe, among the decisive battles of the war. I am not speaking from hearsay. I was in France during the week preceding that battle, the most anxious and gloomy period, probably, of the entire war. What I am about to relate is based either on authoritative information gathered on the spot, or on my own observations. In telling it, nothing is farther from my thoughts than to wish to take away one tittle from the immortal glory which belongs to the Allied armies, nor from the undying gratitude which we owe to the nations who for four heart-breaking years, with superb heroism, fought the battle of civilization--our battle from the very beginning, no less than theirs--and bore untold sacrifices with never faltering spirit.
