That effect upon the Germans was in itself of tremendous significance; but the historic effect was greater, and will grow in importance with the passage of time, for it is a fact, unperceived by onlooking nations at the moment, that it was the turning point of the war; and that the turning was accomplished by troops of a nation that hated war and was supposed to be incapable of military development; and that these troops had met and whipped the choicest troops of a power that above all things was military, that had assumed proprietary rights in the art of war, and believed itself invincible. Late in February, 1918, General Ludendorff had told a Berlin newspaper correspondent that on the first of April he would be in Paris. It was inconceivable to the Germans that with the thorough preparation of a mighty army for an offensive that by sheer weight of numbers should drive through an opposition twenty times as strong as that which then confronted them, they could not with ease push in between the French and British forces, thrust straight through to Paris (as a spectacular performance rather than a vital military operation), and then walk over to the channel ports of France and bring both France and England to a plea for mercy. From the 21st of March until along in May, 1918, it looked as though they might succeed. That is, to anyone unaware of the strategy of Marshal Foch, who sold terrain by the foot for awful prices in German lives, and held an unbroken front until such time as American forces could be brought into action, instead of wearing out his reserves and weakening his power for an offensive. Unity of command had been accomplished by that time at the urgent demand of the United States Government. Foch had saved France and the world at the first battle of the Marne. Being given supreme authority over all the allied forces, as soon as the arrival of American troops in great numbers had been thoroughly established, he was ready; and the offensive passed from German to allied hands. The tremendous German drive, which Ludendorff had confidently promised the German people would bring a smashing and decisive victory, was stopped. Retrocession began. On the Marne again, in July, 1918, in the sector held by Americans an action began at Chateau Thierry which forced the German retreat that in a few weeks was to shake the heart of Germany, scare out Bulgaria, Austria and Turkey, in the early autumn bring Germany to a plea for peace, send Ludendorff himself into retirement, dethrone the Kaiser, do away with the imperial form of government, set up a republic, and create conditions that would quash for all time the power of Prussia to disturb a decent world.
