On August 27, 1914, a bare three weeks into the First World War, the hopes and dreams of the French to liberate their lost provinces of Alsace and Lorraine by beating the German Army were in ashes. Hard and costly defeats had been inflicted on their army by a seemingly relentless grey tide of German soldiers backed by heavy artillery, the likes of which the world had never seen. Worse still, an incoming tide of a million German soldiers cutting through Belgium seemed unstoppable and that Paris would fall in a matter of a week or so. This is the story of how the French army rose from its knees and managed to inflict a stunning and decisive defeat on the German invaders that saved their country from disaster. This is the story of the Miracle of the Marne.
