In August 1914, the German army launched an invasion of Belgium as a first step to their planned march through France and capture of Paris. As the Germans swept through Belgium and advanced on the French capital, the Allies made a desperate stand along the Marne River. The resulting “Miracle on the Marne” halted the German advance and ended hopes of a quick war. What followed was the grim birth of trench warfare and a conflict that would grind on for years. In this episode, James and Sean explore the opening months of World War I in the west— from Germany’s Schlieffen Plan and France’s doomed offensives to the brutal fighting of the Battle of the Frontiers and the halting of the German onslaught.
