The major powers in Europe prepare for war. In this episode, the soldiers learn lessons ignored from the Franco Prussian war. The Soldier as a pawn. Britain’s professional Army versus Germany’s conscripts. Early war technology and tactics, the Grand Strategy and French Élan all leading to the call to arms. Though the Great War is remembered as one of the costliest conflicts in history, much of it was fought over a relatively small and blood-soaked swathe of France and Flanders. It is also striking for the great change and innovation in the art of war.
