Some facts about Verdun may surprise you: Verdun was symbolically important for both sides, had been intended by Germany to be a battle of attrition and caught the French by surprise. It resulted in roughly equal and staggering casualties: 800k dead, wounded or missing with approximately 150 dead–and many unrecoverable remains.
Did the horror and utter failure for both sides create a new era of Franco-German cooperation?
What was the meaning of this now-defining battle of World War I? Paul Jankowski writes:
To a historian 100 years later, Verdun does yield a meaning, in a way a darkly ironic one. Neither Erich von Falkenhayn, the chief of the German General Staff, nor his French counterpart, Joseph Joffre, had ever envisaged a climactic, decisive battle at Verdun. They had attacked and defended with their eyes elsewhere on the front, and had thought of the fight initially as secondary, as ancillary to their wider strategic goals. And then it became a primary affair, self-sustaining and endless. They had aspired to control it. Instead it had controlled them. In that sense Verdun truly was iconic, the symbolic battle of the Great War of 1914-18.
