History reenactors dressed as World War I Austro-Hungarian soldiers look up into a ventilation shaft while walking inside the labyrinthine ruins of Fort de Troyon, a fortress built into a hilltop and one of the many forts used by the French to defend the region around Verdun during World War I, on May 28, 2016 near Verdun, France. The governments of France and Germany will commemorate the 100th anniversary of the World War I Battle of Verdun with ceremonies tomorrow. Approximately 300,000 soldiers lost their lives in the 10-month campaign that was among the most grueling battles of World War I.
