Verdun

In 1916, the Battle of Verdun between the French and Germans was perhaps the most demanding battle in world history. The struggle started when the Germans attacked Verdun, France, a city surrounded by a ring of underground forts. At least 220,000 soldiers died, and at least 480,000 were wounded in this 10-month struggle that accomplished nothing. At the end the front lines were in nearly the same locations as at the beginning.
