World War I

Tuesday marked the 90th anniversary of the end of World War I, with the handful of surviving veterans at the vanguard of commemorations for the fallen of "The War to End All Wars."

Leaders from the powers that fought the war, now allies, gathered at the site of the 1916 Battle of Verdun, where 300,000 men were slaughtered over 11 months of bloody trench warfare.

French President Nicolas Sarkozy paid homage to the sacrifice and suffering of the war's "eight and a half million dead, 21 million wounded, four million widows and eight million orphans."
