(excerpt)

"At the 11th hour on the 11th day of the 11th month of 1918, the Great War ends. At 5 a.m. that morning, Germany, bereft of manpower and supplies and faced with imminent invasion, signed an armistice agreement with the Allies in a railroad car outside Compiégne, France. The First World War left nine million soldiers dead and 21 million wounded, with Germany, Russia, Austria-Hungary, France, and Great Britain each losing nearly a million or more lives. In addition, at least five million civilians died from disease, starvation, or exposure."
