Pierre Teilhard participated in the Great War from 12 December 1914. He will be demobilized on March 10, 1919. During these four years, he will travel the Front by participating in all the major events such as Verdun and the Chemin des Dames … After the war, he retraced his various travels on a unique map which is currently kept at the Pierre Teilhard de Chardin Foundation. 

This Powerpoint has been realized by Chantal AMOUROUX from this map in order to present chronologically its movements.
