During the Great War, although it is now accepted that sport is a tool for recruiting and preparing corps for combat, its role as a remedy to situations of vulnerability encountered by soldiers is still unknown. At the rear of the front, in the cantonments, but also in hospitals and rehabilitation centres, even in prison camps, sport occupies a special place for soldiers who are physically and psychologically wounded by the horrors of war. This conference aims to return to the place and roles that sport occupies outside of fighting in the lives of soldiers and more particularly in the reconstruction of war wounded.
