During WW I, Les Foyers du Soldat was one of the three official welfare organizations; the Red Cross and the Y.M.C.A. were the other two serving French troops. They set up canteens for soldiers to go to while on leave, providing a place to sleep, relax, eat, bathe; they even provided entertainment such as music or films.
Caleb served as the American Regional Y.M.C.A. director in France from 1917-1918 and established 148 barracks and dug-outs on the French front line in an effort to improve the morale of the French army.
