World War I saw the advent of many terrible weapons and tactics to deal with those weapons. Pullman employees suffered hideous injuries and traumatic experiences. Christian Anderson lost both arms and suffered head and foot wounds in the battle for Argonne Forest. Arthur Last lost a leg and part of his jaw at the battle of Chateau Thierry. John Kloet lost a leg in Flanders. Hugh Davidson suffered from gas poisoning. Edward Prybylski wrote movingly of suffering from a mustard gas shelling attack and his recovery in a field hospital. W. H. Zimmerman wrote of learning to live with blindness after the truck we was riding in swerved to avoid a shell hole and skidded out of control. Alex Gronquist floated in the water for hours after his ship, the Tuscania, was torpedoed off the coast of Ireland by a German submarine. Walter Henning floated for 22 hours before being rescued after his ship, the Aurora, was torpedoed by a German submarine. Cyrill M. Angell lost control of his aircraft somewhere over Belgium on routine patrol and crashed.
