This 1940 book by Charles S. Myers, Consulting Psychologist to the British Armies in the First World War, explains his work on shell shock.

More than 16,000 Canadian soldiers suffered from shell shock during the Great War of 1914 to 1918. Despite significant interest from historians, we still know relatively little about how it was experienced, diagnosed, treated, and managed in the frontline trenches in the Canadian and British forces. How did soldiers relate to suffering comrades? Did large numbers of shell shock cases affect the outcome of important battles? Was frontline psychiatric treatment as effective as many experts claimed after the war? Were Canadians treated any differently than other Commonwealth soldiers? A Weary Road is the first comprehensive study to address these important questions. Author Mark Osborne Humphries uses research from Canadian, British, and Australian archives, including hundreds of newly available hospital records and patient medical files, to provide a history of war trauma as it was experienced, treated, and managed by ordinary soldiers.
