Over 230 Canadian Army soldiers took their own lives during the Second World War. For many, soldiering seems to have exacerbated stresses and depressions. Their suicide notes and the testimony of family, officers, and bunkmates reveal that wartime disturbance was an important section of the complex array of reasons why. In attempts to explain the motivations for their tragic final actions, the instabilities brought by the Second World War and the stresses of military mobilization must be added to the many biological, social, psychological and circumstantial factors revealed by the proceedings of courts of inquiry. Major military risk factors include: access to firearms, suppression of individual agency, and disruption of the protective networks of friends and family. Some Canadians had a difficult time adjusting to military discipline and authority and were frustrated by their inability to succeed by the measures set by the army. Suicide motivations are complex and it may be too simplistic to say that the Second World War caused these deaths, however, it is not too far to say that the war was a factor in their final motivations. Some men, due to the social pressures and constructs of masculine duty, signed up for active service despite previously existing conditions which should have excused them. Revisiting these traumas can expose the difficulties that some Canadians experienced during mobilization for total war. Many brought deep personal pain with them as they entered military service and for some, the disruptions, frustrations, and anxieties of life in khaki were too great to bear. Like their better-known colleagues who died on the battlefield, they too are casualties of the Second World War.
