While Jonathan Shay’s connections between Vietnam and Homer’s literature of war are one way of exploring the perennial risk of psychological injuries in war, the history of another country’s wars and experiences might offer a promising avenue of approach. Canadian historian Adam Montgomery’s book should thus be of interest to a wider audience than its subtitle alone might suggest. While students of Canadian military history will welcome it as a concise history of psychological injury and treatment in Canada’s wars since 1914, Montgomery usefully broadens the scope of the discussion. American readers, understandably preoccupied with the U.S. experience in Iraq and Afghanistan, will find the treatment of an allied and culturally similar military illuminating. Montgomery’s findings point to the startling ubiquity of psychological injuries in military operations of all types.
