Second Lieutenant Wilfred Owen was twenty-four years old when he was admitted to the newly established Craiglockhart Military Hospital for treatment of war-induced shock. An aspiring poet, trying to understand the horror he had witnessed, he read a collection of poems by a fellow officer, Siegfried Sassoon, and was impressed by the depiction of the soldier's fate. A month later, Sassoon also arrived at Craiglockhart, having refused to return to the front after being injured during battle. During their months at Craiglockhart, they each encouraged the other in their work, as well as in their personal quest regarding the morality of war and their treatment. The treatment provided Owen, Sassoon, and their fellow inmates with insights that allowed them to express themselves better, and for the 28 months that Craiglockhart was in operation, it effectively incubated the most significant developments of the era in both psychiatry and poetry. "Soldiers Don’t Go Mad" tells for the first time the story of the soldiers and doctors who grappled with the effects of industrial warfare on the soul. Examining the roots of what we now know as PTSD, Glass highlights the historical significance of how we must consider the devastating effects of war on mental health, as well as the ways in which creative work helps us regain our sanity even in the darkest of times.
