In this episode we look at the struggles of the soldiers who suffered from shell shock.  Probably over 250,000 men suffered from ‘shell shock’ as result of the First World War. At the time it was believed to result from a physical injury to the nervous system during a heavy bombardment or shell attack, later it became evident that men who had not been exposed directly to such fire were just as traumatised. We listen to the voices of men who had seen others suffer from this condition, and from some of the soldiers directly affected. And we discover the story of a shell shocked Canadian soldier who murdered a girl in Liverpool.
