War leaves mental scars as well as physical ones and for many veterans, the battle does not always end when the fighting stops. In this episode we chart the changing attitudes to mental health conditions caused by the impact of conflict; from Florence Nightingale's pioneering support for traumatised soldiers in the Crimean War to present day veterans who, even now, can take years to reach out for help for themselves and their families. And we'll hear about a powerful film - Combat Stress 100 - in which former servicemen and women speak out for the first time about their crippling mental health conditions. Trigger warning. This podcast contains reference to military trauma and PTSD
