Britain's war in Afghanistan is coming to an end. What does it mean for the soldiers coming home? The Trojan war can tell us a thing or two.

Penelope welcomes Odysseus

The last major deployment of British troops to Afghanistan has taken place ahead of the withdrawal of combat troops at the end of next year. Britain’s wars, for now, are coming to an end. But what does that mean for the soldiers coming home? For some, it’s not the end of the fight but the beginning. The real fight has yet to come, a fight that continues to take lives long after the war has ended. Every war has its after-war and Iraq and Afghanistan are no different; a report published in February by the US Department of Veteran Affairs found that, in 2010, 22 US veterans killed themselves every day, while in the UK more soldiers and veterans took their own lives in 2012 than died in combat in Afghanistan.

The invisible wounds of veterans have long been recognised from the "shell shock" of the first world war to the "nerve problems" of the second, through to the naming of post-traumatic stress disorder (PTSD) by American psychiatrists in the aftermath of the Vietnam war. But the issue of combat related stress is not a new phenomenon. Exploring the far-reaching consequences of war goes all the way back to ancient Greece. The effect war can have, not just on those who fight wars but also on those close to them, was addressed in Homer’s epic poem The Odyssey. After the Trojan war, Odysseus sets off on his journey back to Ithaca, surviving encounters with Lotus Eaters and Sirens only to face another challenge: the homecoming. Homer's poem confronts the issue of how soldiers cope when conflicts end. It asks searching questions: can soldiers ever, truly, return home? Can they survive not just the war itself, but the war's aftermath? Will they bring the war home with them?

The Trojan war provided the Greeks with a platform and context for telling stories about conflict and its effects. According to Edith Hall, professor of classics at King's College London, this direct expertise gave Greek authors the ability to discuss "the cost of war in terms of the mental health of combatants" with a "frankness and sophistication from which we can learn a great deal in the third millennium".

After the “shell-shock” of the first world war  and the “nerve problems” of the second, it may seem as though science and medicine are finally is coming to grips with the problem but in essence science has simply found a fancier name for it. The ancient Greeks, it seems, were experts in what we would now term PTSD.
