This was a somewhat random thought that came from a conversation at work about PTSD in soldiers returning from Afghanistan or Iraq. I've seen stuff relating to combat stress, shell shock, of PTSD in soldiers who fought in the Middle East, Vietnam, Korea, the world wars, and even some Napoleonic wars. However, I've never seen anything mention how soldiers during ancient or medieval periods would mentally handle the horrors of war. Was this simply due to limited ability to document such things or was the brutality of the time periods just considered normal and people became numb? It would just seem that conflicts that may involve battles were thousands of men would kill each other with spears, swords, and arrows would affect the mental health of those lucky enough to survive.
