Question from Arthur - Historical records of what today is called PTSD

I was wondering what is there if any that men returning from battles, might of had symptoms that we would regard today as PTSD? or any evidence for trauma related issue from other incidents in a persons history. I realize its a very hard thing to find evidence for, especially since it was unlikely to have recognised in any manner we do now. But my guess is that issues happened frequently and would of been regarded as madness perhaps. Its something I have done a little research on myself, but would the opinion of others. I also cannot find question on here that covers this in a precise way. Arthur
