My mother had an uncle who fought briefly in World War I. He was sent home with shell shock, and lived the remainder of his life in a VA hospital in Marion, Indiana. My parents visited him once, but he of course had no idea who they were, or why they were there. His story is one for another time.
But in the meantime, I hope that today - even if you end up in the rain - you will take a moment to say a prayer or have a thought for his soul, and all of the souls who only tried to do what was asked.
This is one of the few poems or songs that really captures the sadness of the war to me. Have a listen, and be glad that these soldiers, those who came after them, and those who are in harm's way still, make it possible for us to have the right to rail against war.
