According to Wilfrid Wilson Gibson´s poem "back" , show us the sad story of a men who has been in a far away land, fighting a war that was not his war, leaving every piece of his soul in any man he killed, until can not recognize himself, so the question would not be "where he´s been and what he´s done" it would be more like asking Will you finally be able to find your soul?.
Wilfred Wilson Gibson (1878-1962), was borned in England, he was a soldier in the war and served in the infantry on the western front, what he`s done was to kill people in the war, altough he ironicaly says, "It wasn't I", wich indicates he doesn't recongise his action in the war.
