Yes, that's it: "Johnny got his gun." I knew that Johnny was in there somewhere. You're rignt, the book was a tough read but the subject made it worthwile. It came to me more as a tribute to those incapacitated by that war and the quiet, and often solitary, bravery those men exhibited.
Thanks again for helping me remember the title.
