My friend Charles "Norm" Stevens thankfully did not die in the war, but he flew over 30 missions as a bombardier during World War II and has written two very personal accounts of his time there. An Innocent at Polebrook describes his time during the war, and The Innocent Cadet describes his training beforehand. I have the honor of being in a writer's group with Norm, and I'll say that, particularly with The Innocent Cadet, he has revealed much of his internal thoughts and emotions in a moving and powerful way. He transforms from someone who was innocent to someone quite wise, with very different views of the world at the end of his military career. Afterwards, he was a high school writing teacher for several years and still continues to educate others.
Also tangentially, for a long time I have wanted to mention the work of PEN Center USA in helping to free writers around the world who are imprisoned for telling stories that seek to reveal truth. Other countries around the world don't have freedom of speech the way we do here. As a result, many people are put into jail, often without fair trial, for writing about the injustices of their country. Through letter writing campaigns (a strategy that has proven very effective in such situations) PEN Center USA has been able to free some of these writers. There's an article on a recent detainee, Nurmuhemmet Yasin, here.
