We have the same thing with the former prisoners of war, many of whom are still alive, it wasn't just soldiers who were taken prisoners but women and children as well.
If any of you have ever watched the popular films about the St Trinian's school, have a look for the original artwork which created those schoolgirls, it was born in a Japanese prisoner of war camp by a British soldier attempting to amuse others and distract from the horrors of being there. He also drew many pictures though depicting life in the camps and on the infamous Burma Railway which he helped build. ( depicted in the film Bridge on the River Kwai) he wrote several books about his experiences.
Something that as a Guide leader I am humbled by.
