I got to know Ernest Gordon toward the end of his life. Later connected with his son Alistar. The book (originally titled Miracle of the River Kwaii) went through a few changes. Ernest told me some of the most difficult experiences were edited out as the publisher didn't think the public could handle it. I feel the book was more true to the story and especially the personality of Dusty Miller - a simple man with an extraordinary heart. The movie is well done. If interested in reading I'd see if earlier versions are available anywhere.
