I just read that for the first time last year, on the suggestion of a Freeper. I am well read on WWII, but that book was a real testament to the absolute inhuman brutality of the Pacific War.
I had always thought someone would make something about the Pacific War, but I was disappointed with "Flags of Our Fathers", REALLY disappointed by "The Thin Red Line" and appalled by the absolute butcher job on "Pearl Harbor".
I read “With the Old Breed” when it came out, about 25 years ago, I think, and I still remember it. Eugene Sledge has also also appeared in a number of different documentaries over the years, and his experiences are even more vivid when he recounts them on screen.
Another good book, if you haven’t already read it, is “Goodnight Darkness” by William Manchester.
