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.
He is a lib (or was) but I sure do respect him for his service, and he did write a great biography of Winston Churchill “The Last Lion”.
