That's a good question.
I've only read a few books on the battles in the Pacific. A couple of the naval battles and one on Okinawa.
I went over to my library website and looked up what was available there.
There's quite a few actually but one caught my eye:
"Iwo Jima: Legacy of Valor" by Bill D. Ross
- An hour by hour account of the largest and most brutal assault ever conducted by the Marine Corps.
Doing some research I found this snippet from the New York Times book review.
"Bill D. Ross has written that book. I consider it the best book on a campaign and on a fighting force, in this case the Marines, since Alan Moorhead's work on El Alamein. The author's research has been thorough. He has read, as far as I can see, most of the writing, published and unpublished on Iwo Jima, and he has given us a splendid book."
Another book now added to my list
