'With the Old Breed' by E.B. Sledge.
I first got this book in paper form, then got the audiobook.
It describes the Pacific battles of Peleliu and Okinawa during WWII.
It is a very personal book for me.
My Dad fought in both battles (1st Marine Division) and where he was wounded.
It gave me an insight into what it must have been like for him, still a teenager, to face such death
and then move on to the next Island.
Gave me a better understanding of the man he turned out to be.
