Seriously, I just finished one of the best personal histories I've ever read,
With the Old Breed by E.B. Sledge. He was a Marine on Peleliu and Okinawa, and had a talent for vivid descriptions from foxhole-level. He dwells a lot on two things that most military authors gloss over - the indescribable odor and filth of living and fighting for weeks in mud amidst thousands of corpses in tropical heat, and the visceral hate that brutal battles engender.
There was discussion in a recent thread about how Americans are not as immoral in war as, for example, the Germans were. Sledge's account of what some Marines did to wounded and captured Japanese will dispell that myth.
And you won't want to miss the description of what feet look and smell like when boots are finally removed after a few wet weeks.
