Since Keegan has been in the news recently, you might try his The Face Of Battle

Try "With The Old Breed".

It's a marine's story of his time on Peleliu and Okinawa.

The Face of Battle is outstanding, a must read, but his book specifically about WWII is Six Armies in Normandy. That's good, but did not impress me as much as his The Mask of Command, which is the only other of his books to equal The Face of Battle, IMHO.
