The Forgotten Soldier: Last Three Parts

I finished The Forgotten Soldier today.
The last three parts consisted of:
The Retreat
To the West
The End

One part that really stood out to me was when Sajer told the reader how to read a war story. You shouldn't be sitting comfortably, sipping coffee and waiting to go to work. No, you should be standing, and reading close to the time you would go to bed, so you would be tired, but not tired enough to actually fall asleep. This is the west war book I've read so far.
