Guy Sajer was a teenage private.
As anyone who has been in the military knows, privates pretty much do as they are told. They know what is going on in their squad and platoon, but their knowledge of even what their company is doing can be pretty sketchy.
A private’s day is controlled by his sergeants and the German Army had excellent sergeants. Even when they were not up on the line, these sergeants would keep the soldiers busy. They would be constantly digging some sort of hole for a defensive position, or maintaining their equipment, eating and sleeping; when they were not up half the night pulling guard duty.
Once they went up on the line, then you added the confusion of combat, where time and space becomes distorted.
And I mean distorted. I have been in fire fights, and other than it seemed like half the world was shooting at us, I have only vaguest idea of what was happening around me. My focus was totally on MY unit. I sort of knew what my HQ expected and what adjacent units were supposed to be doing, but when I say vaguely knew what the other units were doing, I mean it.
There were no lines or arrows on a map showing the course of the fight, that would come later. During the fight, it was like someone had put a stick in an ant hill and then stirred it around to aggravate the ants. Combat is just utter confusion and chaos.
So I’m sure that if I wrote a book, there would be hundreds of Experts who would tear it apart for all of the inaccuracies.
