What is the major conflict in John Chioles' "Before the Firing Squad"?

A major conflict in the story is the obvious one between
the townspeople and the German armies. Another is the uncertainty within the German army
itself, which contains cruel men (SS men, whom the townspeople call “Ludwig”) and the
young occupiers (men of the German army, called “Fritz”). But the young occupiers and
the natives treat each other as friends, so that the major conflict ultimately centers
on the character and choices of a young German soldier actually named Fritz. He seems no
older than sixteen, and has become close to the narrator’s family despite the hostility
of the narrator’s father, who claims that Fritz is “the enemy” (paragraph 6). He
regularly visits the house, brings rations to the family, describes his home in Germany,
and explains his feelings of homesickness. When the narrator hurts his knee, it is Fritz
who provides first aid. In short, Fritz represents one of war’s major ironies: Warfare
puts people into opposing roles even though they have a greater common interest to be
friendly and helpful.
