What is the plot of "Soldier's Home"?

The plot of "Soldier’s Home" involves Krebs as the
protagonist in conflict with the abstract antagonism of peacetime adjustment. Obviously,
those around him expect him to be the little boy he was, and to be unchanged by the war.
They therefore assume that he can begin life again as though nothing has happened. The
crisis of the story is his conversation with his mother, and the climax is his promise
to be a good boy for his "Mummy" (paragraph 86). This portion of the story indicates
that his disaffection is approaching total alienation. The resolution, in his decision
to go to Kansas City and in his going to watch his sister play ball, suggests a
compromise with his disaffection. Though he will continue to feel like an outsider, in
other words, he will keep his misgivings to himself, and will fit in, at least
externally, with life at home.
