Please give three examples of foreshadowing that occur in "The Sniper."

Foreshadowing, or the deliberate planting of hints as to
what will come later on in the novel, is a deliberate strategy that is used very
successfully by Liam O'Flaherty in this excellent short story. Continually foreshadowing
is used to point towards what happens later on in the story. One of the first examples
comes when the protagonist decides whether to risk smoking or
not:

He paused
for a moment, considering whether he should risk a smoke. It was dangerous. The flash
might be seen in the darkness, and there were enemies
watching.

This of course
foreshadows the first bullet that is fired at him when he lights the cigarette, which
reinforces the position of danger that he is in.

We could
also say that the initial description we are given of the sniper foreshadows the
killings that he commits. Consider that we are told his eyes "had the cold gleam of the
fanatic." In addition, we are told that his eyes are the "eyes of a man who is used to
looking at death." This of course foreshadows the ease and coldness with which he kills
both an informer, a soldier, and his anonymous opponent on the roof opposite
him.

Lastly, the most important example of foreshadowing in
the story comes when he has triumphed over his mystery opponent on the opposite roof and
instead of feeling happy, is overwhelmed by disgust and
fear:

His
teeth chattered, he began to gibber to himself, cursing the war, cursing himself,
cursing everybody.

This of
course foreshadows the most traumatic revelation of the story; that the identity of his
opponent is actually his brother.
