Ambiguity in “The Sniper”

Ambiguity in the short story “The Sniper” is seen in Liam O’Flaherty’s writing. At the end of this story, O’Flaherty writes “The sniper turned over the dead body and looked into his brother’s face”. In this quote, “brother” could be signified as many different meanings. When you first read the story you get the feeling that the man the sniper shot was his true blood brother. As you continue thinking, the “brother” could be a man or a friend on the same side as he is on and he accidentally shot him in hesitation.
