“The Sniper” emphasizes one of the greatest ironies of civil war: Brother is pitted against brother. In this story, Liam O’Flaherty deals with a strife that has divided Ireland for more than sixty years and still shows few signs of moderating. The Republican sniper in the story is young, and his youth is emphasized. However, under conditions of war, this youth is growing up fast, probably too fast. He has the look of a fanatic, and he is forced to develop the cunning of a seasoned warrior. If he fails to develop that cunning, he will not live.
In the course of two hours, the young sniper kills three people, one his own brother—who, ironically, is poised to kill him if he is given the opportunity. The Republican sniper outwits the Free Stater into being careless, and this carelessness costs the Free Stater his life.
In a sense, carelessness also costs the man in the turret of the armored car his life. He should not have responded to the old woman who came to give him information. Had he not exposed his head, he could not have been killed, because the car’s armor would have protected him. In a moment of relaxed security, he makes himself vulnerable and loses his life. In the next instant, the sniper kills an old woman.
O’Flaherty demonstrates the impersonality of war: One shoots the Enemy, not people. When the sniper is doing his killing, it is the Enemy at whom he is firing. The Enemy, however, becomes a person when the protagonist sees the opposing sniper’s body fall to the ground. He is sickened at the thought of what he has done, and one can only speculate on the implications for him of discovering, ultimately, that it is his own brother he has killed.
O’Flaherty is saying that soldiers grow up fast or not at all. There is no question that the sniper does what he has to do, and at the beginning, there is a great adventure in what he is doing. The adventure, however, depends on anonymity. No one in this story has a name, and everyone, even, to an extent, the protagonist, is seen from a distance. Once one is killing people, the whole impact of what war is about crowds in on the killer.
Although one perhaps cannot go so far as to call “The Sniper” a pacifist tract, certainly it depicts several of the worst horrors of war. It shows that war makes life seem cheap. It shows that war also hardens the hearts of those who participate in it. In the end, the story shows the absurdity and futility of fighting against individual human beings.
Both snipers in this story are pawns of forces larger than themselves, and these forces split families, shatter loyalties, and pervert the very causes that they purport to be fighting to preserve. The first irony is that men will kill other men. The second and greater irony in the O’Flaherty story is that in this case the two men are of the same parents.
