What is the setting of the story "The Sniper"?

The story takes place in Dublin, Ireland, in June 1922. At this time, the Irish civil war has been going on for several months. The Republicans hold the Four Courts judicial building, but the Free Staters are attacking them with heavy arms.

The Sniper also takes place between the hours of dusk and dawn. Beginning as "twilight faded into night," the action of the story instantly becomes more dangerous. The sniper must conduct his battle in the dark. He has only "the dim light of the moon that shone through fleecy clouds" to see by.
