The setting of In another country is Italy, a country that underwent thousands of casualties in the war. This country becomes the Objective Correlative for the title´s figurative “another country” in which the wounded soldiers find themselves.
The narrator says: “In the fall the war was always there, but we did not go to it anymore.”
Figuratively the soldiers are in another country, alienated from other people and from the war.
Ah is an interjection because an interjection is an abrupt remark.
