Irony is a literary device in which the actions and the dialogues between the characters reflect a situation that is completely opposite to what happens in reality. In this excerpt, this literary device conveys the idea of how ironic or non-sense the lives of the wounded soldiers turn out to be after war because each of them lost the part of their body they used to perform the actions or tasks in which they were good. For example, one soldier was a good fencer, but his hand was hurt.
