Answer: When the Chorus Leader discusses the fate of "that pair of wretched men", he refers to Eteocles and Polynices, the brothers of Antigone and Ismene.
Step-by-step explanation: In the play Antigone by Sophocles, the conflict partly starts when Eteocles and Polynices, the brothers of Antigone and Ismene, kill each other after fighting for the throne of Thebes. In that way, when the Chorus Leader uses the phrase "that pair of wretched men" in the middle of the account of Thebes' civil war, he is referring to the brothers Eteocles and Polynices.
