Polyneices retired from Thebes
while Oedipus was still alive and reigning, in fear lest the curses of the father should be brought to pass upon the sons. He went to Argos
and married a daughter of Adrastus, but returned to Thebes
, being fetched by Eteocles after the death of Oedipus. On his return he quarrelled with Eteocles, and so went into exile a second time. He begged Adrastus to give him a force to effect his return, but lost his army and fought a duel with Eteocles as the result of a challenge.
