What does Odysseus do to defeat Polyphemus?

To defeat Polyphemus, Odysseus devises a clever plan. He first gets the Cyclops drunk with wine and then tells him his name is "Nobody." When Polyphemus falls asleep, Odysseus and his men blind him by driving a sharpened stake into his eye. When the other Cyclopes come to his aid, Polyphemus calls out that "Nobody" is hurting him, allowing Odysseus and his men to escape undetected.
