Odysseus escaped from the Cyclops by tricking it after blinding it with a large pike. Once the Cyclops was blind, Odysseus and his men escaped by tying themselves to the bottom of the Cyclops' sheep. The monster felt the tops of the sheep but didn't check the bottoms before letting them out of the cave to pasture.
While trapped in the Cyclops' cave, Odysseus lost six men because the Cyclops killed and ate them. On the second night in the cave, Odysseus gave the Cyclops wine. Once the Cyclops had passed out, the men blinded it with a sharp pike they'd made and heated in the fire.
