In the island of Circe, Odysseus' men are turned into pigs by the enchantress Circe. With the help of Hermes, Odysseus resists her magic and convinces her to turn his men back into humans. Odysseus and his crew then stay on the island for a year, enjoying Circe's hospitality before continuing on their journey.
He doesn't escape, he's let go. After Zeus says it's time to send Odysseus home, he describes what will happen on this last leg of the journey. Then, he send Hermes to tell Calypso it's time to send Odysseus away. She gives Odysseus some tools, they go into the forest and he builds himself a ship. She gives him some cloth, he makes sails. She supplies him and send him on his way.
She thinks Odysseus will forget about his home and family and stay with her.
