How does Odysseus escape Circe's island?

and this is basically what happens

"After I defeated the Trojans, I headed home to the people, children and wives of Ithaca. Little did I know, I had been forsaken by Poseidon the mythical Greek god of the sea, whose anger knew no bounds! I met cyclopes and giant beasts who had the potential to eat at least six of my men and creatures who could swallow entire oceans. I met witches like Circe and Calypso, and met princesses like Naucissa. I was helped by the wind keeper and I had to travel to the land of the dead! Finally I made it home and still I met adversity. My son had been mistreated, my house desecrated and my wife harassed by many suitors. It did not matter though, none of them could defeat me and I finally was able to hold my wife Penelope in my arms" Odysseus-Conqueror of Troy
