What does Polyphemus ask Poseidon?

He begged his father to make Odysseus's journey back to Ithaka either impossible, or extremely difficult if it was Odysseus's destiny to go back home. Polyphemus begs his father to make him return under strange sail, meaning that he'll come back as a stranger in which nobody will recognize. He begs his journey will be full of misery and death, and that he will return home with NOBODY left (all his crewmen will die).
