In Book 9 of the Odyssey, Odysseus tells the Cyclops that Poseidon, who is the Cyclops's father, "smashed my ship/he drove it against the rocks at your island's far cape" (lines 319-320). Part of the reason that Odysseus lies to the Cyclops is that the holds of his ship are filled with provisions that his men took from the Cicones' holy city, including "generous store in jars" (line 183). Odysseus wants to protect his stores from the Cyclops. In addition, Odysseus wants to be able to escape from the Cyclops's lair. At the end of Book 9, Odysseus slaughters the Cyclops's sheep and leaves with his remaining men on their ships, and the ships are critical to the survival of the men who the Cyclops has not killed. Odysseus blinds the Cyclops in order to escape, and Poseidon, the Cyclops's father and god of the sea, makes it difficult for Odysseus to return home in his boat.
