Laestrygonians
In the Odyssey, the Laestrygonians were giants living in the city of Telepylus. The city had an excellent harbour, with cliffs surrounding the harbour and only a narrow channel for a ship or two to sail through.
Their leader was Antiphates, king of the Laestrygonians. Antiphates and his wife were of giant size, but their daughter wasn't so tall, so the men of Odysseus didn't suspect anything unusual until they met the girl's parents.
When eleven of Odysseus' ships entered the harbour of Telepylus, the Laestrygonians attacked them, destroying the ships by hurling large rocks. They used great long spears like fishes, before devouring them.
