Which giant race destroys most of Odysseus's fleet by hurling rocks?

The Laestrygonians are the giant race that destroys most of Odysseus’s fleet by hurling rocks.

In Book 10 of Homer’s Odyssey, Odysseus and his twelve ships reach Telepylus, the stronghold of the Laestrygonians. The ships enter a sheltered harbor surrounded by steep cliffs, but Odysseus keeps his own vessel outside, moored to a rock.

The Laestrygonian king, Antiphates, attacks the scouts, and the giants then swarm around the harbor. From the cliffs they throw enormous stones, smash the ships, and spear the trapped sailors. Eleven of Odysseus’s twelve ships are destroyed, and most of his men are killed or eaten.

Odysseus escapes only because his ship remains outside the harbor. This episode is often confused with the Cyclops adventure, but Polyphemus attacks one ship and uses a cave, while the Laestrygonians overwhelm an entire fleet with their height, numbers, and rocky terrain. The survivors sail next to Circe’s island.
