How did Scylla kill the 6 men?

Scylla killed the six men by snatching them from Odysseus's ship as it passed through the strait between her and Charybdis. As the ship approached, she emerged from her lair, her twelve dog-like heads snatching the sailors one by one. Despite Odysseus's attempts to save them, the men were powerless against her fearsome grasp. This encounter exemplified the perilous challenges he faced during his journey home.
