Which lines in this excerpt from book 12 of homer's odyssey reveal that the monster scylla cannot be defeated in battle, even by a great warrior such as ulysses?

book twelve

"at sea once more we had to pass the sirens, whose sweet singing lures sailors to their doom. i had stopped up the ears of my crew with wax, and i alone listened while lashed to the mast, powerless to steer toward shipwreck. next came charybdis, who swallows the sea in a whirlpool, then spits it up again. avoiding this we skirted the cliff where scylla exacts her toll. each of her six slavering maws grabbed a sailor and wolfed him down. deathless the pest! impenetrably strong! furious and fell, tremendous to behold! e'en with a look she withers all the bold! she mocks the weak attempts of human might. finally we were becalmed on the island of the sun. my men disregarded all warnings and sacrificed his cattle, so back at sea zeus sent a thunderbolt that smashed the ship. i alone survived, washing up on the island of calypso."
