Odysseus raises the moral of crew as they follow one of two paths leading to the monster Scylla and Charybdis. Against Circe’s instructions Odysseus puts on his armor and waits for Scylla to attack to save the lives of his crew, but as the crew and Odysseus were distracted by Charybdis’ raw power, she inflict dread onto the crew and that was when Scylla strikes and takes six of the best of the crew one for each head, and as they cry out for Odysseus, he is powerless to help as they are eaten in agony by Scylla.
This passage is interesting to look at for it talks about the whirlpool Charybdis as if it were alive and a woman at that. This is also where Odysseus despite being such a big shot war hero is powerless against these immortals and can’t stop them from killing off his crew.

I went round, therefore, and exhorted them man by man not to lose heart.

"'My friends,' said I, 'this is not the first time that we have been in danger, and we are in nothing like so bad a case as when the Cyclops shut us up in his cave; nevertheless, my courage and wise counsel saved us then, and we shall live to look back on all this as well. Now, therefore, let us all do as I say, trust in Jove and row on with might and main. As for you, coxswain, these are your orders; attend to them, for the ship is in your hands; turn her head away from these steaming rapids and hug the rock, or she will give you the slip and be over yonder before you know where you are, and you will be the death of us.'

"So they did as I told them; but I said nothing about the awful monster Scylla, for I knew the men would not on rowing if I did, but would huddle together in the hold. In one thing only did I disobey Circe's strict instructions- I put on my armour. Then seizing two strong spears I took my stand on the ship Is bows, for it was there that I expected first to see the monster of the rock, who was to do my men so much harm; but I could not make her out anywhere, though I strained my eyes with looking the gloomy rock all over and over

"Then we entered the Straits in great fear of mind, for on the one hand was Scylla, and on the other dread Charybdis kept sucking up the salt water. As she vomited it up, it was like the water in a cauldron when it is boiling over upon a great fire, and the spray reached the top of the rocks on either side. When she began to suck again, we could see the water all inside whirling round and round, and it made a deafening sound as it broke against the rocks. We could see the bottom of the whirlpool all black with sand and mud, and the men were at their wit's ends for fear. While we were taken up with this, and were expecting each moment to be our last, Scylla pounced down suddenly upon us and snatched up my six best men. I was looking at once after both ship and men, and in a moment I saw their hands and feet ever so high above me, struggling in the air as Scylla was carrying them off, and I heard them call out my name in one last despairing cry. As a fisherman, seated, spear in hand, upon some jutting rock throws bait into the water to deceive the poor little fishes, and spears them with the ox's horn with which his spear is shod, throwing them gasping on to the land as he catches them one by one- even so did Scylla land these panting creatures on her rock and munch them up at the mouth of her den, while they screamed and stretched out their hands to me in their mortal agony. This was the most sickening sight that I saw throughout all my voyages.
