Start with the immediate reason: survival
- Polyphemus seals the visitors in his cave and begins eating Odysseus's companions. The men are not fighting for treasure or victory at this point; they are trying to stop the killings and get out alive.
- Odysseus plans rather than charging at a much stronger enemy. Wine, a sharpened olive stake, and the false name Nobody turn one overwhelming opponent into a problem the trapped men can solve together.
- The cleanest answer is therefore practical: Odysseus hurts Polyphemus because disabling him is necessary for the prisoners' escape.

Why read it here: this accessible prose retelling is the quickest way to follow the cave, the attack, and the escape as one continuous sequence.
