What would water and fire do to the Nazgul?

[Thingol]

I don't know about them being physically impotent, Sharku. The Witch King shatters a shield with his mace and breaks Éowyn's arm in the process. To actually shatter a shield requires a tremendous amount of strength (my uncle has one [img]smilies/biggrin.gif[/img]) I've always thought the reason the Ringwraiths retreated was because they believed that Frodo could not hold out against the wound from the Morgul blade and they wanted the ring bearer to suffer before they took him. I do not envision much fighting in the scene, let alone the Nazgul actually being driven off by Aragorn. I did not like the movie portrayl at all, I've always believed that the Nazgul chose to retreat. Perhaps they were afraid of being robbed of their raiment or even being slain by Aragorn and they did not want to take a chance. It is easy to underestimate the power of the Ulari, but remember Gandalf says that not even Glorfindel (a very, very powerful elf that killed a Balrog) and Aragorn could stand against the 9 alone.
