Greatest Man of Middle-Earth??

[Keneldil the Polka-dot]

Actually, Beren did not exactly "face" Morgoth. Slunk underneath the throne is more like it.

And then cut a Silmaril from Morgoth's crown after Luthien sung him to sleep. You did note that I said with help? Beren (and Luthien) accomplished what the Noldor with all of their armies could not. One thing I forgot for my list before- Beren reclaimed a Silmaril twice: once from Morgoth, and once from the Dwarves of Novgorod after they murdered Thingol and stole it with the Nauglamir.

The fact that Luthien got Beren out of the Halls doesn't change the fact that he went and came back.

I do see the case for Hurin as well though. For single acts of heroism amongst Men, defying Morgoth to his face for years has tp be the top. Let's not forget, however, that Hurin was the one who led Morgoth to the location of Gondolin.
