The third stanza tells us Grendel tried more and more times to kill Beowulf, but he never succeeded in, because Beowulf can trust on his warriors that were straight, courageous, and wings to their lord. Warriors tried to hit the monster with their ancestral blades, but they cannot damage their enemy because their weapons had been tricked. Human armies cannot defeat the monster, because he is not an earthly creature, he has supernatural powers. The narrator dramatically underlines this last particular, as if he wanted the reader to understand the immortality of the monster (lines 31-32-33). Probably, Grendel has a skin covered with acid that rust the blade of the sword. We do not know how the fight goes on, but we can suppose Beowulf defeated Grendel. The hero is the only one that can win the monster, because he is the only one that have superpowers like Grendel.

The last stanza deals Beowulf won also this fight. I say also because this is not the first time Grendel tried to achieve his goals ( the text says “Time and again” ) so, maybe the monster Grendel is not death yet. If Beowulf represent the Good and Grendel represent the Evil, we can understand the fight is between Grendel and Beowulf, but only on the surface. The true conflict is between the Evil and the Good, and the Evil will never die (this is the reason because I think Grendel is yet alive) so this text can represent the eternal conflict by the two parts. This extract reflects the dualistic conception of the middle Ages therefore, it supports the hypothesisthat the writer was probably catholic.
