Beowulf is very courageous. Even though he knows that Grendel has killed many men who tried to slew him, Beowulf, nonetheless, volunteers to fight and kill Grendel. Beowulf says, Now I mean to be a match for Grendel, settle the outcome in single combat (Heaney 29). Hrothgar shows his confidence in Beowulf. In this scene, as Beowulf volunteers to take on Grendel, Hrothgar shows his confidence by putting Beowulf in charge of his hall. Hrothgar says, Never, since my hand could hold a shield have I entrusted or given control of the Danes' hall to anyone but you (Heaney, 45).
The beast is dead!
Grendel is cowardly. He eats men in their sleep rather than fight them directly. The story describes the scene, He saw many men in the mansion, sleeping, a ranked company of kinsmen and warriors quartered together. And his glee was demonic, picturing the mayhem: ... (Grendel) struck suddenly and started in; he grabbed and mauled a man on his bench, bit into his bone-lappings, bolted down his blood and gorged on him in lumps, leaving the body utterly lifeless, eaten up hand and foot (Heaney, 51).
Take this sword as token of my graditude.
Grendel's cowardice is further shown by his fight with Beowulf. The book says, Every bone quailed and recoiled, but he could not escape (Heaney, 51). His actions during his fight with Beowulf also prove that he is not only cowardly, but weak compared to the strength of the man who is his match. This scene also demonstrates Beowulf's strength. The story describes how Hygelac's kinsman kept him helplessly locked in a handgrip (Heaney 55). Not only does Beowulf manage to keep Grendel in this handgrip, but he also rips off Grendel's arm and drives Grendel to his death.
Hrogthar shows his gratitude to Beowulf for slaying Grendel. He gives Beowulf, among other things, a sword carried high, that was both a precious object and a token of honor (Heaney, 69).
