Beowulf's sword fails him when he attempts to use it to defeat the dragon, but the blade shatters upon striking the dragon's scales, proving ineffective against the powerful monster.
In sections XIX-XXI of Beowulf, the main plot points are: Beowulf prepares to fight the dragon to protect his people, he faces the dragon alone as his warriors retreat in fear, Beowulf's sword fails him in battle, and Wiglaf comes to his aid, helping Beowulf defeat the dragon but also getting wounded in the process.
In Beowulf's battle with Grendel, he fails to defeat him with weapons, resorting instead to using his bare hands. In his battle with Grendel's mother, he fails to kill her with his sword, Hrunting, and relies on a magical weapon instead. Finally, in his battle with the dragon, Beowulf is mortally wounded as his sword breaks, resulting in his death.
Beowulf did not fight a great fire dragon. He went against a scaly dragon of the abyss, which he beheaded, but then he slayed the creatures mother after its serious of deaths. Beowulf himself eventually leaves the city before being crowned king, against his wishes.
The sword given to Beowulf by Unferth, called Hrunting, is significant because it represents a symbol of trust and honor. It also highlights Beowulf's bravery and skill as a warrior, as he is able to defeat Grendel's mother despite the sword's initial failure to harm her.
When Beowulf swung his sword at Grendel's mother's head, the sword failed to penetrate her skin due to the enchantment that protected her. This encounter led Beowulf to realize that he needed a different weapon to defeat her.
well at first unferth calls Beowulf a poppycock hero and that he wont defeat grendel, but that's because he was drunk, after Beowulf defeats grendel then unferth apalogizes to Beowulf and gives him a sword.
Beowulf's sword is useless against Grendel's mother because her skin is too tough for it to penetrate. The sword shatters upon impact, leaving Beowulf vulnerable in the battle. Ultimately, it is Beowulf's strength and willpower that allow him to defeat Grendel's mother.
