Here's a breakdown of the factors contributing to Beowulf's success:
* Beowulf's physical strength and fighting prowess: He is described as incredibly strong, skilled in combat, and fearless. He uses his strength and skill to overcome Grendel and his mother in hand-to-hand combat.
* Beowulf's divine favor: The poem suggests that Beowulf is favored by God. He is described as a "God-sent hero" and his victory is often attributed to divine intervention.
* The limitations of Grendel and his mother: Grendel and his mother are monstrous creatures with supernatural powers. However, they are ultimately defeated because they are vulnerable to human weapons and Beowulf's superior strength.
* The role of fate: The poem also suggests that fate plays a role in the outcome of the battles. Beowulf's destiny as a hero is woven into the narrative, leading him to confront the monsters and emerge victorious.
The poem does not mention any specific "defeat" attributed to Grendel or his mother. Instead, it focuses on Beowulf's triumph and the factors that contributed to his success.
