What does Beowulf fight in his last battle and why?
Beowulf kills Grendel’s mother in her underground lair. To avenge the death of her son, Grendel’s mother kills one of Hrothgar’s highest advisers. When Beowulf hears of this, he follows her back to the swamp where she lives and kills her in an epic underwater battle. Finding the corpse of Grendel where the mother has stored it, Beowulf cuts off the head of Grendel and gives it to Hrothgar as a battle trophy.
