Three great battles are sung of Beowulf’s life, the first in the hall of King Hroðgar where the celebrations angered Grendel who slew many warriors within.
Beowulf wrestled the fell creature and tore off the creature’s arm. This caused his second battle, now against Grendel’s mother. They fought in her lair under the lake and with a magic sword he beheaded her.
King Beowulf’s final battle was against a dragon enraged by a theft from its horde. All but loyal Wiglaf abandoned him and together they slew the dragon, but Beowulf was mortally wounded and buried with the cursed treasure.
