Beowulf killed Grendel by ripping off his arms. Beowulf is an old epic poem wherein Beowulf travels with fifteen warriors to accompany him in the ship on his journey to Hrothgar. King Hrothgar then asked Beowulf to get rid of Grendel who was a monster – often referred to or describe as a sceadugenga and always lurked in the dark – haunting Hrothgar’s great hall, Herot or Heorot. Beowulf and his men pretended they were asleep and when Grendel arrived, he killed one of Beowulf’s men by tearing him to pieces and drinking his blood before he attacked Beowulf himself. During their battle, Beowulf ripped off Grendel’s arms and the monster swam back in the swamp where he died from blood loss.
