In the Old English poem Beowulf, Grendel returns to his swamp after fighting Beowulf because he has been mortally wounded. During their struggle, Beowulf grips the monster’s hand with such immense force that Grendel is only able to wrench himself free after his arm is torn off at the shoulder. Having suffered this fatal injury, the creature retreats to his home in the moors to die.1
