king has warned Beowulf of the frightful danger of sleeping in the hall.
But Beowulf lies down with his warriors, saying proudly that, since weapons
will not avail against the monster, he will grapple with him bare handed
and trust to a warrior's strength.

Forth from the fens, from the misty moorlands,
Grendel came gliding--God's wrath[5] he bore--
Came under clouds, until he saw clearly,
Glittering with gold plates, the mead hall of men.

At the sight of men again sleeping in the hall, Grendel laughs in his

first grip. Suddenly a wide wound opens in the monster's side; the sinews
snap; the whole arm is wrenched off at the shoulder; and Grendel escapes
