What happens between the battle of grendel an Beowulf?

Beowulf and his men spend the night in Heorot. After they fall asleep, Grendel enters the hall and attacks, devouring one of Beowulf's men. But Grendel dare not touch the throne of Hroðgar, because he is protected by the almighty God. Beowulf, feigning sleep, leaps up and grabs Grendel's arm in a Wrestling hold, and the two battle until it seems as though the hall might fall down due to their fighting. Beowulf's men draw their sWords and rush to his help, but their sWords break upon Grendel's arm because he has put a charm on all human weapons. Finally, Beowulf tears Grendel's arm from his body at the shoulder and Grendel runs to his home in the marshes to die.
