Describe Beowulf's boasts upon meeting Hrothgar, king of the Danes.

When Beowulf first speaks to Hrothgar upon arriving in the land of the Danes, he tells Hrothgar that he is qualified to fight their monster, Grendel.  He says that his people, the Geats, have seen his strength in war where he's proven himself a good fighter.  He tells of how he chased the race of giants from the earth and how he swam in the blackness of night, hunting down sea monsters and killing them one by one.  When Unferth then challenges Beowulf's abilities by asking about a swimming match with Brecca in which Beowulf supposedly lost, Beowulf answers with more tales of his abilities.  Beowulf says that no one can match his swimming abilities and during this swimming match, he kept close to Brecca until a flood forced them apart, then Beowulf was attacked by sea creatures and he had to fight them off.  One monster in particular grabbed Beowulf but he was able to kill it. Then more monsters attacked him and he had to battle and kill them.  He concludes by saying he killed nine in total.  He goes on to brag that he won't fight Grendel using any weapons since Grendel uses no weapon when he attacks. He tells Hrothgar that he will emerge victorious or die trying.
