Arrange the following events in order first to last based on when they occurred in the story Beowulf?

To arrange events in "Beowulf," we start with Beowulf’s arrival in Denmark to help King Hrothgar, followed by his battle with Grendel, then the defeat of Grendel’s mother, and finally, Beowulf’s return to Geatland, where he eventually becomes king and faces the dragon in his final battle. Each of these events builds upon the previous ones, illustrating Beowulf's heroic journey and the themes of bravery and legacy.
