Answer: Beowulf and warriors from Geatland
Step-by-step explanation:
This is most probably based on the story of Beowulf.
In it, Beowulf, a brave and strong warrior, hears that the people of Denmark were being terrorised by a monster named Grendel who attacked and killed some of them at night.
Beowulf set sail for Denmark to fight the monster and save the people from its tyranny. In his ship were 15 warriors (including himself) and when they landed in Denmark, the Coast guard remarked on how well armed and composed they were.
