Greenblatt explains that this relationship is based solely on mutual respect, contrasting with the reality of most relationships in armies of the time where relationships were based on subordination and grade structure.

It is the duty of the warrior to swear allegiance to his lord, but not as if he were to serve as the lord's servant but as a confidant. As the king's men prove their loyalty in battle, the king's duty is to reward them with riches in exchange for their bravery. In the poem, Hrothgar rewards Beowulf with gifts and treasure for defeating Grendel and his mother.
