What happens when Beowulf first arrives on the shore of Hrothgar's lands

Once they reach the shore, they depart the ship with their armor and weapons clinking. A coast watchman stops their progress, demanding to know who these warriors are and if they are friend or foe. It isn't until introductions are made that Hrothgar welcomes Beowulf as the son of Ecgtheow, the man whom Hrothgar had helped in settling a feud with the Wylfingas long ago. THen there is much celebration.
