What does the last line mean in Beowulf

Beowulf lies dead, and Wiglaf is bowed down with grief at the loss of his lord. The dragon, too, lies slain on the ground. The poet briefly commemorates the beast's end. ... He suggests that foreign warlords will be sure to attack the Geats now that Beowulf can no longer protect them.

"facing the rising sun of our new day begun

let us march on till victory is won.",

because the rising sun is a symbol of hope.
