Isolation imposed
Matholwch’s people make Branwen a servant and strike her daily. Ships and small boats are forbidden to carry news to Britain.

Rescue made visible
The Irish see a moving forest and mountain on the sea. Branwen identifies the fleet and her brother, whose immense stature makes him impossible to mistake.
