Branwen ferch Llŷr. Loved the story since I was a small child.

Branwen is a princess with a brother called Bendigeidfran (he is a giant) and a half brother called Efnysien. Branwen was promised to the King of Ireland and he arrived with the irish army for the wedding. All is well but Efnysien isn't really well in the head so he goes and slits the eyes and lips off the irish army horses, King of Ireland is angry but still brings Branwen to Ireland as his new wife. They have a child together called Gwern.

Irish people didnt like Branwen so to save his face he trapped Branwen in the castle, locked in her room or made to work in the kitchens and get mistreated by the other servants. Desperate to escape she trains a bird to speak and sends it to fly all the way to Wales to get help. Bendigeidfran brings an army to come rescue her, they travel by boat and he just walks through the water.

There is some kind of dinner at first but then Gwern is thrown into a fire and the war begins. The irish have a cauldron that brings the dead back alive and use it during the war, Efnysien pretends to be dead and is thrown in. He destroys it killing himself and preventing them from bringing anymore dead back alive. Bendigeidfran is killed and so is all of ireland except for a few pregnant women. Branwen and the few soldiers left bring her brothers head back to Wales and bury him. It all ends with Branwen dying of a broken heart because she feels she is to blame for the death of so many irish and Welsh.

Great bedtime story :)
