Three Unhappy Blows of the Island of Britain

The Three Unhappy Blows of the Island of Britain is a framing concept that places the injury inflicted on Branwen within a larger sequence of national calamities. The narrative calls her mistreatment the third unhappy blow: a grievance first imposed on one woman becomes the occasion for a reckoning between kingdoms, and the account closes by linking that injury to both revenge and a long aftermath.

The Injury and Its Causes

The immediate cause of Branwen’s punishment is unrest in Ireland during the second year after her arrival. Matholwch’s foster-brothers and closest supporters openly blame him for the insult he had received in Cambria and for the payment made over his horses. They demand revenge for the disgrace, and the vengeance falls on Branwen: she is removed from the chamber she shared with Matholwch and made to cook for the court. Each day, after the butcher has cut up the meat, he strikes her on the ear. The repeated blow makes the punishment bodily and routine, while its cause lies in a political dispute for which Branwen is made to suffer.

Suppression and Witness

Matholwch’s men urge him to close the routes between Ireland and Cambria: ships, ferry boats, and coracles are forbidden to travel, and people arriving from Cambria are imprisoned to prevent news of Branwen’s treatment from getting back. The restriction lasts no less than three years. Against this enforced silence, Branwen raises a starling beneath the cover of a kneading trough and teaches it about her brother, Bendigeid Fran. She writes an account of her woes and the contempt with which she is treated, ties it to the root of the bird’s wing, and sends it toward Britain. At Caer Seiont in Arvon, the starling alights on Bendigeid Fran’s shoulder; its domestic upbringing helps those present recognize that it has come from human company. The small bird carries the testimony that the blocked sea routes were meant to suppress.

Retaliation and Narrative Frame

The Mabinogi’s concluding account names Branwen’s injury as the third unhappy blow of the island and describes the response as an expedition to avenge it: the hosts of “sevenscore countries and ten” go to Ireland. Its summary also holds that retaliation alongside the seven-year banquet at Harlech, the singing of the Birds of Rhiannon, and the head’s sojourn for fourscore years. The injury therefore marks more than the moment of Branwen’s abuse. It supplies the grievance that frames the campaign and stands at the beginning of a story whose ending lingers on extended feasting, song, and the long keeping of Bendigeid Fran’s head.
