King John and Matilda de Braose were real, but their personal relationship, if any, is a matter purely of surmise. That she goaded him about the murder of his nephew and, on more than one occasion, provoked him to outbursts of fury, is recorded. Matilda’s affair with Richard de Clare is purely imaginary, as is my speculation as to the possible illegitimacy of any of her children.
The circumstances surrounding the death of young William and Matilda are mysterious, but the chronicles are more or less unanimous in saying that John deliberately had them starved to death, either at Corfe or at Windsor Castle.
The king’s actions have never been satisfactorily explained, even though his patience must have been considerably strained by William’s behavior. The viciousness of his treatment of Matilda and Will caused such an outcry at the time, when cruelty and revenge were commonplace, that the king himself felt it necessary later to issue a statement explaining the course of events leading up to the outlawry of William senior. The death of the two hostages he could not or would not explain, but his statement was signed by various friends of Matilda and relatives, including Adam de Porter, Earl Ferrers, and the Earl of Clare himself.
There were two generally accepted reasons put forward to explain John’s behavior: one, that Matilda had unforgivably taunted the king about the murder of Arthur of Brittany, and the other that John had decided anyway to make an example of a rich and powerful baron and selected the brash upstart William for the role. It is possible that when he had eventually to carry out the sentence of death against the hostages he could not bring himself openly to order execution.
For whatever reason, the downfall of the de Braose family, if it was intended to intimidate other powerful nobles, succeeded in achieving the opposite effect. It scandalized the country and the signatories of John’s statement were among those who, four years later, signed Magna Carta, with its famous clause 39, which stated:
No man shall be taken, imprisoned, outlawed,
banished or in any way destroyed, nor will we
proceed against or prosecute him, except by
the lawful judgment of his peers or by the law of the land
William de Braose died in exile in France on 9 August 1211. His funeral service was conducted by Stephen Langton and he was buried in the Abbey of St. Victor in Paris.
Giles, Bishop of Hereford, returned from exile in France in 1213, ostensibly ready to make his peace with the king, but when John showed no signs of returning to him the confiscated de Braose lands, Giles sent his brother Reginald to the Marches, and eventually the castles of Abergavenny, White Castle, Skenfrith, Brecknock, Hay, Radnor, Builth, and Blaen Llynfi were recaptured by the de Braose family with the help of the Welsh. Reginald’s wife, Gratia de Burgh, had two children, William and Matilda, and died young. He then married Gwladys, a daughter of Llewelyn, allying himself to the Welsh, who supported the de Braoses in their efforts to regain their lands. Painscastle returned to the Welsh and was held by Gwallter, the son of Einion Clud.
Giles died in 1215 and the following year the new king, Henry III, at last recognized Reginald as inheritor of the de Braose estates.
Margaret and Mattie were released unharmed. Mattie returned to her father, Richard de Clare, who until his death held the wardship of her eldest son, John, although her sons were technically kept hostages until January 1218. John later married Margaret, another daughter of Llewelyn, and challenged his uncle Reginald’s right to the family estates.
Richard de Clare died in the autumn of 1217.
Matilda’s eldest daughter, the young Matilda, died on 29 December 1211 at Llanbadarn Fawr and was buried, as she wished, next to her husband at Strata Florida.
Of Isobel Mortimer little is known. Her husband, Roger, died in June 1214 and was succeeded by his son, Hugh.
Margaret de Lacy was still living in 1255. She had three children, Egidia, Katherine, and Gilbert.
Three carucates of land in the Royal Forest of Aconbury were cleared at Margaret de Lacy’s order, and there was founded, sometime before 1218, a rich Augustinian convent and chantry chapel to commemorate, in perpetuity, the souls of Margaret’s parents and her brother Will.
All that remains today of the priory on John’s gift of land is a small, redundant, haunted church, locked and used as a store.
