In the aftermath of the battle of Dingestow New Radnor Castle was seized by the sons of Einion Clud of Elfael. Einion o'r Porth and Rhys ap Gruffydd of Deheubarth entertained Baldwin of Exeter, Archbishop of Canterbury and Giraldus Cambrensis here in 1188 during their famous tour of Wales recruiting for The Crusades. Einion was killed by his brother in 1191 and in 1195 Matilda de St Valery was probably responsible for retaking the castle for her husband William de Braose. As a result, the previous overlord Rhys ap Gruffydd returned and sacked the castle before winning the battle of Radnor against Roger Mortimer and Hugh de Say.
