[447] Gir. Cambr. as above (p. 229). The circumstances of Fitz-Stephen’s enlistment illustrate the condition of South-Wales at this time. He had been cast into prison three years before by his cousin Rees, and at the moment of Dermot’s arrival had just been released on condition of joining Rees in an attack upon England. His Norman blood, however, was loyal enough to revolt against the fulfilment of the condition; and Rees, who had warmly espoused Dermot’s interest, was persuaded to allow its exchange for service in Ireland. _Ibid._; cf. Anglo-Norm. Poem (Michel), pp. 19, 20. For pedigree of Nest’s descendants see Mr. Dimock’s edition of _Gir. Cambr. Opp._, vol. v. App. B. to pref., pp. c, ci. [448] Anglo-Norm. Poem (Michel), p. 21. [449] About August 1, according to Gir. Cambr. _Expugn. Hibern._, l. i. c. 2 (Dimock, vol. v. p. 229). [450] Four Masters, a. 1167 (O’Donovan, vol. ii. pp. 1165–1167). Among the slain they mention “the son of the king of Britain, who was the battle-prop of the island of Britain, who had come across the sea in the army of Mac Murchadha.” This can only mean a son or brother of Rees; but neither Gerald nor the Welsh chronicles make any mention of such a person in Ireland. [451] The modern county of Wexford, or rather the diocese of Ferns. The Four Masters (as above, p. 1165) say that Dermot “returned from England with a force of Galls, and he took the kingdom of Ui-Ceinnsealaigh.” [452] Gir. Cambr. _Expugn.
