In less than three years the whole arrangement was again destroyed. David, though he had fought for Edward and been well rewarded, suddenly deserted to his fellow countrymen. He attacked the Castle of Hawardyn, and, in company with his brother Llewellyn, besieged Rhuddlan and Flint. Edward at once advanced against them. Hard pressed, the brothers divided their forces. David continued to fight in the North, while his brother betook himself to South Wales. He was there surprised, defeated, and killed, on the River Wye, and his head sent to Edward, and displayed in London, in scorn adorned with an ivy crown, in allusion to some prophecy that he should be crowned in London. David was shortly afterwards compelled to surrender. A Parliament had been summoned to grant supplies; some difficulty had arisen, and before an answer could be given, a fresh one was called at Shrewsbury, (moved afterwards to Acton Burnell, the seat of the Chancellor,) by which the unfortunate Prince was tried, and condemned to death. This Parliament afterwards proceeded to the settlement of the conquered country, by what is known as the Statute of Wales. By this a considerable part of English law and English institutions, with some modifications to suit the prejudices of the Welsh, were introduced. The conquest was completed by the famous presentation to the people of the King’s new-born heir, under the title of the Prince of Wales. There was henceforth no longer any pretence of feudal supremacy; Wales was annexed to the English Crown. The following year the Parliament at Winchester produced the Statute known by the name of that city, which arranged the defence of the country upon a national basis. Of that piece of legislation, as well as of others before and after it, more will be said by and by. In the year after this, Edward left England, placing the government in the hands of his brother Edmund. [Sidenote: Foreign affairs call Edward abroad.] [Sidenote: Sicilian Vespers.]
