From Scotland the Legate turned to Wales. Throughout the winter of 1219–1220 he was in the west of England, negotiating with Llywelyn for the settlement of a dispute between the Welsh prince and Hugh de Mortimer about certain manors on the Welsh border.[605] On 2nd December Llywelyn was invited, or summoned, to meet the Legate at Worcester to discuss the matter on 7th January, 1220.[606] The King’s letter, however, contained a summons to answer complaints as well as to make them; and it may have been for this reason that Llywelyn was unwilling to obey it. At his request Pandulf postponed the meeting till the octave of Candlemas.[607] {1220} It seems to have had a successful result thus far, that Llywelyn was induced to refrain from open hostilities throughout the spring. On Rogation Monday, 4 May, he met the King, the Legate, the Archbishop of Canterbury, the Bishop of Winchester, and the Justiciar, in conference at Shrewsbury,[608] and gave what was understood on the English side as a promise that he would surrender the lands in dispute between himself and Hugh de Mortimer.[609] An attempt was also made to check the perennial strife between the men of the Welsh prince and those of the English Earl in Pembroke, by a truce on the understanding that the Marshal and the other Marcher lords “should be restored to their rights” before 1st August.[610] On the strength of these promises David, Llywelyn’s eldest son by Joan, was formally taken under the King’s protection, and the subject princes of Wales were bidden in the King’s name to be loyal to both Llywelyn and David.[611] [Sidenote: 1220]
