Two other matters came up for settlement at the Michaelmas session of the barons of the Exchequer and the justices at Westminster. One of these was a complaint of the Earl Marshal against the Prince of Wales. Llywelyn’s promise, or alleged promise, that the wrongs done by him to the Earl and the other Marcher-lords should be righted by Lammas Day[732] was not fulfilled; indeed, the truce made in May on the strength of that promise seems to have been broken as soon as Llywelyn returned from Shrewsbury to his own country. He asserted that the men of Pembroke refused to confirm the truce, called in help from Ireland against him, and harassed the Welsh to such a degree that at last he was obliged to bid his nephews and his other followers withdraw from the borders of Pembrokeshire to a safer place.[733] The Marshal, on the other hand, declared that the Welsh Prince “in no wise kept the terms of the peace, but brought the King’s dignity into contempt, spurning his own promises and acting quite contrary to them.” The Marshal complained to the King at Oxford, and was promised satisfaction--so far as the King could give it--in London on the morrow of S. Michael.[734] On 21st August the sheriffs of Gloucester, Hereford, and Worcestershire were ordered to be in readiness to help, with all the forces of those three shires, whichever of the King’s liegemen they should find to be the object of an attack for which Llywelyn was reported to be collecting his forces.[735] It was, however, not against any place on the border, but against “the Flemings of Rhos and Pembroke” that Llywelyn, with “most of the princes of Wales” and “a vast army,” marched on 29th August. He took by assault and burned the castles of Arberth and Gwys, burned the town of Haverford “to the castle-gate”; “and thus he went round Rhos and Deugleddyv in five days, making vast slaughter of the people of the country. And after making a truce with the Flemings until the kalends of May, he returned back happy and joyful.”[736] The terms of this truce were humiliating in the extreme; the men of Pembroke promised that they would give Llywelyn a hundred pounds, that they would not restore the castles which he had destroyed, and that they would give him a portion of the Earl’s land “to keep as on behalf of the King.” All these conditions, however, were to be subject to confirmation by the King. They seem to have been in fact extorted by means of a false representation on Llywelyn’s part that his invasion of the Earl’s lands was sanctioned and supported by the authority of the English Crown.[737] For the honour of that authority itself, no less than for his own sake, the Marshal besought the King and his Council to quash the truce, disavow all complicity in Llywelyn’s raid, and give judgement in favour of himself, at the time previously appointed, on his former complaint against the Welsh prince.[738] The judgement was probably given accordingly; on 5th
