It was not the first time, nor was it to be the last, that the Welsh fled before Hubert de Burgh. He now led the King and the host from Hereford to Leominster and Shrewsbury, and thence, on the last day of September, to Montgomery,[899] passing through Llywelyn’s lands and driving the flocks and herds before them as they went, to serve for the sustenance of the troops. The castle of Montgomery, originally built by one of the most famous of the followers of William the Conqueror, had been more than once destroyed by the Welsh. Its site, which had sufficed for the simple Norman keep reared by the first Earl of Shrewsbury, was probably not suited for more elaborate fortifications such as were used in the thirteenth century; it served, however, to shelter the King and the Justiciar; and some of “the wiser men of the army,” while scouring the country around it under Hubert’s orders, found “a place fit for building a castle whose position, everyone thought, would be impregnable.”[900] Urgent orders were despatched to the sheriff of Shropshire for an immediate supply of building materials and tools, and the work was begun at once.[901] Meanwhile Llywelyn had been excommunicated by Archbishop Stephen. On 7th or 8th October, at Montgomery, the Prince once more came and made submission to King and Primate, Stephen dictating the terms. Llywelyn swore that within a reasonable time, to be fixed by the Archbishop, and in a fitting place, he would make satisfaction to the King and the King’s men for all damages done by himself and his men since the day of the taking of Kinnerley. Six lesser Welsh chieftains swore with him; each of the seven embodied his engagement in a charter; and on these conditions Llywelyn was absolved.[902] Moreover, he at once gave the King seisin of Kinnerley and Whittington, that he might restore them to their former owners; and Henry gave back to Llywelyn and his men seisin of all that they had held in fee on the day of the capture of Kinnerley, subject to a trial of counterclaims at the date fixed for Llywelyn’s promised satisfaction[903]--that date being Candlemas, 1224.[904] This conditional restitution of course did not include Cardigan and Caermarthen, which Llywelyn had held merely as custodian for the Crown. On 7th November these two castles were committed to the only man in whose keeping they were likely to be safe--the Earl Marshal.[905]
