The town, when such protection was necessary, was surrounded by a wall, flanked with towers, and fit to resist and repulse an army of besiegers; but these warlike appendages, like those who built them, have passed away, and left behind them little more than the tradition of their massive strength and number. The towers, as well as the castle, were the work of Fitz-Hamon, who, as already noticed, possessed himself of Glamorganshire at the close of the eleventh century, and divided the spoils among his retainers. The following account of his expedition--somewhat different from the chronicle above quoted--is from Caradoc of Llancarvan:[387]--About the same time also died Cadifor, the son of Calhoyn, lord of Dyfed, whose sons, Llewellyn and Eineon, moved Gruffydh-ap-Meredith to take up arms against his sovereign prince, Rhys-ap-<g>Twdor</g>, with whom they joined all the forces they could levy among their tenants and dependants; and then passing with their army to Llandydoch, boldly challenged Rhys to fight; who thereupon gave them battle, and after an engagement, maintained with great resolution on both sides, the rebels were at length put to flight, and so closely pursued that Gruffydh was taken prisoner, and executed as a traitor. But his brother Eineon making his escape, and not daring to trust himself to any of his kindred, fled to Jestyn-ap-Gurgant, lord of Morgannwe, then in actual rebellion against <g>Prince Rhys</g>. And, to ingratiate himself the more in Jestyn’s favour, he promised, on the performance of certain articles--one of which was, that he should receive his daughter in marriage--that he would bring over to his aid a considerable body of Normans, with whom he was intimately acquainted, from the fact of his having served with them in England. These articles being agreed to, Eineon hastened across the frontier, and soon prevailed on Fitz-Hamon and his knights to take up the cause of Jestyn. Early in the spring they arrived in Glamorganshire, and joining Jestyn marched with their combined forces into the dominions of Prince Rhys, where, without the least show of mercy to his countrymen, <g>Eineon</g>, by his own example, encouraged the Normans to destroy all that came before them. The prince, then more than ninety-eight years of age, and sadly grieved to find his people and territory so unmercifully harassed, speedily raised an army and marched against the invaders. They met near Brecknock, and there, after a most sanguinary engagement, the venerable prince fell at the head of his army, and left his country a prey to Norman domination. Having discharged their stipulated service, and received the promised reward, <g>Fitz-Hamon</g> and his army prepared to embark for England. But before they set sail, Eineon made his complaint that Jestyn had ungratefully affronted him, and absolutely refused--now that the Normans were dismissed--to make good the conditions previously agreed upon
