Afer this conquest, and that the earl of Derby had left there men at arms and archers, he came before Bonneval1, and made a violent attack upon it, in which many were killed and wounded. At last he took it, and showed mercy. After he had reinforced it with men at arms, and another governor, he pushed forward, and, entering the county of Perigord, passed by Bordelles2, but did not attack it, as he saw it would be only pains thrown away. He still advanced, until he came before Perigueux3. There was in the town the earl of Perigord, the lord Roger de Perigord his brother, the lord of Duras, and fully six-score knights and squires of that country. When the earl of Derby came there, he considered in what manner he might attack it most advantageously, for he saw it was very strong. But, after having maturely weighed it, he thought it most prudent not to waste his time: he therefore retreated two leagues, and took up his quarters upon the banks of a river, in order to attack the castle of Pelagrue4.
Towards midnight, about two hundred lances, well mounted, sallied out of Perigueux: they rode so fast, that before daylight they came to the English camp, and falling upon it, killed and wounded many. They entered the tent of the earl of Oxford, whom they found arming himself: he was immediately attacked and taken prisoner, as well as three knights of his household, otherwise he would have been slain. The Gascons finding they had awakened the whole army, retired, and took their road to Perigueux. It was time for them to do so: and fortunately they found the gates of the barriers open; for they were so closely pursued that they were thrown into confusion: but the Gascons, as soon as they could rally themselves, dismounted, and, sword in hand, fought with the English, and maintained their ground so well that they lost nothing.
The English returned to the earl of Derby, who marched forward until he came before Pelagrue, where he remained six days, and many an assault was made upon it. During the time he continued there, the earl of Oxford and his companions were exchanged, for the viscount de Bousquetin, the viscount de Châtillon, the lord of Lescun, the lord of Chateauneuf; and upon condition that the lands of Perigord should remain in peace for three years: not, however, but that any knight or squire might take up arms, without forfeiting the treaty; but nothing was to be burnt or pillaged in that country for that space of time. The English therefore departed from before Pelagrue, as it was part of Perigord, and rode towards Auberoche5, where there is a handsome and strong castle, appertaining to the archbishop of Toulouse. The English took up their quarters round about it, as if they meant to remain there for a length of time, and sent word to those within, that if they did not surrender speedily, when the town was taken, they should be all put to the sword without mercy. The inhabitants of the town and castle were much alarmed: and, seeing no appearance of any succour coming to them, they put themselves under the obedience of the earl of Derby, upon condition that their lives and fortunes were spared, and acknowledged him as their lord, for the king of England.
The earl then made a handsome retreat towards Bordeaux, having left in Auberoche a sufficient garrison, under the command of sir Frank van Halle, sir Alain de Finefroide, and sir John Lendal. On his road he came to Libourne, a fair and large town, twelve leagues from Bordeaux; to which he laid siege, and told those about him, that he would not quit it before he had got possession of it. The inhabitants consulted together; and considering well the good and evil of being assaulted and vexed, they surrendered themselves to the earl of Derby, and did homage to him during the three days he remained there. The earl of Derby sent the earl of Pembroke to Bergerac, and left the lord Stafford, sir Steven de Courcy, and the lord Alexander de Haulfiel6, with their men, in Libourne. He himself accompanied by the earl of Oxford and sir Walter Manny, took the road for Bordeaux, where they arrived.
