Thus whilest both parts kept so farre from all hope of agréement, and were now in point to haue departed in sunder, through mediation of some bishops that were present a peace was concluded, and the parties so agréed, that all matters in controuersie touching the articles, prouisions, and statutes made at Oxenford should be ordered and iudged by the French king, whom they chose as arbitrator betwixt them. Herevpon, on the thirtéenth of September, both the king and quéene, with their sonnes, and diuerse other of the nobles of this land, tooke shipping, and sailed ouer to Bullongne, where the French king as then was at a parlement, with a great number of the nobles and péeres of France. The earle of Leicester also with diuerse of his complices went thither, and there the matter was opened, argued, and debated before the French king, who in the end vpon due examination, and orderlie hearing of the whole processe of all their controuersies, gaue express sentence, that all and euerie of the said statutes and ordinances deuised at Oxford, should be from thencefoorth vtterlie void, and all bonds and promises made by king Henrie, or anie other for performance of them, should likewise be adnihilated, fordoone, and clearelie cancelled. [Sidenote: An. Reg. 48.] [Sidenote: _Matth. Westm._] The barons highlie displeased herewith, refused to stand to the French kings award herein, bicause he had iudged altogither on the kings side. Wherevpon after they were returned into the realme, either partie prepared for warre: but yet about the feast of S. Edward, the king and the barons eftsoones met at London, holding a new parlement at Westminster, but no good could be doone. Then when the king of Almaine and prince Edward, with others of the kings councell saw that by rapine, oppression, and extortion practised by the barons against the kings subiects, as well spirituall as temporall, the state of the realme and the kings honour was much decaied, and brought in manner vnto vtter ruine, they procured the king to withdraw secretlie from Westminster vnto Windsore castell, of which his sonne prince Edward had gotten the possession by a traine. From Windsore he went to Reading, and from thence to Wallingford, and so to Oxford, hauing a great power with him. [Sidenote: The lords that reuolted to the king.] At his being at Oxford there came vnto him the lord Henrie, son to the king of Almaine, Iohn earle Warren, Roger Clifford, Roger Leiborne, Haimond le Strange, and Iohn de Vaux, which had reuolted from the barons to the kings side, Iohn Gifford also did the like: but he shortlie after returned to the barons part againe. The kings sonne the lord Edward had procured them thus to reuolt, promising to euerie of them in reward by his charter of grant fiftie pounds lands to aid the king his father and him against the barons.
