When Prince Edward knew that the French army lay between him and Poitiers, he took up his position on some rising ground to the south-east of the city, between the right bank of the Miausson and the old Roman road, probably on a spot now called La Cardinerie, a farm in the commune of Beauvoir, for the name Maupertuis has long gone out of use, and remained there that night. The next day, Sunday, 18 September, the cardinal, Hélie Talleyrand, called "of Périgord", obtained leave from King John II to endeavour to make peace. The prince was willing enough to come to terms, and offered to give up all the towns and castles he had conquered, to set free all his prisoners, and not to serve against the king of France for seven years, besides, it is said, offering a payment of a hundred thousand francs. King John, however, was persuaded to demand that the prince and a hundred of his knights should surrender themselves up as prisoners, and to this he would not consent. The cardinal's negotiations lasted the whole day, and were protracted in the interest of the French, for John II was anxious to give time for further reinforcements to join his army. Considering the position in which the prince then was, it seems probable that the French might have destroyed his little army simply by hemming it in with a portion of their host, and so either starving it or forcing it to leave its strong station and fight in the open with the certainty of defeat. John II made a fatal mistake in allowing the prince the respite of Sunday; for while the negotiations were going forward he employed his army in strengthening its position. The English front was well covered by vines and hedges; on its left and rear was the ravine of the Miausson and a good deal of broken ground, and its right was flanked by the wood and abbey of Nouaillé. All through the day the army was busily engaged in digging trenches and making fences, so that it stood, as at Crécy, in a kind of entrenched camp.
