Not long after they reached that city the Cardinal of Perigord and another legate presented themselves to arrange peace, and these negotiations went on throughout the winter. The prince had received full powers from his father, and his demands were very moderate; but in spite of this no final peace could be arranged, and the result of the conference was the proclamation of a truce, to last for two years from the following Easter. During the winter immense numbers of the prisoners who had gone at large upon parole, came in and paid their ransoms, as did the higher nobles who had been taken prisoners, and the whole army was greatly enriched. At the end of April the prince returned to England with King John. The procession through the streets of London was a magnificent one, the citizens vying with each other in decorating their houses in honour of the victor of Poitiers, who, simply dressed, rode on a small black horse by the side of his prisoner, who was splendidly attired, and mounted on a superb white charger. The king received his royal prisoner in state in the great hall of his palace at Westminster, and did all in his power to alleviate the sorrows of his condition. The splendid palace of the Savoy, with gardens extending to the Thames, was appointed for his residence, and every means was taken to soften his captivity. During the absence of the Black Prince in Guienne the king had been warring in Scotland. Here his success had been small, as the Scotch had retreated before him, wasting the country. David Bruce, the rightful king, was a prisoner in England, and Baliol, a descendant of the rival of Robert Bruce, had been placed upon the throne. As Edward passed through Roxburgh he received from Baliol a formal cession of his rights and titles to the throne of Scotland, and in return for this purely nominal gift he bestowed an annual income upon Baliol, who lived and died a pensioner of England. After Edward's return to England negotiations were carried on with the Scots, and a treaty was signed by which a truce for ten years was established between the two countries, and the liberation of Bruce was granted on a ransom of 100,000 marks.
