Such was the pervading feeling, when (August 25, 1213) an assembly of the barons was convened at London. In one of their meetings, Cardinal Langton informed them that he had found a copy of the charter of Henry I., which was then entirely forgotten; this charter was read to the assembly, and received with enthusiasm. Another meeting was held at Saint Edmundsbury (November 20, 1214), and there each baron, laying his hand upon the altar, took an oath that he would use his efforts to force the king to restore in full vigour the charter of Henry I. They soon presented themselves at London in arms, and on January 5, 1215, they demanded from John, in a formal and positive way, the renewal of this charter, as well as of the laws of Edward the Confessor. John, terrified by their firmness, requested that some leisure might be granted to him in order to think over these demands, and accordingly his answer was deferred till Easter. During this interval, he endeavoured to introduce division among his enemies, and in the first place, wishing to conciliate the clergy, he granted them by a charter the liberty of electing their own bishops and abbots, and sent William de Mauclerc to Rome to complain of the audacity of the barons. {312} They too despatched Eustace de Vesci to Rome, to represent to the pontiff the justice and sacredness of their cause. This embassy, however, failed in its object; the Pope condemned the barons: but they were not to be intimidated from their purposes, and John, determining to make another effort in order to secure the support of the church, took the cross on the 2nd of February, 1215, and made a vow to lead an army into Palestine. The respite, however, which the barons had granted to the king came to an end, and they met again at Stamford in Lincolnshire, on the 19th of April, 1215, being followed by nearly two thousand knights in arms. The king asked them what their claims were; they made at Stamford the same answer as they had made in London, and presented the charter which they had sworn to establish. "And why do they not demand my crown also?" exclaimed John in his fury; "by God's teeth, I will not grant them liberties which will make me a slave." This answer was taken as a declaration of war, and on the 5th of May following, the barons met at Wallingford, solemnly renounced their oath of allegiance, and at the same time named Robert Fitz-Walter general of the "army of God and of Holy Church."
