The demand for the restoration of the royal castles produced the first outbreak. Just as, at the beginning of the reign of Henry II., William of Aumâle had refused to surrender Scarborough, so now his grandson refused to surrender Rockingham. Immediately after the coronation the king was brought to the siege, but the garrison fled as he approached. The earl, undismayed, seized in 1221 the castles of Biham and Fotheringay; and although he resisted not only the strength of the government but the sentence of excommunication also, he was forced to submit. In 1222 and 1223 the struggle was renewed in more formidable dimensions. The Earl of Chester, who had at first supported the government, made himself the spokesman of the feudal party; and the foreigners, the chief of whom was Falkes de Breauté, did their best to unseat the justiciar, who was now recognised as the chief man in the administrative council. The evil was increased by the discord in the council itself. Peter des Roches was known to prompt the resistance to Hubert de Burgh and to be the patron of the foreigners; he neither understood nor loved the institutions of England, and although an able and experienced man was very ambitious and altogether unscrupulous. In 1224, however, the contest was decided. An act of violent insubordination on the part of Falkes de Breauté brought down the king and the kingdom upon him; the great conspiracy of which he held the strings was broken up, and he himself, notwithstanding the secret support of Peter des Roches and the open mediation of the Pope, was banished from the land. His fall involved the humiliation of the feudal lords who were allied with him, and the expulsion of the foreigners whom he represented and headed. Peter des Roches himself had to take a subordinate place. [Sidenote: Work of Hubert de Burgh. ] [Sidenote: Re-issue of the Charter. ]
