England. On 19 July his estates were restored. John also granted a hundred marks to his steward as compensation, and directed a general inquest into his losses like those made in the case of the clerks who had suffered by the interdict. Magna Carta revolt Fitzwalter, however, remained a vigorous opponent of John's later measures. Matthew Paris said that John specially hated him, Archbishop Stephen Langton, and Saer de Quincy. In August 1213, he was at St Paul's Cathedral in London when Archbishop Langton read a charter signed by Henry I and announced that services could be conducted ahead of the lifting of the interdict on England.

In 1215 Fitzwalter was the first mentioned in the list of barons who assembled on Easter week (19–26 April) at Stamford. He accompanied the revolted lords on the march to Brackley in Northamptonshire on 27 April. But John now formally refused to accept the long list of demands which they forwarded to him at Oxford. Thereupon the barons elected Fitzwalter their general, with the title of "Marshal of the Army of God and Holy Church".

On 17 May Fitzwalter entered the city at the head of the "army of God", though the partisans of John still held out in the Tower. Fitzwalter and the Earl of Essex specially
