 FitzWalter was too powerful, and too aggressive in defence of his rights, for the local populace to confront him in court, and it was not until 1351 that he was finally brought to justice.The King despatched a royal commission to Chelmsford to investigate a broad range of social ills, among which was FitzWalter and his gang.Although most of his force received little or no punishment, FitzWalter himself was arrested and sent to London; he was immediately imprisoned in the Marshalsea.
