by Archbishop Walter of Rouen, who had come from Messina charged with a special commission from Richard to deal with the crisis in England.[144] John, on receiving the chancellor’s message, burst into one of the paroxysms of fury characteristic of his race. “He was more than angry,” says a contemporary; “his whole body was so contorted with rage as to be scarcely recognizable; a scowl of wrath furrowed his brow; his eyes flashed fire, his colour changed to a livid white, and I know what would have become of the chancellor if in that hour of fury he had come within reach of John’s hands!” In the end, however, the archbishop persuaded both John and William to hold another conference at Winchester on July 28.[145] John secured the services of four thousand armed Welshmen, whom he apparently brought up secretly, in small parties, from the border, and hid in various places round about the city. No disturbance, however, took place; some of the bishops, under the direction of Walter of Rouen, drew up a scheme of agreement which, for the moment, both John and William found it advisable to accept. The castles of Nottingham and Tickhill were surrendered by John to the king {1191 July 28} in the person of his special representative the archbishop of Rouen, who was to give them in charge, one to William of Venneval--a liegeman of the king, but a friend and follower of John--the other to William the Marshal; these two custodians were to hold them for the king till his return, and then “act according to his will concerning them”; but if he should die, or if meanwhile the chancellor should break the peace with John, they were to restore them to John. New custodians were appointed, on the like terms, to six royal castles which stood within John’s territories,[146] and also to two castles which Richard had expressly granted to him,--Bolsover and the Peak. Any new castles built since the king’s departure were to be razed, and no more were to be built till his return, save, if necessary, on the royal demesnes, or elsewhere in pursuance of special orders, written or verbal, from himself. No man was to be disseised either by the king’s ministers or by the count of Mortain, save in execution of a legal sentence delivered after trial before the king’s court; and each party was pledged to amend, on complaint from the other, its own infringements of this rule, which was at once applied to the case of Gerard de Camville. Gerard, having been disseised without trial, was reinstated in his sheriffdom; but his reinstatement was ordered to be immediately followed by a trial before the Curia Regis on the charges brought against him, and the decision of the Curia was to be final; if it went against him, John was not to support him in resistance to it; and John was further bound not to harbour any known outlaws or enemies of the king, nor any person accused of treason, except on condition of such person pledging himself to stand his trial in the king’s court.
