John then promised that he would appear before the court in Paris on the appointed day, and give up to Philip two small castles, Thillier and Boutavant, as security for his submitting to its decision.  April 28th passed, and both these promises remained unfulfilled.  One English writer asserts that thereupon “the assembled court of the King of France adjudged the King of England to be deprived of all his land which he and his forefathers had hitherto held of the King of France,” but there is reason to think that this statement is erroneous, and derived from a false report put forth by Philip Augustus for political purposes two or three years later.  It is certain that after the date of this alleged sentence negotiations still went on; “great and excellent mediators” endeavored to arrange a pacification; and Philip himself, according to his own account, had another interview with John, at which he used all his powers of persuasion to bring him to submission, but in vain.  Then the French King, by the advice of his barons, formally “defied” his rebellious vassal; in a sudden burst of wrath he ordered the Archbishop of Canterbury—­evidently one of the mediators just referred to—­out of his territories, and dashing after him with such forces as he had at hand, began hostilities by a raid upon Boutavant, which he captured and burned.  Even after this, if we may trust his own report, he sent four knights to John to make a final attempt at reconciliation; but John would not see them.

The war which followed was characteristic of both kings alike.  Philip’s attack took the form not of a regular invasion, but of a series of raids upon Eastern Normandy, whereby, in the course of the next three months, he made himself master of Thillier, Lions, Longchamp, La Ferteen-Braye, Orgueil, Gournay, Mortemer, Aumale, and the town and county of Eu.  John was throughout the same period flitting ceaselessly about within a short distance of all these places; but Philip never came up with him, and he never but once came up with Philip.  On July 7, 1202, the French King laid siege to Radepont, some ten miles to the southeast of Rouen.  John, who was at Bonport, let him alone for a week, and then suddenly appeared before the place, whereupon Philip immediately withdrew.  John, however, made no attempt at pursuit.  According to his wont, he let matters take their course till he saw a favorable opportunity for retaliation.  At the end of the month the opportunity came.

At the conclusion of the treaty in May, 1200, Arthur, after doing homage to his uncle for Brittany, had been by him restored to the guardianship of the French King.  The death of the boy’s mother in September, 1201, left him more than ever exposed to Philip’s influence; and it was no doubt as a measure of precaution, in view of the approaching strife between the kings, that John on March 27, 1202, summoned his “beloved nephew Arthur” to come and “do right” to him at Argentan at the octave of Easter.  The summons probably
