The effect of this announcement proved at once the wisdom of Hubert and the folly of those to whose counsel John had yielded. The fury of the Bretons became boundless; they vowed never to leave a moment's peace to the tyrant who had committed such a ghastly crime upon their Duke, his own nephew, and Hubert soon found it necessary, for John's own sake, to confess his fraud and demonstrate to friends and foes alike that Arthur was still alive and uninjured. John himself now attempted to deal with Arthur in another way. Being at Falaise at the end of January, 1203, he caused his nephew to be brought before him, and "addressed him with fair words, promising him great honors if he would forsake the King of France and cleave faithfully to his uncle and rightful lord." Arthur, however, rejected these overtures with scorn, vowing that there should be no peace unless the whole Angevin dominions, including England, were surrendered to him as Richard's lawful heir. John retorted by transferring his prisoner from Falaise to Rouen and confining him, more strictly than ever, in the citadel. Thenceforth Arthur disappears from history. What was his end no one knows. The chronicle of the Abbey of Margan in South Wales, a chronicle of which the only known manuscript ends with the year 1232, and of which the portion dealing with the early years of John's reign was not compiled in its present form till after 1221 at earliest, asserts that on Maunday Thursday (April 3, 1203), John, "after dinner, being drunk and possessed by the devil," slew his nephew with his own hand and tied a great stone to the body, which he flung into the Seine; that a fisherman's net brought it up again, and that, being recognized, it was buried secretly, "for fear of the tyrant," in the Church of Notre Dame des Prés, near Rouen. William the Breton, in his poem on Philip Augustus, completed about 1216, relates in detail, but without date, how John took Arthur out alone with him by night in a boat on the Seine, plunged a sword into his body, rowed along for three miles with the corpse, and then threw it overboard. Neither of these writers gives any authority for his story. The earliest authority of precisely ascertained date to which we can trace the assertion that Arthur was murdered was a document put forth by a personage whose word, on any subject whatever, is as worthless as the word of John himself--King Philip Augustus of France. In 1216--about the time when his Breton historiographer's poem was completed--Philip affected to regard it as a notorious fact that John had, either in person or by another's hand, murdered his nephew. But Philip at the same time went on to assert that John had been summoned to trial before the supreme court of France, and by it condemned to forfeiture of all his dominions, on that same charge of murder; and this latter assertion is almost certainly false. Seven months after the date assigned by the Margan annalist to Arthur's death--in October,
