Whether Arthur had been killed by King John and flung into the Seine, or whether he had fallen into the river and been drowned while attempting to escape from the castle of Rouen, remains an historic mystery. But neither the Bretons nor Philip Augustus expressed any doubt on the subject. Within a week after the tragical event the Bretons demanded justice on the head of the murderer; and Philip summoned John, as one of his vassals, to appear before the Twelve Peers of France, and answer to the charge. Without denying the jurisdiction of the court, John declined to appear unless granted a safe conduct; and, the Twelve Peers having pronounced sentence of death and confiscation, Philip took up arms to execute the sentence, and seized cities and castles in such numbers, that, ere long, John retained little or nothing of the Continental empire of the Plantagenets, save Bordeaux, and a nominal authority in Guienne. One effort he did make to redeem his fortunes. But, losing heart and hope, he abandoned the struggle, and, returning to England, entered on that contest with the Church which was destined to involve him in ruin. In the year 1205, Hubert, Archbishop of Canterbury, departed this life, and in his place the monks of Canterbury elected Reginald, their prior, to the vacant see. The king, however, far from sanctioning their choice, insisted on elevating John Grey, Bishop of Norfolk, to the primacy; and the dispute between the monks and the crown was referred to Innocent III., one of those popes who, like Hildebrand and Boniface VIII., deemed it their mission “to pull down the pride of kings.” In order at once to show his impartiality and his power, Innocent set aside the man nominated by the monks and the man nominated by the king, and gave the archbishopric to Stephen Langton, a cardinal of English birth, who was then at Rome. The monks, in consequence, found themselves in an awkward predicament. However, they were under the necessity of doing as the Pope ordered. In vain they talked of their scruples and fears, and protested that they could do nothing without the royal sanction. When urged, only one monk stood firm; all the others, out of deference to the head of the Church, confirmed the nomination of Stephen Langton.
