Then striking him again, by the help of Maulac he dragged him to the edge of the rock, and threw him headlong into the Seine, whose waters closed over the brave young Plantagenet, in his eighteenth year, ending all the hopes of the Bretons. The deed of darkness was guessed at, though it was long before its manner became known; and John himself marked out its consummation by causing himself to be publicly crowned over again, and by rewarding his partner in the crime with the hand of the heiress of Mulgrave. His mother, Queen Eleanor, is said to have died of grief at the horror he had perpetrated. She had retired, after the siege of Mirabeau, to the convent of Fontevraud, where she assumed the veil, and now shared the same fate as her husband, King Henry--like him, dying broken-hearted for the crimes of their son. She was buried beside him and her beloved Coeur de Lion. The Bretons mourned and raged at the loss of their young duke. His sister Eleanor was wasting her youth and loveliness in a prison, which she only left, after her oppressor’s death, to become a nun at Ambresbury; and they therefore proclaimed as their duchess her little half-sister, Alix de Thouars, who was, at four years old, presented to the States in her father’s arms, and shortly after married to an efficient protector, Pierre de Dreux, called, from his quarrels with the clergy, Mauclerc. Never had the enemy of the Plantagenets been so well served as by King John. Such was the indignation and grief of the whole French noblesse, that, when Pope Innocent III sent out a legate to mediate between the two kings, the barons bound themselves by a charter, “to second their lord, King Philippe, in his war against King John, notwithstanding the will of the Pope, exhorting him to contrive it without being dismayed by vain words, and agreeing to give him all assistance, and enter into no treaty with the Pope save with his consent.” Finding his nobles in this disposition, Philippe ventured on an unprecedented step, namely, that of summoning the King of England, as his vassal for Normandy and Anjou, to answer for the crime done on the person of his nephew, before his peers, namely, the other great crown vassals and barons holding fiefs directly from the King. John did not deny the competence of the court of peers, and sent Hubert de Burgh, and Eustace, Bishop of Ely, to declare that he would willingly appear, provided a safe-conduct was sent to him. Philippe declared that he certainly might come in safety; but when they asked if he guaranteed his security, supposing he was condemned, he replied, “By all the saints of France, no! That must be decided by the peers.” The bishop declared that a crowned head could not be tried for murder; the English barons would not permit it. “What is that to me?” said Philippe. “The Dukes of Normandy have certainly conquered England; but because a vassal augments his domain, is the suzerain to lose his rights?”
