1354, his favorite, Charles of Spain, arrived at Laigle in Normandy.  The King of Navarre, having notice thereof, instructed one of his agents, the Bastard de Mareuil, to go with a troop of men-at-arms and surprise him in that town; and he himself remained outside the walls, awaiting the result of his design.  At break of day, he saw galloping up the Bastard de Mareuil, who shouted to him from afar, “’Tis done.”  “What is done?” asked Charles.  “He is dead,” answered Mareuil.  King John’s favorite had been surprised and massacred in his bed.  John burst out into threats; he swore he would have vengeance, and made preparations for war against his son-in-law.  But the King of England promised his support to the King of Navarre.  Charles the Bad was a bold and able intriguer; he levied troops and won over allies amongst the lords; dread of seeing the recommencement of a war with England gained ground; and amongst the people, and even in the king’s council, there was a cry of “Peace with the King of Navarre!” John took fright and pretended to give up his ideas of vengeance; he received his son-in-law, who thanked him on bended knee.  But the king gave him never a word.  The King of Navarre, uneasy but bold as ever, continued his intrigues for obtaining partisans and for exciting troubles and enmities against the king.  “I will have no master in France but myself,” said John to his confidant:  “I shall have no joy so long as he is living.”  His eldest son, the young Duke of Normandy, who was at a later period Charles V., had contracted friendly relations with the King of Navarre.  On the 16th of April, 1356, the two princes were together at a banquet in the castle of Rouen, as well as the Count d’Harcourt and some other lords.  All on a sudden King John, who had entered the castle by a postern with a troop of men-at-arms, strode abruptly into the hall, preceded by the Marshal Arnoul d’Audenham, who held a naked sword in his hand, and said, “Let none stir, whatever he may see, unless he wish to fall by this sword.”  The king went up to the table; and all rose as if to do him reverence.  John seized the King of Navarre roughly by the arm, and drew him towards him, saying, “Get up, traitor; thou art not worthy to sit at my son’s table; by my father’s soul I cannot think of meat or drink so long as thou art living.”  A servant of the King of Navarre, to defend his master, drew his cutlass, and pointed it at the breast of the King of France, who thrust him back, saying to his sergeants, “Take me this fellow and his master too.”  The King of Navarre dissolved in humble protestations and repentant speeches over the assassination of the Constable Charles of Spain.  “Go, traitor, go,” answered John:  “you will need to learn good rede or some infamous trick to escape from me.”  The young Duke of Normandy had thrown himself at the feet of the king his father, crying, “Ah! my lord, for God’s sake have mercy; you do me dishonor; for what will be said of
