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 me, having prayed King Charles and his barons to dine with me, if you do treat me thus?
It will be said that I betrayed them." "Hold your peace, Charles," answered his father: "you know not all I know." He gave orders for the instant removal of the King of Navarre, and afterwards of the Count d'Harcourt and three others of those present under arrest.
