It appears that the King of England was at Windsor, celebrating the feast of St. George, and flattering himself that peace was established, when he received intelligence that the treaty of Malestroit had been rudely broken by the summary execution of his Breton allies. The king, whose temper was fiery, no sooner heard of this breach of faith and outrage on justice, than his blood boiled with indignation, and he vowed he would make Philip of Valois repent his handiwork.
At that time Sir Hervé de Léon, a knight of Brittany, who had stood sternly up for the interest of Charles of Blois against the English king and the Earl of Montfort, happened to be a prisoner in England; and Edward in the excess of his rage, bethought him of retaliation. Fortunately, however, Henry, Earl of Derby, the king's kinsman, had the courage to remonstrate, and to persuade Edward that such a course would be unworthy of his dignity and of the reputation he enjoyed throughout Christendom.
"My lord," said Derby, "if Philip of Valois has, in his rashness, had the villainy to put to death so many valiant knights, do not suffer your courage to be tainted by it; for, in truth, if you will but consider a little, your prisoner has nothing to do with this outrage. Have the goodness therefore to give him his liberty at a reasonable ransom."
Edward, after attentively listening to the earl, paused, reflected, indicated by gesture his concurrence in his kinsman's opinion, and ordered the captive knight to be brought to his presence.
"Ha! Sir Hervé—Sir Hervé," began the king, who by this time had recovered his serenity, "my adversary, Philip of Valois, has shown his treachery in too cruel a manner when he put to death so many knights. It has given me much displeasure, and it appears as if it were done in despite of us. If I were to take his conduct as my example, I ought to do the like to you, for you have done me more harm in Brittany than any other man."
"Sire——" said Sir Hervé, interrupting.
"Nay," continued Edward, "listen. I will preserve my honour unspotted, and allow you your liberty at a trifling ransom, out of my love for the Earl of Derby, who has requested it; but on this condition, that you perform what I am going to ask of you."
"Sire," said Sir Hervé, "I will do the best of my power to perform whatever you shall command."
"Ah, then, let us come to the point," continued the king. "I know, Sir Hervé, that you are one of the richest knights in Brittany, and if I were to press you, you would pay me forty thousand crowns for your ransom. But you will go to Philip of Valois, my adversary, and tell him, from me, that, by putting so many knights to death in so dishonourable a manner, he has sore displeased me, and I say and maintain that he has, by this act, broken the truce, and that, from this moment, I consider it broken, and by you send him my defiance."
"Sire," replied Sir Hervé, "I will perform your message to the best of my abilities."
