Richard the Lionheart told Philip, the martial Bishop of Dreux, to decide whether he was a bishop or a knight.
During the Third Crusade, Philip of Dreux, Bishop of Beauvais, spread the rumour that Richard the Lionheart had procured the assassination of Conrad of Montferrat; and after Richard was taken prisoner in Austria in 1192 he tried to make his detention as long and unpleasant as he could. In 1197, three years after his release, Richard stumbled across an opportunity for payback.
When Richard I heard that the town of Verneuil in Normandy was under threat, he made a vow that few could be expected to take so literally.
On March 20th, 1194, Richard I returned to England after two years of captivity to Leopold of Austria, with whom he had quarrelled on the Crusades. Richard’s brother John, who had tried to keep him locked up as long as possible, fled to the protection of Philip II of France; but barely a month had passed before Richard quitted his capital yet again, and was on his way back to Normandy.
