Afraid not, also I learned today that the last emperor of constantinople, after the city fell, became suitably enraged and charged the invading turks with a group of 50 men, without his cloak or crown and died like an ordinary soldier. Also that John the blind of Bavaria actually charged the english at the battle of crecy whilst tied to two other knights, so that he could still fight, he managed to kill 4 enemy knights before he was finally brought down.
Say what you want for medieval people, they knew how to go out in style.
