I know that duels (in the form popular in Europe of XIX and early XX century) didn't always end in death (dueling to death was even prohibited by some code e.g. Boziewicz code). I would like to know however if we have any statistics about how exactly dangerous duels were. How high were the odds of being killed when entering a duel. Also it would be good to know which type of duel (fencing or shooting) was more dangerous.
