This is all very educational. For example, I found this:

 

 

 

For some time before the mid-18th century, swordsmen dueling at dawn often carried lanterns to see each other. This happened so regularly that fencing manuals integrated lanterns into their lessons. An example of this is using the lantern to parry blows and blind the opponent.^[54] The manuals sometimes show the combatants carrying the lantern in the left hand wrapped behind the back, which is still one of the traditional positions for the off hand in modern fencing.

 

And this!

 

 

 

On rare occasions, duels with pistols or swords were fought between women; these were sometimes known as petticoat duels

 

I suppose all those layers and whalebone would stop a bullet.
