But did she KILL anyone?
Being wounded is one thing. Being on a horse certainly has her at an advantage, but she had a number of moralistic attitudes that may have made it difficult, or even impossible, to personally kill someone. We have no accounts of her lopping off someone's head or cutting off a hand or an arm!
There are a lot of women who are good at shooting guns, though. Don't know how they fare in combat, though. I know there are some top notch snipers, though.
