I don't know anyone who hasn't heard of Joan of Arc.

It is always important to notice that Joan of Arc didn't fight and never killed anyone. She said it herself during her trial. She did have a sword and drew it some times but never used it.

Most of her job was carrying a big flag (a type of war flag called standard) which was very dangerous and important in medieval warfare, but didn't require any actual fighting. She also acted as a symbol for inspiring the troops and maybe participated in the planning of some battles (something impressive for a illiterate teenage peasant), but it is certain that she would never survive actual combat.
