How about this for a thought? St Joan of Arc, to my knowledge, never fought in the actual battles. She led the charges, and was at the forefront, yes, but I don't think she carried a sword for killing. At least as far as I know she never killed anyone. And then, too, she was maidenly and modest. She was feminine (not FeminIST), and by her very femininity inspired and led her soldiers to act as true Catholic men. I don't think that there was ever any rough language or swearing in her camps--certainly not in her presence! And all the soldiers attended Mass and Confession following her example.
Perhaps there is someone more knowledgeable about her life than me that could elaborate on it more.
