Agree.

To place a woman on the battlefield, you could possibly have her into the fight (as cantinière helping the wounded or fighting disguised as soldier - not unusual by the time), then meeting the general in more civil circumstances.
A kind of fighting Pauline Fourès.

If you knows French, you could read the article in link, very informative on the status of women in the Army, and providing a sample of cantinières and women-soldiers, including a few praised by Napoleon (Mme Cazajus, Thérèse Figueur, Maria Schellinck).
