Here is more food for thought:
I don't rightly remember what war it was... (WW2?) but Poland was being invaded by Russia and all their manpower was spent and destroyed on the battlefield. The atheistic Russian onslaught threatened to over-run Catholic Poland. In order to save their country from the pagans, young girls and older women picked up arms and defended their land, driving the Russians back, though with much blood shed.
Surely, St. Joan of Arc would have been an inspiration for some of these women (who were drafted?) to fight with all they had. If these women and girls had not sacrificed themselves, what horrid fate would have befallen their land?
Also, what a humiliation for Russia to be beaten by women! Some men, huh? But that is what happens when a woman HAS to fight and has God on her side!
I think that in the case of both Joan of Arc and the women of Poland, it was a matter of preserving Faith, culture, and the safety of the Motherland.
