How did women help out with World War I? What did women contribute during the war?

Good question,
because it is important to keep in mind that all wars are collaborative efforts. So, first of
all women did all the things that men did, who went off to war. For example, they worked in the
fields in the farms and took care of daily life (whatever had to be done). They also helped more
directly by driving ambulances, serving as medical persons, and working in other non-combatant
positions. They also helped by knitting things for the men, and doing whatever was needed for
the war campaign.
