My grandmother was in that war, as near to the front lines as an Army field hospital could get in the days before M.A.S.H. Units.

It does look like it would be a great film to watch.
My grandfather was an ambulance driver in Argonne, France, during WW-I.....I never knew that until long after he had died......
