I think Sgt. York was accurate in general but a lot of the details were wrong. For instance in the movie he had a brother and sister but in actuality came from a very large family.
Minor errors I can think of off hand are they had him use a Luger instead of the correct 1911 and a Springfield while he actually used a 1917 Enfield.
I bet there are a lot of other odds and ends that are wrong but in general it is right.
thanks.....yup...came across all that in reading about him. I reckon the movie changed in bits which the director knew would translate better on the screen. Glad to know others are aware of Sgt York’s contributions. :)
