But I can’t find anything definitive. I watched a private screening of the movie and was told everything was true, based on what they were able to find in journals, etc.

With 17 Miracles, I know T.C. Christensen used stories that the Church hasn’t felt comfortable with, or hasn’t been able to verify. I don’t know what goes in that process from a historians point of view. But I wouldn’t be surprised if in Escape From Germany, he similarly took some liberties based on a vague journal entry or an oral history or unverifiable source.

Who knows.
