Well most of this movie is soft porn. In fact the name of the film should be Levottomat 7 or something similar, this is the same stuff again but now in some historically motivated context. Unfortunately the actors in main roles had read their history lessons much better than the script writer or anyone in the production team.
The movie represents a white side soldier who, despite being clearly a Nazi, suddenly starts to feel pity when the evil whites shoot at unarmed and barely dressed ladies. He decides to save the one good looking one. It is a factual mistake that the man is given a rank of Private, despite being a Jaeger trained in Germany. Absolutely none of the Jaegers in the Civil War served as mere Privates, even the ones with bad physical condition were promoted to at least to the rank of Corporal.
Another thing that I quite wondered was the Judge's Russian wife, who wasn't familiar with German language at all even if she could play Beethoven numbers by request. The academical Russians of the early 20th century knew German rather well. The same wife character could be a bark at the modern custom of having a Russian wife, whom the writer presents as a rather lustful Lady.
Nothing new really in this one, except that it's the least story conveying good vs bad juxtaposition for a while.
