That story could only happen in real life.
For those unfamiliar, York was a young man seriously dedicated to peace. IIRC, he was drafted.
Anyway, he found himself alone and facing a German installation that was about to do some things that were not peacable. (Was it executing the rest of his unit? I really should look this up again.) So Sgt. York captured them. All by himself. The story goes that he later explained that he surrounded them...
Saved many Allied lives. And did so while respecting, as much as possible under the circumstances, the lives of the enemy. From what I have heard, he remained a very gentle and peacefull man.
A hero in every sense of the term*.
It is a shame that his story is not more commonly known.

* Including the nearly ancient Greek one. But not the really ancient Greek term. That term meant a vampire-type undead person, and later the usage changed to refer specificaly to one who lives past death by epic poetry of his deeds.
