The Brits Have a Right to be Upset
I looked up and down the postings for this movie and I haven't found an important point stated. It's in regard to the scene where the British soldiers rounded up the inhabitants of the village, put them in the church, and burned them to death.
THIS IS SOMETHING THE NAZIS DID TO A VILLAGE IN FRANCE IN 1944!! Unless an incident like this actually happened during the Revolutionary War (which I highly doubt), the Brits have a right to be outraged by this movie.
