If you are a history buff and interested in the Napoleonic wars, don't bother watching.
The film follows the usual trope of playing fast and lose with historical fact. It's such a shame because it wouldn't have been difficult to make a historically accurate film that was just as good and entertaining. I won't list the blatant inaccuracies but they are akin to Churchill leading the charge up the beaches on D-day!
A film spoiled I'm afraid.
