Is there any historical accuracy in The Patriot movie?
As the name of the film shows, this production is largely a fictitious story told in order to pain the American revolutionaries as heroes and the British as war criminals. As far as accuracy goes, the uniforms and costume designs are as close as is possible and many of the events, such as children being used as soldiers, did occur.
However, the large majority of the events and details within the film are fictitious. Within the story, slaves were paid and subsequently freed by the revolutionaries after the war, which did not occur.
British troops also did not commit mass slaughters of American civilians or prisoners of war, although it was common for soldiers to be held in such poor conditions that they died of neglect or disease.
The role of the French is also vastly underplayed, and the battle tactics shown are almost entirely invented. In all, the film is accurate in that the American Revolutionary War did take place, but the details of the film are almost entirely fictitious.
