Factual error: The movie "Santa Fe Trail" (1940) starring Errol Flynn, Ronald Reagan and Raymond Massey, is the story of John Brown's raid on Harper's Ferry in 1859. The president is shown to be Abraham Lincoln, who wasn't inaugurated until February of 1861.
Factual error: George Armstrong Custer was not involved with the US Army's attack on John Brown at Harper's Ferry in 1859. He was a a first year man at West Point and was not in the regular army until 1861.
