The actual battle of Tippecanoe lasted around two hours, not minutes. The battle started before dawn and ended after the Indians retreated after running low on ammunition. The town of Tippecanoe was not burnt down, the native town was destroyed. The movie only shows Militia in gray uniforms, but there were also Regulars (in blue) and Dragoons (mounted infantry) who played a major role in the battle. Finally, although hand to hand combat was shown, none of the Militiamen had a bayonet on his musket.
