An arrow shot into the sun

Late 18th century, England and France are fighting for the possession of the American continent. Native American tribes such as Hurons and Mohicans have joined the war and if people aren't bombing themselves to death, the more primitive ways like scalping and burning humans alive are as effective causing chaos and increasing the bodycount. It's a Michael Mann film from 1992, often cited as a masterpiece and a timeless classic. Were I to say it's decent but overrated and not aged particularly well, I'd prob'ly be wrong.
