Smoke By the River

What if The Native Americans won the war for control of the continent and modernized in their own way parallel to Europe? An arrowhead hunter named Kevin Whitecoate suffers a head injury while hunting and finds himself in the past. He inadvertently changes the course of history by sharing his modern education with the natives in the 1600s. He uses his knowledge of history to prevent Indian massacres and helps drive the British invaders back to England.
