Told through the eyes of Langdon Towne, this story centers around the exploits and character of Robert Rogers, the leader of Rogers’ Rangers, a colonial force fighting with the British during the French and Indian War. The book is divided into two distinct parts; the first part is a meticulous recreation of the raid by Rogers’ Rangers on the Indian village at Saint-François-du-Lac, Quebec (Saint Francis) and a settlement of the Abenakis, an American Indian tribe. The second part covers Rogers’ later life in London, England and Fort Michilimackinac, Michigan.  The first part of the book was made into a highly rated film in 1940, starring Spencer Tracy and Robert Young, only three years after the book was published.  https://en.wikipedia.org/wiki/Northwest_Passage_(film)
