This is essentially two books. The first, of about 87 pages, is a very well-written account of military events surrounding the surrender at Detroit. The author was present as a volunteer in the Cincinnati Light infantry, and claims that as acting assistant quartermaster he was in close contact with the officers and heard their discussions and reactions throughout. It was written as a first-person narrative, but his intervening research on the topic enabled him to fill in details he did not witness.
The second half of the volume is the biographical sketch of Tecumseh. The author claims to have had considerable familiarity with Indians in the region, and treats Tecumseh and the Shawnees with great respect.
