Sir Isaac Brock and the War of 1812
Do be sure to check out pictures and re-enactments of the War of 1812 and the American Revolutionary War from the Canadian/British perspective. You will get a much broader, and better view of British focused forces and society that way.
I thought it worth pointing out to you the links to Canadian photos and theme parks of the period. My suspicion was that you might find the American sources readily. The Canadian/British ones? Perhaps not so much...
Searches for "beaver hats" are similarly helpful for finding period images of tricorns and tophats. The beaver fur trade in Canada was all aimed at obtaining felt for use in making hats -- not beaver tails, as they are often commonly misunderstood to mean
I honestly don't think it is possible to understand this period without getting a thorough understanding of the Royal Navy. There is no better (or enjoyable) source for that than Patrick O'Brians'
Aubrey and Maturin series. A few novels from the series were mashed together in the film
Master & Commander/ The Far Side of the World.
The novels are outstanding but are diffuclt to read because the author writes in a style authentic to the period and uses naval terminology throughout without apology.
I would
heartily recommend the audio versions of O' Brian's novels. The language and terminology is so authentic that I have never listened to a more transportive audio book than those written by Patrick O'Brien. It is the closest you are likely to come to time travel. Beware of the second novel in the series (it's a deliberate pastiche of Bronte). But otherwise - the series is outstanding, truly outstanding. You WILL understand British military society and, more importantly, the British Navy during the Napoleonic Wars and the War of 1812 after reading/listening to those books.
