I personally love questions like this. I’m always curious as to the process behind planning lines and making decisions about scrapping some in favor of others. If I had to ask a question like this, I’d be curious as to what the War of 1812 range was scrapped to make time for.
Interesting and quite strange war with an even stranger historiography that has traditionally varied widely between historians from the UK, Canada, and the different parts of the USA. Currently using JCA Stagg's 'The War of 1812: Conflict for a Continent' as my main go to at the moment, largely because from pages 171-186 he lists the hundreds of different sources available for just about anything related to the conflict.
I agree completely Babylon. The historiography is so interesting. What originally drew me to the war though is simply the participation of the United States. The Napoleonic wars have always been one of my favorites to study, but I’ve always wondered what an American Napoleonic army would look like, yet because of the war of 1812 we know. There’s something about Americans in shakos that I just love. On top of that the actual battles and skirmishes of the war are pretty interesting as well.
