I'm an avid player of a video game in which the player takes a role of a single soldier from the napoleonic wars era. It's a lot of fun, and we have hundreds of players in regiments fighting daily battles using chain of command and different detachments. Because of the morale not being an issue and easy communication the game is far from realistic but there are a lot of tactics that are as useful as they were 200 years ago o the real battlefields. I'm really interested in learning whatever the real officers learned in order to satisfy my curiosity and hopefully make myself a better commander. I'm searching for training materials (books, maybe illustrations) used in that era. If anyone could link me something like that I'd be grateful.
