The rules are the product of 10 years of labour on my part. I was never satisfied with generic rules that covered the "Horse & Musket" period, some stretching from the Wars of Marlborough to the Franco-Prussian War. What was needed was something that gave the feeling of desperation the small armies of the wild North American continent must have felt; from the conscripted militiaman to the long service professional, and to
the Indian warrior fighting to avoid extermination.
In battles where a battalion represented up to a quarter of the forces fielded, rules were required to make the commander feel "intimate" with the scanty units under his command. Each regiment needed to feel like a separate entity, with personality, so that they would be understood and used as they would have been at the time.
Further, commanders themselves had such a huge impact on their small armies, that players needed to understand their strengths and weaknesses, and the frustration of the subordinates often had to suffer under their command.
