I find that the US Civil War is quite possibly the most interesting period of history outside of the Classical Era. It is absolutely intricate in all areas, personal, political and military. Each soldier in that war knew someone on the other side and had their own beliefs on who or what they were fighting for and against. It showed some of the most amazing examples of generalship and military genius in the history of warfare. And it is made all the more amazing by the simple fact that such a wide ranging and brutal conflict, was fought over only several states and held the fate of the most significant nation of modern times in the balance.
Its truly fantastic when history, however small, is brought to life
