I've just watched an episode of the acclaimed Civil War documentary which often gets shown on Discovery or History Channel - playing this game has sparked an interest to know a lot more about it.
This episode dealt with late 1861 up to the end of Shiloh. It covered Gen McLelland's 'peninsular' campaign of early 1862. Apparently he sat outside Yorktown and did nothing, having been deceived as to CSA troop numbers by the cunning of Gen Magruder. Anyway, it said that McLellands force numbered above 100,000. Obviously there would have been further armies covering Washington, Mannasis, maybe further west as well.
Playing this game as the Union I am unable to raise anything like so strong an army by early 1862 especially if I also allocate resources and reinforcements to Tennissee as well. Does the game part from historical reality here or am I missing a trick or two??
