Battlevision: The Battle of Shiloh
Rich Hamilton recently reviewed Battlevision: The Battle of Shiloh over at the Armchair General. It is a PC product (this is NOT a game, for those wondering) that covers the Battle of Shiloh in great detail. The most exciting thing is that the product contains detailed Orders of Battle down to regimental and battery level, includes officers in command of given regiments, and details casualties. If you are looking to design wargame scenarios covering Shiloh, this looks like a pretty solid product.
