From Worthington:
Lincoln is a fast-paced, light, two-player, card-driven strategy wargame set in the American Civil War that allows you to re-fight the entire American Civil War at a strategic level in under two hours.
Game play uses point-to-point movement and area control, hidden army strengths, and decks of cards providing the command choices and luck; there are no dice. The Union and Confederate players each have their own card decks, reflecting the relative strengths and weaknesses of both sides. The Union player must do all the running to win the game by the time they have cycled through the Union card deck for the third time, having accumulated 
Each time the decks are cycled, the Union player adds some better quality cards, becoming stronger as the game progresses, where as the Confederate player adds lower quality cards, becoming weaker. The underlying game mechanism is one of “deck destruction” rather than the more normal deck-building.
Cards have multiple uses and can be recycled if used one way but during the course of the game you have to decide which cards are going to be permanently sacrificed from your deck cycle to allow you to build units.
