Mac and Lee

From BoardGameGeek:

Mac and Lee is the second game in John Theissen's American Civil War Operational Series. Specific units and their strengths are hidden from your opponent as you perform a tense dance of cat-and-mouse maneuvers. This is especially important when modeling George McClellan's ill-fated Peninsula Campaign, where doubts about enemy numbers and positions exacerbated the extreme caution that saw the promise of “the young Napoleon” give way over the course of these operations to his reputation as a passive, bewildered commander who was hopelessly outmatched by his Confederate counterparts. If they want to succeed, the Union Player will need to be bolder and more decisive than Mac; the Confederate Player, for their part, must use a skillful mix of maneuver, bluff, and nerve to stymie the enemy's advance on Richmond. Knowing when to attack and when to hold back, when to run and when to make a stand, are paramount, and as ever, subject to the fortunes of war.
