First Blood in the Crimea: Battle of the Alma

From BoardGameGeek:

Two player grand-tactical game using the alternating-actions system introduced in Wagram. That system places the emphasis on players' mastery of overall operations rather than on the minutiae of tactics. In effect, players role-play each side's supreme commander, making the decisions those two men would make rather than the whole command chain, as is often the case many complex tactical-level games.
