A neat and elegant set of wargame rules for Napoleonic era land battles fought at a high level, regiment or above, and yet accommodating the influence of individual leaders.
It's a turn-based system, quite logical in approach, written with an eye to quick resolution of each turn so that you can see the effect of your tactical choices developing on the table before you. Once mastered, frantic checking of rules becomes unnecessary as the sequence of actions fits the rythym inherent at this level of abstraction.
It is predicated around the use of miniatures, although those who do not care for them could devise a system of counters without too much difficulty.
Rules are presented clearly and well-illustrated, and they take acount of historical knowledge concerning tactics and characteristics of the different nationalities involved.
The whole thing is nicely-presented and if you enjoy the broad picture, the wide sweep of events on the battlefield, and are happy with a nice balance of abstraction over realism, these rules are worth a look.
