Our ESR Campaign Guides are intentionally designed so that you can use them with whatever your favorite Napoleonic wargaming system is, we do this by offering:
• Maps in scale miles not inches
• Reinforcement arrivals in time not turns
• Orders of battle down to battalions
• And hundreds of uniform plates
The Commander and Unit ratings we include are based on Et sans résultat! Second Edition, but we even maintain a website to help you convert ESR's ratings to other popular systems.
