Napoleonic 20: Waterloo 20

Waterloo 20 is a game based on the Waterloo campaign of 15-18 June 1815. One player commands the French army, taking the role of the returning Emperor Napoleon. The other player, known as the Allied Player, commands the Anti-French side. He assumes both the roles of Wellington for the Anglo-Dutch forces, and Blücher for the Prussian forces, respectively.

Two months after returning to France, Napoleon had an army of 280,000 men and was mobilizing half as many again for the next two months, but he was set upon by Allied coalition armies of nearly 1,000,000 soldiers who were preparing to move against France.

The British (110,000 men) and Prussians (120,000 men) were closest in Belgium, and Napoleon struck first before their numbers were combined against him. With speed and surprise, he invaded Belgium with fully 125,000 men in a bid to defeat each of these armies in turn before they could unite.
