The "1812 Grand Tactical game" is a simulation of the French invasion of Russia. The defeat of Napoleon in this campaign eventually led to the collapse of the French Empire, and the demise of that truly great military leader. The Grand Tactical game simulates the mechanics of strategic maneuver and tactical decision in this campaign. The game is divided into three Scenarios: Scenario 1 starts in June with the opposing forces deployed and ready to start the campaign. Scenario 2 starts in August, with Napoleon deep inside Russia and preparing his final drive to Moscow. In October, Napoleon in Moscow is about to begin the epic winter retreat as Russian armies converge from all directions.
