Campaign Eylau-Friedland recreates the battles of the campaign in Poland of 1806-07. These were fought initially in the frozen countryside of Poland and East Prussia during the winter months of December through February and in the spring of 1807 at the end of which the French and their allies emerged victorious. Now you can take control of either the French or Allied armies and refight the famous battles which decided the fate of the Fourth Coalition and brought about the birth of the Grand Duchy of Warsaw and saw the Allies foiled once again by Napoleon.
