The Swedes won. They smashed the Imperialist left wing but Imperialist reinforcements arrived in the nick of time. Unfortunately it was the Imperialist player's first game and so what he did was send a little to each sector. This meant he had some success on his right and probably would have won there. But the Swedes were able to turn some of their victorious cavalry on the Imperialist left into their centre, game over.
It was a good game but the scenario will need a few tweaks. For me the highlight was Gustav II Adolf being the 'Chicken of the North'. The Swedish player knew he died at this battle so he hid the king's figure out of harms way for the entire battle
