King Gustavus ll headed the Swedish/Saxon army which outnumbered the Catholic League army under Count Tilly. However the Saxon contingent were raw inexperienced troops. Tilly chose the ground and arranged his force in a traditional way. Gustavus was an innovative commander who brought a new arrangement to the battlefield. The battle looked lost to the Swedes when Tilly's men broke the Saxons who fled the field. But the flexibility and all-arms set up enabled the Swedes to counter attack successfully, now against superior numbers, and to win a decisive victory.
