Battle of Breitenfeld
At the Battle of Breitenfeld, in 1631, Adolphus proved the effectiveness of the changes made to his army, by defeating Johann Tserclaes, Count of Tilly. Although severely outnumbered, the Swedes were able to fire between three and five times as many volleys of artillery, and their infantry's linear formations helped ensure they didn't lose any ground. Battered by cannon fire, and low on morale, Tilly's men broke ranks and fled.
