How did Albrecht von Wallenstein force Gustavus Adolphus out of Bavaria and Franconia?

Albrecht von Wallenstein forced Gustavus Adolphus out of Bavaria and Franconia between July and September 1632 by employing a defensive strategy.1

Specifically, Wallenstein utilized a threat against the city of Nuremberg to compel the Swedish king to abandon his campaign in Bavaria and move to relieve the city. This maneuver led to a tense war of movement, during which Gustavus Adolphus unsuccessfully attacked Wallenstein’s fortified positions at the Alte Veste. By maintaining this defensive posture, Wallenstein effectively neutralized the Swedish threat in those regions before the two forces eventually clashed at the Battle of Lützen.21
