 Wallenstein defeated Mansfeld in the Battle of Dessau Bridge in 1626.The remnants of Mansfeld's army left Central Germany, and turned to Silesia and Hungary to regroup with Gabriel Bethlen's forces.After Tilly had defeated Christian IV in the Battle of Lutter am Barenberge in August 1626, and Bethlen was neutralized in the (third) Peace of Pressburg in December, Tilly and Wallenstein were able to subsequently expel Christian IV from the North German plain, organized in the Lower Saxon and Upper Saxon imperial circles, and pressure him even in Danish Jutland.
