The poorly worded Bärwalde treaty gave Gustavus a great deal of freedom, while Magdeburg brought him support from the Dutch and England among others. This made him increasingly independent of French control; his upward trajectory ended only with his death at Lützen in November 1632. Swedish intervention continued with French support, until defeat at Nördlingen in September 1634; this forced the Swedish army to temporarily retreat, while most of their German allies made peace with Emperor Ferdinand in the 1635 Treaty of Prague.
