In the spring of 1622 General Tilly moved the League's army to invade the Electoral Palatinate. They were defeated by General Mansfeld's troops at the Battle of Mingolsheim on 27 April 1622. Retreating eastwards they were joined by a Spanish army under General Córdoba. When another Protestant army under Georg Friedrich, Margrave of Baden attacked on May 6, Tilly's League force convincingly won the Battle of Wimpfen, scattering the enemy. The Battle of Höchst on June 20 proved to be the decisive victory for 1622.
