Next he turned west and marched through Germany, but was defeated at the Battle of Mingolsheim on 27 April 1622. He then joined with the Spanish general Duke Gonzalo Fernández de Córdoba – not to be confused with the famous Spanish general of the same name from the Italian Wars in Italy at the end of the 15th century – and was victorious at the Battle of Wimpfen against George Fredrick, Margrave of Baden-Durlach on 6 May; this victory occurred after the enemies’ ammunition tumbril was hit by cannon fire and exploded.
