During the Palatinate campaign of the Thirty Years' War, Spanish forces under Spinola sought to seize key Protestant-held towns in the Electorate of the Palatinate. Oppenheim was a strategically important position, and the Protestant army of Joachim Ernst, Margrave of Brandenburg-Ansbach, was tasked with its defense against Spanish advances.
On 14 September 1620, Spinola's Spanish army executed a feigned maneuver toward Worms to deceive the Protestant defenders. With the Protestant forces misled and off balance, the Spanish troops captured Oppenheim with little difficulty, overcoming the army commanded by Joachim Ernst without significant resistance.
The fall of Oppenheim inflicted a severe blow on Protestant forces in the Palatinate, undermining their defensive position in the region. The Spanish success reinforced their dominance during the Palatinate campaign and contributed to the broader erosion of Protestant power in the Electorate during this phase of the Thirty Years' War.
