• French-Spanish Rivalry: France and Spain were two of the major Catholic powers in Europe, yet they were rivals. The battle was part of the broader Franco-Spanish War (1635–1659), which was itself a theater of the larger Thirty Years’ War.

The Battle

• Tactics and Outcome:

  • The battle began with a strong Spanish attack, but Condé’s strategic acumen turned the tide. He effectively utilized his cavalry to outflank the Spanish forces.
  • The French managed to break the Spanish lines, leading to a rout. The Spanish infantry, particularly the tercios, fought valiantly but were eventually overwhelmed.
