The Battle of Rocroi was fought on 19 May 1643 - mere days after the passing of Louis XIII of France that left his five-year old son Louis XIV of France on the throne - late in the Thirty Years' War. It resulted in a victory of the French army under the Duc d'Enghien, against the Spanish army under General Francisco de Melo. Further, it is considered the turning point of the perceived invincibility of the Spanish tercio.
