Battle of Maya: The Battle of Maya (25 July 1813) saw an Imperial French corps led by Jean-Baptiste Drouet, Comte d'Erlon attack the British 2nd Division under William Stewart at the Maya Pass in the western Pyrenees.

Decisive victory: The term decisive victory refers to a military victory in battle that definitively resolves the objective being fought over, ending one stage of the conflict and beginning another stage.
