The Battle of the Baztan Valley was fought between 23 July and 1 August 1794 during the French Revolutionary War, between a French force from the Army of the Western Pyrenees commanded by Bon-Adrien Jeannot de Moncey and the Spanish forces led by Don Ventura Caro. The French army drove the Spanish from their defenses, then followed the valley northward to the Atlantic coast. The Spanish forces holding the coastal defenses were compelled to surrender or flee.
