Battle of Valsequillo
The Battle of Valsequillo, also known as Battle of Peñarroya, was a diversionary Republican offensive which took place in the Sierra Morena area in southern Extremadura and the north of Andalusia between 5 January and 4 February 1939 during the Spanish Civil War. The main goal of the offensive was to distract forces from the Nationalist offensive against Catalonia, but after having occupied 500 square kilometers the Republican advance was stopped and all the territorial gains were lost to a Nationalist counteroffensive.
