The battalion first saw combat during the Villarreal Offensive in the Chavalopea del Monte pine forest, in the first days of November 1936.

Although it defended its position and its commander was congratulated by the General Staff, the subsequent defeat was terrible and the battalion suffered more than 200 casualties, including about 100 dead.

At the end of April it helped in the definitive withdrawal from the Gipuzkoan fronts, and at the beginning of May the battalion returned to the area of mount Sollube, on the coast of Vizcaya.

After visiting Solares and Torrelavega, the battalion withdrew to Asturias, where it fought in September and October, standing out in the Battle of El Mazuco.

In July 2006 several members of the battalion participated in a tribute to the Euzko Gudarostea, including Félix Padín Gallo, Marcelino Bilbao and Francisco Alonso Uriarte.
