It also participated in the Battle of Valsequillo, the last republican offensive of the civil war. It intervened from the first day of the offensive, on 5 January, in the second wave, occupying various heights. When it tried to progress on day 6, it encountered strong resistance in Mano de Hierro and El Médico that it could not overcome, thus preventing the widening of the rupture zone. In later days it tried to overcome this resistance by attacking the rear in Sierra Tejonera, but it was arrested after heavy fighting. The operation ended in a failure on 2 February.
