On 18 March the division, operating on the right flank of the republican front, and the 11th Division of Enrique Lister, with the support of 70 Soviet T-26 tanks, launched an attack and seized the town of Brihuega; the nationalist forces fled in disarray, leaving behind prisoners and war equipment.
[4][5] By the end of March the front stabilized after the Republicans managed to recover a large part of the territory.
[6] On the morning of 25 July units of the 14th Division launched a counterattack to the southwest of Brunete, counting on the support of Republican aviation.
Once the fighting in Brunete ended, the division returned to the Guadalajara front, where it remained for the following months without intervening in relevant operations.
This was the case of the 70th Mixed Brigade of Bernabé López Calle, which on the morning of 6 March occupied various strategic points in Madrid, such as the Alameda de Osuna, the Ministry of Finance and the Telefónica building.
