On March 9, 1938, after the start of the nationalist offensive on the Aragon front, the brigade was ordered to march to the threatened sector to try to contain the enemy attack.[8] On March 11, however, the brigade disbanded due to contact with the enemy in the area of Alagón-Oliete. On March 13, it lost the towns of Andorra, Ariño and Alloza, having to retreat to the area between Teruel and Escorihuela, where it was located until April 23rd. Its remains ended up being reintegrated into the old division.[9] The 127th Brigade, which suffered a major loss, had to be withdrawn to Calles to undergo a reorganization.[10]
In August 1938 it was sent as reinforcement to the Extremadura front, now under the command of the militia major Esteban Serra Colobrans. The brigade intervened in the Republican counterattack that followed the Franco offensive in the Battle of Merida pocket. After crossing the Zújar river, it continued advancing until it was in the vicinity of Castuera. It remained in this sector until it was withdrawn to cover losses suffered. In January 1939 it intervened in the Battle of Peñarroya, participating in the breakdown of the front and managing to advance to the Patuda and Trapera mountains. The unit was dissolved at the end of the war.[n. 2]
