On May 27, it left the Balaguer sector and was assigned to the 3rd Division of the 15th Army Corps, in preparation for its participation in the Ebro offensive. On July 26 it crossed the river 3 km south of Flix as part of the second wave of attack, cooperating with other forces in the capture of this town. Then it continued its advance towards the Sierra de la Fatarella and established its positions in front of Vilalba dels Arcs, the strong point of nationalist forces in the Ebro. It was there that its advance was halted. On August 22 it had to go south of the Gaeta Vertex to plug a gap in the Republican defensive line, which it achieved at the cost of suffering many casualties. A week later it was in the valley of Corbera, but its situation was so compromised that it had to be relieved by troops from the 45th International Division. On October 20, it was permanently withdrawn from the Republican bridgehead to undergo a reorganization, being concentrated in the area of Juncosa-Ulldemolins-Pobla de Ciérvoles.
