In March 1938 the sweeping Aragon Offensive of the rebel faction caught the 26th Division by surprise and the whole unit retreated eastwards to Catalonia without putting any noteworthy fight. Later it was located at the Segre Frontline where it took part in the fruitless Balaguer Offensive in May. Most of the 26th Division remained at the Segre front until the end of 1938, but one of the battalions of the 120th Mixed Brigade of the division was at the Battle of the Ebro.
