[6] The international units under "General Walter" soon took Codo town, where 300 fanatical Carlist troops holed up and put up a fierce fight against the two thousand attacking Republican soldiers.

[7] When the brigades entered Codo they saw a wall defaced with the words: "Por cada rojo que máteis, un año menos de purgatorio" (For every Red you kill, one year less in purgatory).

At the end of December the division went to the Teruel Front in order to try to curb the Francoist counterattack which was threatening the small city which had been conquered by the Republicans at a high cost in human lives.

Unable to face the powerful enemy thrust the division had to withdraw to La Muela Hill, a position which it defended fiercely during the following few days until it moved down to the Singra sector.

The British, American and Canadian men of the XV International Brigade were the last to leave Belchite, by then a ruined place, which they had conquered at such high cost in human lives and materiel the previous summer.

On 17 March, despite the international units putting up a brave resistance, Caspe fell to the enemy and the Republicans initiated a massive withdrawal towards Catalonia and the Levant.

[15] At the beginning of April the 35th Division entered Catalonia where it would be cut off from the remaining Republican territory to the southwest when the rebels reached the Mediterranean shore at Vinaròs (north of Castellón Province).

[17] It reached the Venta de Camposines, taking Corbera d'Ebre and the outskirts of Gandesa, becoming the Republican division that made the most spectacular advance in territory previously controlled by the rebels in the whole battle.

[19] The division held its positions around Corbera until the fourth Francoist counteroffensive, when it was forced to move north by the rebel advance and had to cross back the Ebro east of Fayón by mid November, being the last Republican unit to withdraw.

[20] For an anguishing period of twelve days the last remnants of Republican elite troops in Catalonia were able to contain the fierce attacks of the Fascist Italians of the Corpo Truppe Volontarie (CTV), but on 5 January the loyalist resistance crumbled and there was a general debacle.
