The Mickiewicz Battalion was a volunteer battalion of the International Brigades during the Spanish Civil War.

In July 1938 The Battalion took part in the Battle of the Ebro crossing the river and initially advancing quickly attacking and capturing many Nationalist troops at La Venta de Camposines, before moving on to near Gandesa.{{cite book |last1=Tremlett |first1=Giles |title=The International Brigades |date=2020 |publisher=Bloomsbury Publishing |location=London |isbn=978-1-4088-5398-6 |pages=473–474}} By September 1938 they were dug in defending a difficult position on the road from Corbera d'Ebre under constant bombardment and machine gun fire, the only respite being at night. They continued to dig trenches and lay barbed wire. After an artillery bombardment, the Battalion continued a heroic defence against tanks and cavalry which saw many of their best men killed, before the order for withdrawal came.Tremlett (2020) p.503-504
