Invasion of Val d'Aran
The Invasion of Val d'Aran, known under the code name "Operación Reconquista de España" ("Operation Reconquest of Spain"), was a military operation launched in October 1944 by the Unión Nacional Española (antifrancoist) () (UNE). In October 1944, with the Spanish Civil War over and the Axis powers in World War II in retreat, guerrilla fighters loyal to the Republic tried to conquer Val d'Aran in Catalonia and establish a provisional Republican government presided over by Juan Negrín in order to later defeat the dictatorship of Francisco Franco. However, the Francoist army was able to repel the invasion.
