The collapse of the Republican front in Catalonia in early 1939 pushed close to half a million people over the Pyrenees in a few weeks. France interned them on the beaches of Argeles-sur-Mer, Saint-Cyprien and Le Barcares behind wire, at first without shelter or sanitation, and later in camps such as Gurs, Bram and Rivesaltes; thousands died of dysentery, pneumonia and exposure in the first months. Many were pressed into labour companies, and after 1940 Vichy and the German authorities sent almost 9,000 Spanish republicans to Nazi concentration camps; of the 7,288 registered at Mauthausen-Gusen, 4,676 died there. Others returned to Spain, where the Francoist state prosecuted the defeated through military tribunals, held some 270,000 political prisoners at the peak in 1940, used prisoner labour on public works and carried out tens of thousands of executions after the war; that repression, which fell mostly on people who never went into exile, is treated in the atlas's entry on Francoist postwar camps, prisons and forced labour. Spanish and international researchers have documented mass graves still being exhumed under the memory laws of 2007 and 2022.

Spain's 1930 census counted 23,563,867 and the 1940 census 26,014,278; interpolation puts the 1936 population at roughly 24.5 million. The Retirada of January-February 1939 carried about 465,000 people across the French border in a few weeks, of whom roughly half returned to Spain within the year.
This range covers deaths among the exiles only. The lower bound is the 4,676 Spaniards recorded as dying at Mauthausen-Gusen out of 7,288 registered there (the Spanish government's 2019 list named 4,427 Spanish nationals killed at the camp); deaths in other Nazi camps and in the French camps are not included in it. The lower bound is a documented minimum and no upper bound is given: the only figure found for deaths in the French beach camps, some 15,000 from disease and dysentery between February and July 1939, comes from the Pyrénées-Orientales departmental tourism agency's Retirada heritage guide, and no scholarly count exists. Francoist postwar executions (20,000-50,000) are not included: they fell mostly on people who never went into exile and are counted in the entry on Francoist postwar camps, prisons and forced labour. Total deaths in the civil war of 1936-39 are usually put at 500,000 or more and are counted separately.
Internment without charge in the French camps, labour companies, the deportation of Spanish republicans to Nazi camps, the postwar military tribunals and the removal of children from Republican families are documented in French prefectural archives, Mauthausen camp records and Spanish judicial and prison records examined under the historical memory laws.
