Madrigueras and the International Brigades Curiosity · Madrigueras, La Manchuela, Albacete Image of Madrigueras, not of the place itself. The municipality of Madrigueras took in units of the International Brigades during the Civil War; inscriptions and drawings by volunteers from 1937 and 1938 were preserved in the cells of its Brigades' prison. Over the course of the conflict, these units brought together foreign volunteers from more than fifty countries, most of them workers recruited by the communist parties or veterans of the First World War rather than professional soldiers; the French were the largest contingent, with close to ten thousand men, many of them arriving from Paris. The Brigades fought in the defence of Madrid and in the battles of the Jarama, Guadalajara, Brunete, Belchite, Teruel, Aragon and the Ebro, before being withdrawn from the front on 23 September 1938.
