Fourteen Basque prisoners were shot by the Francoists at El Dueso prison in Santoña. In mid-August, as a result of negotiations between the Basque Government and Italians, the Basque Army surrendered in Santoña in exchange for forgiving and evacuating life. The Francoists, however, did not speak and were imprisoned. As a disciplinary measure, they merged two representatives from each Basque training, nationalists, republicans, socialists, communists and anarchists.
