This article analyses the novels of Blue Division which were written between the 50s and the 70s by war veterans. They were focusing on the showing of authors and characters’ disillusion, and on the reasons of the arising of this frustration feeling amongst the most purist activists of Spanish Falange. The frustrated idealism of the authors and their protagonists led those novelists to an evident intimate retreat, whose effects will be analysed in the study of the novels of Rodrigo Royo, Tomás Salvador, Carlos María Ydígoras and Eleuterio Paniagua.
