Published 80 years after the end of Italian combat operations in Catalonia, "Mussolini's War in Spain 1936-1939" discusses Italian military aid to the Nationalists in the Spanish Civil War. Mr. Cloutier's work draws much from Italian and Spanish publications, followed by Russian publications, as well as such classic Anglosphere historians as Hugh Thomas, Antony Beevor, and John Coverdale. Mr. Cloutier describes Italian operations in detail, often providing a day-by-day picture of events. The Russian-language materials identify the opposing Popular Front (or Republican) units, which engaged Italian and Nationalist units in the struggle for Spain, and are of interest for their assessments of Italian battlefield performance.
