Rhodes went to Hungary when news broke of the uprising in 1956. He likely supplied British Intelligence with reports during this period as well as writing articles on the crisis for the "Daily Telegraph". He recounted this period in his subsequent book, "Journey to Budapest". His biography of the 19th-century Italian writer and proto-Fascist Gabriele D'Annunzio, was published in 1960 under the title "The Poet as Superman". Another biography, this time of the French car manufacturer Louis Renault, who collaborated with Hitler, was published in 1969. In 1976 he published with Victor Margolin "Propaganda - The Art of Persuasion: World War II" (reprinted 1993).
