Le réseau Sorge examines the activities of Richard Sorge, the German journalist who operated as a Soviet intelligence officer in Tokyo before and during World War II. Drawing on declassified documents, personal testimonies, and historical analysis, Gordon W. Prange traces how Sorge supplied Moscow with crucial information about German and Japanese military intentions, including the timing of Operation Barbarossa and Japan’s decision not to attack the Soviet Union in 1941. The narrative explores the intricate web of contacts Sorge cultivated among diplomats, businessmen, and journalists, highlighting both his successes and the eventual betrayal that led to his arrest, trial, and execution. Prange situates the spy ring within the broader context of wartime espionage, assessing its impact on Allied strategy and the eventual outcome of the conflict. The book combines rigorous scholarship with a compelling storytelling approach, offering readers insight into one of the most significant intelligence operations of the twentieth century.
