Operation Bolívar was the codename for the German espionage in Latin America during World War II. It was under the operational control of Department VID 4 of Germany's Security Service, and was primarily concerned with the collection and transmission of clandestine information from Latin America to Europe. Overall, the Germans were successful in establishing a secret radio communications network from their control station in Argentina, as well as a courier system involving the use of Spanish merchant vessels for the shipment of paper-form intelligence.
