context_page_description: The Office of Strategic Services was a wartime intelligence agency of the United States during World War II, and a predecessor to the Department of State's Bureau of Intelligence and Research and the Central Intelligence Agency. The OSS was formed as an agency of the Joint Chiefs of Staff to coordinate espionage activities behind enemy lines for all branches of the United States Armed Forces. Other OSS functions included the use of propaganda, subversion, and post-war planning. On December 14, 2016, the organization was collectively honored with a Congressional Gold Medal.
context_section_description: OSS proved especially useful in providing a worldwide overview of the German war effort, its strengths and weaknesses. In direct operations it was successful in supporting Operation Torch in French North Africa in 1942, where it identified pro-Allied potential supporters and located landing sites. OSS operations in neutral countries, especially Stockholm, Sweden, provided in-depth information on German advanced technology. The Madrid station set up agent networks in France that supported the Allied invasion of southern France in 1944. Most famous were the operations in Switzerland run by Allen Dulles that provided extensive information on German strength, air defenses, submarine production, and the V-1 and V-2 weapons. It revealed some of the secret German efforts in chemical and biological warfare. Switzerland's station also supported resistance fighters in France and Italy, and helped with the surrender of German forces in Italy in 1945.
  For the duration of World War II, the Office of Strategic Services was conducting multiple activities and missions, including collecting intelligence by spying, performing acts of sabotage, waging propaganda war, organizing and coordinating anti-Nazi resistance groups in Europe, and providing military training for anti-Japanese guerrilla movements in Asia, among other things. At the height of its influence during World War II, the OSS employed almost 24,000 people.
  From 1943–1945, the OSS played a major role in training Kuomintang troops in China and Burma, and recruited Kachin and other indigenous irregular forces for sabotage as well as guides for Allied forces in Burma fighting the Japanese Army.  Among other activities, the OSS helped arm, train, and supply resistance movements in areas occupied by the Axis powers during World War II, including Mao Zedong's Red Army in China (known as the Dixie Mission) and the Viet Minh in French Indochina. OSS officer Archimedes Patti played a central role in OSS operations in French Indochina and met frequently with Ho Chi Minh in 1945.
  One of the greatest accomplishments of the OSS during World War II was its penetration of Nazi Germany by OSS operatives. The OSS was responsible for training German and Austrian individuals for missions inside Germany. Some of these agents included exiled communists and Socialist party members, labor activists, anti-Nazi prisoners-of-war, and German and Jewish refugees. The OSS also recruited and ran one of the war's most important spies, the German diplomat Fritz Kolbe.
  From 1943 the OSS was in contact with the Austrian resistance group around Kaplan Heinrich Maier. As a result, plans and production facilities for V-2 rockets, Tiger tanks and aircraft (Messerschmitt Bf 109, Messerschmitt Me 163 Komet, etc.) were passed on to Allied general staffs in order to enable Allied bombers to get accurate air strikes. The Maier group informed very early about the mass murder of Jews through its contacts with the Semperit factory near Auschwitz. The group was gradually dismantled by the German authorities because of a double agent who worked for both the OSS and the Gestapo. This uncovered a transfer of money from the Americans to Vienna via Istanbul and Budapest, and most of the members were executed after a People's Court hearing.
  In 1943, the Office of Strategic Services set up operations in Istanbul. Turkey, as a neutral country during the Second World War, was a place where both the Axis and Allied powers had spy networks. The railroads connecting central Asia with Europe, as well as Turkey's close proximity to the Balkan states, placed it at a crossroads of intelligence gathering. The goal of the OSS Istanbul operation called Project Net-1 was to infiltrate and extenuate subversive action in the old Ottoman and Austro-Hungarian Empires.
  The head of operations at OSS Istanbul was a banker from Chicago named Lanning "Packy" Macfarland, who maintained a cover story as a banker for the American lend-lease program. Macfarland hired Alfred Schwarz, a Czechoslovakian engineer and businessman who came to be known as "Dogwoo
