to travel abroad and contact Russian emigrants. MUCR kept the monarchist general Alexander Kutepov (Александр Кутепов), head of a major emigrant force, Russian All-Military Union (Русский общевоинский союз), from active actions and who was convinced to wait for the development of the internal anti-Bolshevik forces. Among the successes of "Trust" was the luring of Boris Savinkov and Sidney Reilly into the Soviet Union to be arrested. In Soviet intelligence history, the 1930s have proceeded as a so-called Era of the Great Illegals. Among others Arnold Deutsch, Theodore Maly and Yuri Modin were officers leading the Cambridge Five case. One of the biggest successes of Soviet foreign intelligence was the penetration of the American Manhattan Project, which was the code name for the effort during World War II to develop the first nuclear weapons of the United States with assistance from the United Kingdom and Canada. Information gathered in the United States, Great Britain and Canada, especially in USA, by NKVD and NKGB agents then supplied to Soviet physicists, allowed them to carry out the first Soviet nuclear explosion already in 1949. In March 1954, Soviet state security underwent its last major postwar reorganization. The MGB was once again removed from the MVD, but downgraded from a ministry to the Committee for State Security (KGB), and formally attached to the Council of Ministers in an attempt to keep it under political control. The body responsible for foreign operations and intelligence collection activities was First Chief Directorate (FCD). The first head of FCD was Aleksandr Panyushkin, the former ambassador to the United States and China and former head of Second Chief Directorate in MVD responsible for foreign intelligence. Panyushkin's diplomatic background, however, did not imply any softening in MVD/KGB operational methods abroad. Indeed, one of the first foreign operations personally supervised by Panyushkin was Operation Rhine, the attempted assassination of a Ukrainian émigré leader in West Germany. In 1956, Panyushkin was succeeded by his former deputy Aleksandr Sakharovsky, who was to remain head of FCD for record period of 15 years. He was remembered in the FCD chiefly as an efficient, energetic administrator. Sakharovsky had, however, no firsthand experience of the West. Having joined the NKVD in 1939 at the age of thirty, he had made his postwar reputation as an MGB adviser in Eastern Europe, serving mainly in Romania. In 1971, Sakharovsky was succeeded by his 53-year-old former deputy Fyodor Mortin,
