QUOTE : It took the Soviet security services until the spring of 1950 to track down and kill the commander in chief of the Ukrainian Insurgent Army, Roman Shukhevych. Another commander replaced him, but in the next few years organized resistance was largely crushed, and small underground units lost contact with one another. Some of the insurgent units made their way through Polish and Czechoslovak territories to the West and joined the émigré nationalists led by Stepan Bandera in West Germany. In 1951, the British and the Americans started to airdrop members of the Bandera and other nationalist organizations back into Ukraine with the goal of collecting intelligence. The Soviets responded by stepping up their attempts to assassinate Bandera and other leaders of the Ukrainian emigration in Germany. They succeeded in the fall of 1959, when a Soviet agent killed Bandera with a KGB-made spray gun loaded with cyanide. The assassin defected to the West in 1961 and confessed to killing Bandera and another Ukrainian émigré leader back in 1957. His testimony in a West German court left no doubt that the orders to kill émigré leaders had come from the top echelon of the Soviet government.
