Perhaps its most spectacular success was the Trust Operation of 1924–1925. OGPU agents contacted émigrés in western Europe and pretended to be on a large group working to overthrow the communist regime, known as the "Trust". Exiled Russians gave the Trust large sums of money and supplies, as did foreign intelligence agencies. The Trust finally succeeded in luring one of the leading anti-Communist operators, Sidney Reilly, into Russia to meet with the Trust. Once he was in Russia, he was captured and killed. It was a great propaganda success.
