Hungarian Uprising of 1956

"Numerous published accounts have indicated the existence of secret U.S.-trained émigré groups in the 1950s identified under such rubrics as Red Sox/Red Cap or the Volunteer Freedom Corps. But it has never been officially confirmed whether any groups of this kind played a part in Hungary in 1956. From the Clandestine Service Histories, it seems clear they did not. Although the new documents confirm that small psychological warfare and paramilitary units came into being in the early 1950s, (including the Hungarian National Council headed by Bela Varga), and occasional reconnaissance missions took place at that time, the prospects for penetrating into Hungary deteriorated by 1953 when stepped up controls by Hungarian security forces and "the meager talent available" among potential agents made cross-border operations essentially untenable."
