Karoly Schandl in Budapest, 1956




The Following Secrets of Stalin's Soviet Prisons are revealed in  SWORD OF THE TURUL, based on a survivor's memoirs and recollections ...



Prisoners kept in the secret special section were bombarded  with ultrasonic sounds in different languages.


The ultrasonic sounds would often be based on what the NKVD operators of the system had learned from the hidden microphones in the cells.


Not all prisoner interrogations were recorded.


“Trials” were at night and defendants were not given a chance to speak.


Kitchen helpers were believed by many to be prison informants.


The worst prison was Lefortovo. Lubyanka was considered less dingy.


Vladimir prison, the maximum security prison for high profile prisoners, was where the Soviets secretly held members of the anti-Nazi resistance from World War II - and even an American they'd abducted in Vienna, Austria.





Excerpt From SWORD OF THE TURUL, by Catherine Eva Schandl

           "I knew that the sounds were the product of an outside source, and not creations of my own, because I heard them initially in Russian, a language I did not understand or speak at the time.

            Later I made some tests. I had to listen for hours one morning to the voices of some women in German (which I spoke). ‘Good morning, Second Lieutenant,’ was repeated about a  hundred times, then changed to ‘Good morning, Lieutenant  Colonel’ again for 15-20 minutes, then ‘You are the greatest man  in the world,’ changed to ‘You are the nicest man in the world.’

             Out of boredom, I started to repeat back, in front of the enclosure for the central heating, where the voices appeared to be the strongest: ‘You are the nicest women in the world …’ (also in German). For a moment there was silence. I was relieved; at least I knew I was not mad. Then a burst of laughter followed – they were laughing. And strangely enough, I heard the laughter not only through the ‘system’ but also from outside, the corridor, from the direction of the center of the prison. Then they went on with their monotonous text.

             When food was distributed, they came with different pots, and the sergeant watched carefully that every prisoner should get the type of food prescribed for him ..." (Karoly William Schandl)
