History of military intelligence - period of the First Republic
The greatest success against the Hungarian intelligence activities was a long-term operation lay in gaining information on Hungarian agency network activities in our territory. The information was taken from the correspondence of the Hungarian military attaché General Ujzazy. The Czechoslovak counter-espionage service, on the base of the operation, prepared incriminating materials, which were proposed to general Ujzazy by major Bartík in Budapest after the occupation of Sudeten in autumn of 1938. The materials won general to work for activities in favor of the 2nd Department of the Czechoslovak Main Staff. The importance of the step was raised by the fact that General Ujzazy was since his arrival from Czechoslovakia to Budapest in 1938 to his death in 1941 a head of the Hungarian Military Intelligence Service. Since the 2nd Department could not use service of the General after the occupation of Czechoslovakia effectively, it handed him over to the British intelligence service.
The search group of the 2nd Department of the Main Staff controlled also agent A-53, who was a member of the Third Reich Army. He provided information on German plan of sharp and resolute attack of Czechoslovakia in case a war conflict between Germany and France emerges.
An interesting activity of the 2nd Department was establishment of imaginary company - banking institution in Ústí nad Labem, which was used especially for estimating potential agents chosen from the inhabitants of the Third Reich for the Czechoslovak military intelligence. The bank was active during 1934-1936 and had approximately 90 employees. The principle was based on providing loans to the German inhabitants, which preferred the Czechoslovak bank because their demand for money could raise suspicion to security organs in the Third Reich. The debts were mostly from hazard and because of involvements outside marriage, and which had state officials and members of the Third Reich Military Service. Activities of the Cover Company allowed the Czechoslovak intelligence to recruit a number of agents in the Third Reich. The final number of gained agents and estimated persons was in hundreds.
