Dokument czechosłowackiego wywiadu wojskowego o współpracy z Oddziałem II Sztabu Głównego Wojska Polskiego z 1934 roku

During the interwar period, Polish-Czechoslovak intelligence cooperation developed well. It mainly concerned the recognition of Germany’s military potential. Collaboration between the two intelligence services consisted primarily of joint intelligence conferences. It was discontinued for political reasons resulting from Warsaw and Prague’s different concepts of how to ensure the security of the state and the lack of an agreement between Poland and Czechoslovakia.
