The essay concentrates on characteristics of the top Czechoslovak political and military leaders in the late 1920s. They were produced by a Polish military attache in Prague. Their emergence should not be connected with a particular event in the Czechoslovak-Polish relations. However, they were closely related to the tendency of 'shortening' the distance between Warsaw and Prague, which existed in the second half of the 20th century in Polish as well as Czechoslovak military circles. The characteristics are preceded by a clarification of circumstances connected with their emergence and the development of Czechoslovak-Polish relations at that time. The documents contribute to the Polish view on the Czechoslovak political and military leaders in the interwar period.
