The submitted article is a specific probe into the environment of the Czechoslovak intelligence branch in Istanbul, particularly during 1943. The main restrictions, potential and factors affecting work by Czechoslovak intelligence officers in Turkey are outlined on the basis of information contained in a report from a business trip by intelligence officer Major František Fryč to Istanbul, with the addition of context. The financial issue of the branch and the issue of its primary tasks – the link to the former state of Czechoslovakia and acquisition of information – is particularly important. In order to provide a more accurate description, the staff aspect oft the branch is described along with several specific examples of victory and defeat. Several thematic sections provide us with the opportunity to evaluate the activities of the Istanbul intelligence branch, which remained in the shadows to some degree, on the basis of preserved sources.
