Most researchers describing operational plans of the Polish People’s Army rely on materials produced by the General Staff of the Polish Army and other central institutions of the Ministry of National Defense. Using the files of the Command of the Warsaw Military District, the author depicts the research potential of documentation created by lower-ranking institutions and units. The article reviews the contents of the 1969 file titled “Issues of the military theater. Map of transport networks in the French coastal operational direction”. The file contains an analysis of the road and train networks on the northern coast of France, created by planners of the Polish People’s Army, as well as a map on which place names are written phonetically. The file also includes a number of documents discussing issues going beyond those referred to in the title, such as an overview of the French military education system and difficulties with procuring valuable candidates. Another document presents the characteristics of the French officer corps and the problems plaguing it. The file also includes a study prepared by the Polish military concerning American and Israeli air forces. The analysis of the activity of the American army in Vietnam is particularly noteworthy, as it recognizes the use of drones.
