The paper is a part of the war diary of Aurelia Wyleżyńska (1881-1944), in which she described the political and social life in Warsaw (and not only there) from September 1939 until June 1944. Aurelia Wyleżyńska, a scion of Polish gentry, was a writer and journalist, the author of over a dozen of novels and hundreds of articles in Polish and French-language press, concerning mainly literature, feminism, pacifism (and civilizational progress, which she identified with the latter). She investigates the mood of the civilians and the views of Polish soldiers she met. She analyses social conditions, including her Jewish friends. She shows the dreadful German invasion and the accompanying changes to life and death. She also comments on the Soviet invasion. In her diary she shows how quickly the bustling Polish capital turns into a ruined cage for individuals struggling for survival.
