Umiastowski’s Appeal: on the night of 6 / 7 September 1939 Colonel Roman Umiastowski, head of the propaganda of the Supreme Command of the Polish Army, gave a radio speech in which he called the capable of fighting men to leave Warsaw in order to create a new line of defense east of the Vistula. Volunteers were to be armed and conscripted into the army. Those who followed the appeal stuck on the roads among the crowds of civilian refugees. The appeal also led to a panic among the other people in Warsaw, since it suggested that the capital would be given to Germany without a fight.
The term was created within the framework of the project Zapisywanie świata żydowskiego w Polsce [recording the Jewish environment in Poland], whose author is Anka Grupińska, a well-known Polish journalist and writer, specializing in the modern history of the Polish Jews. The project, initiated in 2006 by the Museum of the History of Polish Jews, consists in recording interviews with Polish Jews from all generations.
