[1] Before the Nazi German invasion of Poland in 1939, Dzierżązna was the location of a large estate owned by two lawyers from Łódź, with a spacious manor house built by one of them.

In 1942 the manor house was appropriated by the German police, who established a concentration camp on premises for Polish girls 8–16 years of age.

[2][3] The girls' camp was a sub-camp of the main camp for Polish children in Łódź called Kinder-KZ Litzmannstadt (full name in German: Polen-Jugendverwahrlager der Sicherheitspolizei in Litzmannstadt), operated from January 1943 till January 1945.

[4] Polish girls were prepared in Dzierżązna for slave labour on German farms in the Reich, under the command of SS Aufseherin Sydomia Bayer [pl] (b.1903-hanged 12 November 1945 Poland).

[5] She is known to have killed at least one of the little girls, named Urszula Kaczmarek, by flogging her to death in front of other children.
