Agnieszka Dowbor-Muśnicka (7 September 1919 – 20 or 21 June 1940) was active in the Polish resistance against Nazi occupiers in World War II and was murdered in the Palmiry massacre.

[1][2][3] When she was 21, German forces occupied Poland and Agnieszka fled to Warsaw becoming an active member of the Polish resistance and joining an organization called "the Wolves."

While underground, she used her nickname Gusia to hide her real identity because the Gestapo was already looking for her because she was the daughter of the famous general and member of the intelligentsia.

[2][4] Agnieszka reported to the group leader, a former Polish Olympic athlete Janusz Kusociński,[2][4] but she was arrested on 25 April 1940 and imprisoned in the Pawiak prison near Warsaw along with other activists of the Wolves center.

Janina had served as a pilot and lieutenant in the Polish air corps and was murdered on her 32nd birthday during the Katyn massacre by forces of the Soviet Union.
