Even though in 1941 Zofia's father was killed in a Soviet air-strike on Warsaw — from winter of 1941 till August 1944 (when the Warsaw Uprising started) — the two women managed to rescue at least fifty (50) Jews in their home, including a family of ten, escaping the Ghetto firestorm in April 1943 following the failed Ghetto Uprising. When their house was full, the Banieckis helped Jews find other places to hide.
