After the German Socialists invaded and occupied Poland, Mother Superior Kazimiera "Maria Marta od Jezusa" Wołowska hid and gave shelter to Jewish children in the Sisters of the Immaculate Conception of the Blessed Virgin Mary convent, in Słonim.
In the middle of the night, of December 18, 1942, Gestapo forced their way into the convent, conducted a search, and found where the Jewish children were hidden.
That night, Mother Superior, Sister Bogumiła "Maria Ewa of Opatrzność" Noiszewska (a medical doctor) and Jesuit Father Adam Sztark were arrested.
The following morning, December 19, 1942, the three were stripped of their religious garb and taken to Pietralewicka Hill near Słonim, where they prayed the rosary and sang religious songs at a large pit.
Father Sztark granted absolution to all before they were forced to lie down, head to head, and executed by gunshots and grenades.
"Father, forgive them, for they do not know what they do," were Mother Superior's last words.
