Vilnius was taken over by the Germans on 24 June 1941, in Operation Barbarossa, and the killing of the Jews began almost immediately. Mother Betranda first inquired about saving Jews following the start of the Ponary massacre in July 1941. She initially sought to gain the support of the Wilno Catholic leadership, but they rebuffed her efforts out of fear that the Nazi Germanoccupation forces would destroy church property and kill any Christians found to be aiding Jews. Acting on her own initiative, Mother Betranda then took in 17 members of Hashomer Hatzair, a local Zionist group, and hid them within the grounds of her monastery. The activists included Abba Kovner, the movement's leader, Abraham Sutzkever, Arie Wilner and Edek Boraks. They helped the nuns with working their fields, while Kovner, realizing the goals of Hitler's Final Solution, worked on organizing a political resistance to the occupation and writing his manifesto for the later uprising. When several of her nuns objected, Mother Bertranda reportedly threatened them with expulsion from the monastery and excommunication from the faith. Some of the Hashomer Hatzair members later decided to leave their monastery hideout and to return to the Jewish Ghetto in Vilnius, where they organized an underground resistance movement, the Fareynikte Partizaner Organizatsye.
Soon after that, Mother Bertranda left the monastery and went to the Ghetto to volunteer her services. She was dissuaded from this by Kovner, who asked that she organize the procurement of supplies instead. She and the other Dominican nuns then took it upon themselves to help the Jewish resistance by smuggling in arms and ammunition. The other nuns of the community included Sister Bernadeta, Sister Cecylia, Sister Diana, Sister Imelda, Sister Jordana, Sister Małgorzata and Sister Stefania. In this they became among the first to supply hand grenades and other weapons to the Vilnius Ghetto underground. Between August and September 1943, the ghetto was liquidated and some 12,000 men, women and children were deported to camps in Estonia. The uprising, organized by FPO on 1 September 1943 was crushed. The final Nazi destruction of whatever remained of the Ghetto followed. In September 1943, Mother Bertranda was arrested by the Nazi German occupation authorities and sent to a labor camp at Perwejniszki near Kovno. The monastery was closed and the community of nuns was forced to disperse. After the war, Mother Bertranda asked for a dispensation from her vows and left the monastery, where she adopted the name Anna Borkowska.
Recognition
In 1984, Borkowska, now living alone in a small apartment in Warsaw, was awarded the title of Righteous among the Nations by Yad Vashem. Abba Kovner, one of the young Jews who had been saved by Borkowska, personally presented a medal to her at a ceremony in Poland. She and Cecylia Roszakcan were two members of this monastic community to be honored, according to the statistics given by Yad Vashem.
