Sisters supported the local community not only with their prayer and the conversation, but also with charity works, sending parcels to the deported into far end of Russia, preparing children for the First Communion and carrying on the clandestine teaching of Polish literature and history at homes.
At night around 17 on 18 July 1943, in retaliation for attacks launched by guerrillas, Gestapo carried out mass arresting. More than 120 prisoners were destined to be executed. Sisters together took the decision of giving their life for the imprisoned expressed by Sister Stella the superior, who shared the Sisters' decision with their chaplain, saying:
"My God, if sacrifice of life is needed, accept it from us and spare those who have families. We are even praying for this intention."
On 31 July 1943 Sisters were ordered to turn up during the evening, at 7.30 pm. at the Gestapo headquarters. The sisters' sentence had already been decided. They spent a night on the prayer in a little basement of Gestapo headquarters and then on August 1, 1943, on Sunday at dawn they were exported to a nearby forest and executed by a firing squad. God accepted the sacrifice. Almost as an immediate response to the Sisters' offering of life, miraculously, though it's difficult to explain why, the capital punishment for the imprisoned people was changed and they were deported to work camps in Germany. Some of them were even released. After the war all went back home.
On 5 March 2000, in Rome, the Holy Father John Paul II, beatified Sister Maria Stella and her 10 Companions, giving them to us as the model of love and the defence against the evil's attacks threatening the contemporary family.
