Krystyna Czyż was one of the Rabbits of Ravensbrück—young women subjected to brutal medical experiments by Nazis. She found ways to resist, even in the face of death. Using urine as invisible ink, she and others smuggled coded messages to the outside world, exposing the horrors inside the camp.

She was not alone in her bravery. Among the prisoners were members of the Girl Guides (basically the Girl Scouts), young women who upheld their promise to serve and protect others, even in a concentration camp. They cared for the sick, smuggled food, and kept hope alive.

Through small acts of defiance—messages written in urine and quiet acts of kindness—these women proved that even in the darkest places, courage and sisterhood could not be silenced.

Originally, I intended to detail some of the atrocities faced by the Rabbits of Ravensbrück, but one of the women left a letter hoping that no one would remember the evil deeds done to them, but instead remember their resilience, courage, and the strength of friendship- a message reiterated by those who survived Ravensbrück.

Edited to add: Krysia went on to become an academic.
