On an icy morning in Paris in January 1943, 230 French women resisters were rounded up from the Gestapo detention camps and sent on a train to Auschwitz--the only train, in the four years of German occupation, to take women of the Resistance to a death camp. The youngest was a schoolgirl of 15, the eldest a farmer's wife of 68; among them were teachers, biochemists, salesgirls, secretaries, housewives and university lecturers. Six of the women were still alive in 2010 and able to tell their stories of the great affection and camaraderie that took hold among the group. They became friends, and it was precisely this friendship that kept so many of them alive.
