In Paris, January 1943, 230 French women resisters were rounded up 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; there were among them teachers, biochemists, sales girls, secretaries, housewives and university lecturers. The women turned to one another, finding solace and strength in friendship and shared experience. Forty-nine of them came home. Drawing on interviews with survivors and their families, on archival research and original sources, A Train in Winter covers a harrowing part of our history but is, ultimately, a portrait of ordinary people, of bravery and endurance.
