49 returned; she wrote about this experience later in Le convoi du 24 janvier (published in English as Convoy to Auschwitz). Other Frenchwomen of note on that convoy were Marie-Claude Vaillant-Couturier, daughter of magazine editor Lucien Vogel and Communist Resistance activist, who would later testify at the Nuremberg Trials of war criminals; France Rondeaux, a cousin of André Gide; Vittoria "Viva" Daubeuf, daughter of Italian socialist leader and future deputy prime minister Pietro Nenni; Simone Sampaix, daughter of the editor of L'Humanité; Marie "Mai" Politzer, wife of sociologist Georges Politzer; Adelaide Hautval, a doctor who would save many inmates and testify against Nazi medical atrocities; and Hélène Solomon-Langevin, daughter of physicist Paul Langevin. It was partly thanks to the presence of several scientists among the prisoners (others were Laure Gatet and Madeleine Dechavassine) that a few, Delbo included, were selected to farm kok-saghyz and survived. Most of the women on the convoy, however, were poor and uneducated and nearly all Communists. One of their number, Danielle Casanova, would be eulogized as a Communist martyr and role model for many years. Delbo later debunked much of the Casanova legend. She paid more tribute to her working-class friends such as Lulu Thevenin, Christiane "Cecile" Charua (later married to historian and Mauthausen survivor Jose Borras), Jeannette "Carmen" Serre, Madeleine Doiret, and Simone "Poupette" Alizon, many of whom figure prominently in her memoirs. The women were in Auschwitz, first at Birkenau and later the Raisko satellite camp, for about a year before being sent to Ravensbrück and finally released to the custody of the Swedish chapter of the International Red Cross in 1945 as the war drew to a close. After recuperating, Delbo returned to France. After the war She wrote her major work, the trilogy published as Auschwitz and After ("None of Us Will Return", "Useless Knowledge" and "The Measure of Our Days,") in the years immediately after the war but held off on publishing the first part until 1965 to give the book the test of time, because of her fear that it would not do justice to the greatest tragedy humanity had known. The final volumes were published in 1970 and 1971. The play "Qui Rapportera Ces Paroles?" (Who Will Carry the Word?) is about Delbo's experience at Birkenau. In later years, she abandoned Communism, influenced like other resistor-survivors (David Rousset and Jorge Semprún among them) by the exposure of concentration
