With the other women and girls not selected for immediate death, Frank was forced to strip naked to be disinfected, had her head shaved, and was tattooed with an identifying number on her arm. By day, the women were used as slave labour and Frank was forced to haul rocks and dig rolls of sod; by night, they were crammed into overcrowded barracks. Some witnesses later testified Frank became withdrawn and tearful when she saw children being led to the gas chambers; others reported that more often she displayed strength and courage. Her gregarious and confident nature allowed her to obtain extra bread rations for her mother, sister, and herself. Disease was rampant; before long, Frank's skin became badly infected by scabies. The Frank sisters were moved into an infirmary, which was in a state of constant darkness and infested with rats and mice. Edith Frank stopped eating, saving every morsel of food for her daughters and passing her rations to them through a hole she made at the bottom of the infirmary wall.
