Anne, Margot and their mother stay together after their arrival. Auguste van Pels is in another barracks. They have to do heavy work, like carrying rocks. Sometimes they have to stand outside for hours while the Nazis count them. Anyone who is sick is killed in the gas chambers.

At the end of October 1944, Anne and Margot have to leave Auschwitz. The Nazis want to take to Germany as many prisoners as possible who are still able to work. Anne’s mother stays behind. She dies in January 1945 of illness and exhaustion.

At the time of their mother’s death, Anne and Margot are in Bergen-Belsen concentration camp in Germany. The conditions in the camp are appalling. It is overcrowded and there is very little food. Many prisoners become ill and die. A few weeks later, Auguste van Pels arrives in Bergen-Belsen, but on February 6, 1945 she has to move on again. She is sent to Buchenwald concentration camp, but she dies on the way, sometime between April 9 and May 8, 1945.

The conditions in Bergen-Belsen grow even worse. Anne and Margot become desperately ill. Margot is the first to die, in March 1945, and Anne dies a few days later. Bergen-Belsen is liberated by British troops only a few weeks later.
