The Frank family goes into hiding for two years. The hiding place was known as the "Secret Annex".
A German secret police officer accompanied by four Dutch Nazis stormed into the Secret Annex and arrested everyone hiding there.
The residents of the Secret Annex were shipped off to Camp Westerbork, a concentration camp in the northeastern Netherlands, and arrived by passenger train.
They were transferred to the Auschwitz death camp in Poland in the middle of the night.
Anne and Margot were again transferred during the winter to the Bergen-Belsen concentration camp in Germany.
Frank and her sister both came down with typhus in the early spring and died within a day of each other sometime in early March, only a few weeks before Russian soldiers liberated the camp.
