Hetty was just twelve years old in 1943 when her family was torn apart following the German invasion of the Netherlands.
Rounded up by the Nazis and then separated from their parents, Hetty and her parents were sent to the Children's House, within Belsen concentration camp. Hetty became the 'Little Mother' of the camp, helping to care for the other children.
This is one of the remarkable, largely untold, stories of the Holocaust - the extraordinary struggle and survival of this group of children through those terrible years.
