Over 100 Dutchmen were sent to their deaths at a secret Nazi gas chamber in 1941, a year before Nazis began mass deportations of Jews to gas chambers.
The men were seized in Amsterdam in the Netherlands in February 1941, in the first Nazi raids on Jews in Western Europe, and sent to Mauthausen concentration camp in Austria.
Historian Wally de Lang says 108 were murdered at the nearby Hartheim Castle.
They were given fictitious causes of death, she explains.
Germany invaded the Netherlands in May 1940 and over the next five years more than three-quarters of the Jewish population were murdered, with deportations to the extermination camp at Auschwitz beginning in July 1942.
