Vel' d'Hiv Roundup

The Vel' d'Hiv' Roundup was a mass arrest of foreign Jewish families by French police and gendarmes under the orders of German authorities. It took place in Paris on 16 and 17 July 1942. 13,152 Jews were arrested, including more than 4,000 children.
In the week following the arrests, the Jews were taken to the Drancy, Pithiviers, and Beaune-la-Rolande internment camps, before being shipped to Auschwitz for their mass murder.
