On this day in 1941, 3,600 Jews were arrested in Paris, France. Known as the rafle du billet vert, or ‘Green Ticket Roundup’, the event began after French police delivered green tickets to 6,694 foreign Jews living in Paris, instructing them to report for a status check. Roughly half of those summoned, most of whom were Polish and Czech Jews, obeyed because they assumed the gathering was purely administrative. They were immediately arrested, and those who accompanied them were instructed to gather a list of supplies, including blankets, clothes, cutlery, and food, among other items.The men summoned for the roundup were transferred to the Pithiviers and Beaune-la-Rolande internment camps in German-occupied France, where the prisoners were subjected to forced labor. Both camps were initially French-run, but the Germans took over operations in 1942. The prisoners were held for over a year without knowing what would happen to them. Beginning in May 1942, prisoners of the Green Ticket Roundup began to be transferred to other transit camps around France. By June, they were transported to Auschwitz on convoys 2, 4, 5, and 6. The Green Ticket Roundup remains in historical memory as the first roundup of Jews under the Vichy regime. 700 Jews in the roundup were able to escape, but the rest were murdered at Auschwitz.
