Green ticket roundup

The green ticket roundup (or green card roundup; ) is the name given to the summons and arrest of foreign Jews in France by French police on 14 May 1941.
Although called by this name, it was not actually a "roundup" since the summons were mailed, and those who responded reported to an assembly point on their own. Those who appeared as ordered were arrested, and deported to one of two transit camps in France. From there, the great majority were shipped to Auschwitz where they were killed.
Terminology.
This event is called in French. Scholarship in English has tended to use one of three terms for this topic: either "green ticket roundup", "green card roundup", or the original French term to discuss the event. "Green" is part of the name in all sources, which report that the summons that was sent to foreign Jewish residents of the Paris region was printed on green paper or green card stock. The word can be translated in various ways, in this context, usually "ticket" or "card". 
The event is known as a "roundup" both in French () and in English, although the term "roundup" is not strictly accurate, since the victims responded to a mailed summons. However, it has become the conventional term to use for this event, because it was the first of a wave of massive arrests of Jews under the Vichy regime, of which the remaining ones were mostly roundups. In particular, it occurred before the larger Vel' d'Hiv Roundup of July 1942.
Background.
France fell in World War II to the German invasion which began in May 1940 and ended with the occupation of Paris on June 14 and capitulation to Germany eight days later. France was occupied by Nazi Germany and divided in two, with the north and west (including Paris) belonging to the Occupied zone administered directly by Germany, and the rest to the so-called" Zone libre" ("Free zone") in the south and east. The French government under Marshall Philippe Pétain moved to the town of Vichy in the . On July 10, parliament dissolved itself, ending the Third Republic and creating the "French State" (; more commonly known as the "Vichy regime") in its place with Petain holding supreme power. 
Starting in 1940, the Vichy government voluntarily adopted, without coercion from the German forces, laws that excluded Jews and their children from certain roles in society. According to Marshal Philippe Pétain's chief of staff, "Germany was not at the origin of the anti-Jewish legislation of Vichy. That legislation was spontaneous and autonomous."
Rudolph Schleier, the German Consul General in Paris wrote in a report to Berlin, "The French government has undertaken to send all foreign-born Jews to concentration camps in the Unoccupied Zone," and continued that "[Jews] will be arrested in the Occupied Zone the moment the necessary camps are ready." By 1941, the camps at Pithiviers, Beaune-la-Roland, Compiegne, and Drancy were in operation, chiefly for the purpose of interning foreign Jews from Paris.
In July 1940, Vichy set up a special commission charged with reviewing naturalisations granted since the 1927 reform of the nationality law. Between June 1940 and August 1944, 15,000 persons, mostly Jews, were denaturalised. This bureaucratic decision was instrumental in their subsequent internment.
In , French authorities performed a census of foreign Jews by order of the Germans. In October, the Vichy regime then took the initiative to promulgate a new law on the status of Jews. Theodor Dannecker, representative of Adolf Eichmann in Paris, wished to speed up the exclusion of Jews, not only by registering them and plundering their goods, but also by interning them. He counted on Carltheo Zeitschel at the German embassy in Paris, who shared the same objectives, and who was in charge of relations with the Commissariat-General for Jewish Affairs, which was created on .
On , Dannecker informed Prefect Ingrand, representative of the Ministry of the Interior in the Occupied zone, of the transformation of the prison camp of Pithiviers into an internment camp, with the transfer of its management to French authorities. At the same time, the Germans insisted on implementation of the law which allowed the . The camp at Pithiviers being insufficient for the purpose on its own, the Beaune-la-Rolande internment camp was needed as well, for a total capacity of 5,000 detainees.
Operations.
On the basis of censuses, 6694 foreign Jews, mostly Polish males between 18 and 60 years old living in the Paris region, received a summons on a green card (the ) hand-delivered by a French policemean for a "status review" (". The green cards ordered them to go to Parisian police stations on , accompanied by a relative. The card read:
More than half (3747) obeyed the summons, because they thought it was only an administrative formality, and were immediately arrested; while the person accompanying them was requested to go fetch their belongings and food. They were transferred by bus to the Paris Austerlitz railway station and deported the same day by four special trains to the internment camps of the Loiret department, about 1700 in Pithiviers and 2000 in Beaune-la-Rolande.
Fate of the deportees.
Between and , about 800 prisoners managed to escape but they were often recaptured. The overwhelming majority of the victims of the operation were deported in the first of June and July 1942 and murdered at Auschwitz concentration camp.
