Petain and the Vichy regime willfully collaborated with the German occupation to a high degree. The French police and the state Milice organised raids to capture Jews and others considered "undesirable" by the Germans in the northern and southern zones.
During that period millions of Jews were deported.
After the Vichy regime had been set, Pétain created many polices in order to help the Nazis for deportation. There were special polices for a part of population. For example, one for the Jews, another for the communists… Those polices were called the Militia, CGQJ, SSS and SPAC.
The most famous police was the Militia. It was created in 1943 to fight against the resistance fighters and also against the Jews. It had only 15 000 members but they terrified the population. Indeed, the militants could arrest anyone at anytime then torture them or deport them. They helped the Gestapo, the German police, and although they were not Nazis, the militants were harsh.
This service was created in May 1941. It mainly fought against the Freemasons but as its name wasn’t clear this service could fight against any kind of groupings. It was divided into 6 services among which the most important one was the research service. Altogether 989 Freemasons were deported and 540 were killed.
After those polices had arrested people in Ardeche, they took them to internment camps situated in Vals-les-Bains, near Aubenas, in Chabane and in Le Cheylard. Then there were sent by train to concentration camps.
