This is a must read, that describes the french playing on all sides. The below is about their concentration camps- which spared no one.
As early as 1939, the existing camps were indiscriminately filled with German anti-Nazis (Communists, German Jews, etc.) or pro-Nazi Germans or also Nazi prisoners of war. Following the 1940 defeat, and the 10 July 1940 vote of full powers installing the Vichy regime, these camps were filled with Jews, first with foreign Jews, then indifferently with foreign and French Jews. The Vichy government would progressively hand them up to the Gestapo, and they would all transit by Drancy internment camp, the last stop before concentration camps in the Third Reich and in Eastern Europe and the extermination camps.
Beside Jews, Germans and Austrians were immediately rounded-up in camps, as well as Spanish refugees, who were later deported. 5,000 Spaniards thus died in Mauthausen concentration camp.[8] The French colonial soldiers were interned by the Germans on French territory, instead of being deported.[8]
