Frontstalag 133 was a temporary German prisoner of war camp during World War II located near Rennes, northern France. It operated from late 1940 to October 1943. It housed prisoners from French Colonial Forces.
About 200 of the captured British Commando troops from the St. Nazaire Raid were taken there, then sent on to other camps in Germany.
