I am assuming that the Germans would have a roster of the POWs at each Stalag they operated. You always hear of the Roll Call conducted daily or more frequently to make sure everyone was still there. Additionally I believe the Red Cross needed this to notify the POWs country that the individual was there. So does anyone know if there would be a location that keeps this information on Stalag 221 in Rennes France (i.e. Bundesarchiv, Red Cross) and how could I contact them? I have looked at several POW sites and they seem to have information on the Luft Stalags and other Stalags in Germany but little on other locations.
