Jews: How Vichy Made It Worse from the March 6, 2014 issue

To the Editors:

Robert Paxton’s review of Jacques Semelin’s book Persecutions and Mutual Help in Occupied France [NYR, March 6] revealed some ignorance. “No detailed comparison of rates of rescue efforts seems to exist….” My book Accounting for Genocide: National Responses and Jewish Victimization During the Holocaust (1979) did compare efforts at rescue and the effect on Jewish survival, comparing within occupation zone, time of deportation, anti-Semitism prior to the war, and many other factors.
