Hi from Paris,
As I wrote recently on this forum, there is a lot of historical papers concerning Jews' fate around Nice during Shoah.
Unfortunately (nobody is perfect !) most of these documents are in French, as are archives in "Archives départementales des Alpes Maritimes", our administrative county of this area (fond 166).
I attach some pages on "Camp de Rivesaltes" where a lot of rounded up Jews had been sent.
Concerning Jewish Resistance, "Reseau Abadi" had been very active to protect and save children, as was "OSE" and "6eme EIF, Eclaireurs Isarelites de France".
You will find wikipedia pages about them.
Never forget the "Civil Resistance" of French population, 75% of Jewish persons present in France escaped deportation and were saved.
I hope you have some opportunity to read French and I attach some of these documents.
