In World War II, the Alpes-Maritimes were occupied by the Italian Fourth Army November 11, 1942. The sympathy of the Italian authorities caused the area to become a safe haven for thousands of Jewish refugees. Jews were able to achieve a modicum of safety and legal residency under the Italian authorities, who relocated them to Saint-Martin-Vésubie. The sympathy of the Italian authorities was mainly due to the work of the Italian Jewish banker Angelo Donati, who was living in Nice and convinced them to protect the Jews from French and German persecution.
After the Italian Armistice in September 1943, and under direct threat from the German authorities, a thousand of Saint-Martin's Jews made the climb up the Old Salt Road mountain passes in the Gesso Valley and what they thought was the safety of Italy . All the remaining Jews in Saint-Martin were arrested and transported to Auschwitz.
The local gendarmerie commander, Maréchal des logis-chef Landry Mangon and his wife Adrienne took under protection a one year old Jewish child named Jean-Claude Dreymann and another officer Joseph Fougere and his wife Yvonne took the child's five-year-old sister Cecile and presented them as their children during the Gestapo's round-up of Jews and thereby saved their lives. For this noble act and the risks they took on their lives and their families to save Jews, the families of the officers were recognized as "Righteous among the Nations" at a ceremony conducted at the municipality on September 5, 2010.
