I believe I've decided.
1st Arconian Legion
When Napoleon and his army entered Ancona, the Jewish community was living in a small ghetto. Napoleon, at that time, remarked that certain people were walking around with yellow bonnets and a yellow arm band with the "Star of David" on it. He asked one of his officers, what was the purpose of the yellow bonnet and the arm band. The officer replied that these were Jews who had to be identified in order that they return to the ghetto every evening. Napoleon immediately ordered that the arm bands and the yellow bonnets be removed and replaced them with the tricolor rosette. He closed the ghettos and gave instructions that the Jews could live wherever they wanted and they could practice their religion openly. The Jews of Ancona were overjoyed when they discovered that the first French soldiers who entered the ghetto were Jewish!
