Besides the Hungarian Jews in Budapest, there were still a few Jewish communities in danger (who had not yet been deported).  Slovakia, which saw deportations from late August to September, and northern Italy, whose Jews got caught up as the Germans retreated up the boot to the north, were two.  The WRB requested the Pope intervene in both cases. Tiso was the ruler of Slovakia and a Catholic priest, so theoretically he would be susceptible to the Pope’s entreaties, and Italy was, well, Italy.  But apparently, the Vatican did not recognize the ruling parties in northern Italy and could not protest the deportations.
