Italian occupation of France during World War II Italian - occupied France was an area of south - eastern France occupied by Fascist Italy in two stages during World War II . The occupation lasted from June 1940 until the Armistice between Italy and Allied armed forces on September 8 , 1943 , when Italian troops on French soil retreated under pressure from the Germans . Description . The Italian occupation of France occurred in two different periods during World War II : the first in June 1940 and the second in November 1942 . Characteristics . Overall , the Italian forces numbered about 700 , 000 troops in June 1940 . However , while they enjoyed a huge numerical superiority to the French , they had several deficiencies . The Italian armored regiments were from the 133 Armoured Division Littorio and included between 150 to 250 L3 / 35 tanks each . But these vehicles were often classified as " tankettes " and were little more than lightly armored machine - gun carriers not suited for modern warfare . Most Italian units had inadequate or obsolete artillery and lacked motor transport . Specific to this front , the Italians were not equipped for the cold Alpine environment , and faced the formidable fortifications of the Alpine Line ( called the " Little Maginot " ) . The Italian Army of occupation in southern France in November 1942 was made up of four infantry divisions with 136 , 000 soldiers and 6 , 000 officers , while in Corsica there were 66 , 000 soldiers with 3 , 000 officers . They faced no opposition from the Vichy Army . There was virtually no guerrilla war in France against the Italians until summer 1943 . Refuge . Many thousands of Jews moved to the Italian zone of occupation to escape Nazi persecution in Vichy France . Nearly 80 % of the remaining 300 , 000 French Jews took refuge there after November 1942 . The book Robert O . Paxton ' s " Vichy France , Old Guard , New Order " describes how the Italian zone acted as a refuge for Jews fleeing persecution in Vichy France during the occupation . The Italian Jewish banker Angelo Donati had an important role in convincing the Italian civil and military authorities to protect the Jews from the French persecution . In January 1943 the Italians refused to cooperate with the Nazis in rounding up the Jews living in the occupied zone of France under their control and in March prevented the Nazis from deporting Jews in their zone . German foreign minister Joachim von Ribbentrop complained to Mussolini that " Italian military circles . . . lack a proper understanding of the Jewish question . " However , when the Italians signed the armistice with the Allies , German troops invaded the former Italian zone ( September 8 , 1943 ) and initiated brutal raids . Alois Brunner , the SS official for Jewish affairs , was placed at the head of units formed to search out Jews . Within five months , 5 , 000 Jews were caught and deported . Mussolini had a Jewish mistress Margherita Sarfatti and refused to hand over Jews in Italian - occupied Europe to the Nazis . Bordeaux . The Italian Royal Navy ( " Regia Marina " ) established in August 1940 a submarine base at Bordeaux , outside Italian - occupied France . The base was code named BETASOM and , from it , thirty - two Italian submarines participated in the Battle of the Atlantic . These submarines sank 109 Allied merchant ships ( with 593 , 864 tons ) and 18 warships ( with 20 , 000 tons ) until September 1943 . Italian territorial claims . In addition to Nice / Nizza and Corsica , the Italians projected further territorial claims for the defeated France . In 1940 , The Italian Armistice Commission ( " Commissione Italiana d ' Armistizio con la Francia " , CIAF ) produced two detailed plans concerning the future of the occupied French territories . Plan ' A ' presented an Italian military occupation all the way to the river Rhone , in which France would maintain its territorial integrity except for Corsica and Nizza . Plan ' B ' encompassed the Italian annexation of the Alpes Maritimes ( including the Principality of Monaco ) and parts of Alpes - de - Haute - Provence , Hautes Alpes and Savoie . The territory would be administrated as the new Italian region of " Alpi Occidentali " with the town of Briançon ( Italian : " Brianzone " ) acting as the provincial capital .
