Italian-occupied Corsica refers to the military (and administrative) occupation by the Kingdom of Italy of the island of Corsica during World War II. It lasted from November 1942 to September 1943.
After an initial period of increasing control over Corsica, Italian forces started losing territorial control to the local Resistance, and in the aftermath of the Italian capitulation to the Allies various units took different sides in the battle between newly landed German troops on one hand, and resistance fighters and Free French Forces on the other.
On 8 November 1942, the Allies landed in North Africa. In response, Nazi Germany formulated Operation Anton, as part of which Italy occupied the island of Corsica on November 11 (Italian operation codename: "Operazione C2"), and some parts of France up to the Rhone.
The Italian occupation of Corsica had been strongly promoted by the Italian irredentist movement during Italy's Fascist period. The occupation force initially included 30,000 Italian troops and gradually reached the size of nearly 85,000 soldiers. This was a huge occupation force relative to the size of the local population of 220,000.
The VII Army Corps of the Regio Esercito was able to occupy Corsica, which was still under the formal sovereignty of Vichy France, without a fight. Because of the initial lack of perceived partisan resistance and to avoid problems with Marshal Philippe Pétain, no Corsican units were formed under Italian control (except for a labour battalion in March 1943). The Corsican population initially showed some support for the Italians, partly as a consequence of irredentist propaganda.
