SOE Operations in Sardinia and Corsica

Wartime Context

Following Italy’s entry into the Second World War, the Italian army occupied Corsica with the tacit agreement of the Vichy government, leading to the dissolution of French Brigades on the island [1]. While German presence was limited primarily to radar sites, the interior of the island was controlled by local patriots known as the Maqui, named after the dense shrubbery of the mountains [1]. In Sardinia, the strategic value of the island as a potential landing site or base for Allied forces made it a primary target for clandestine activity by the Combined Chiefs of Staff [2].

SOE and OSS Collaboration

The operations in the Mediterranean islands were characterized by close cooperation between the Special Operations Executive (SOE) and the Office of Strategic Services (OSS). In August 1943, the Combined Chiefs of Staff suggested that the OSS and SOE collaborate to establish conditions in Sardinia for an unopposed occupation or landing, utilizing “5th Column” activities and Italian assistance [2]. This collaboration served as a test for the effectiveness of these organizations in conducting similar future operations [2].

Operations in Corsica

In Corsica, the SOE focused on supporting the Maqui resistance. Small arms were smuggled to these patriots to bolster their presence, particularly around Ajaccio [1]. These efforts were complemented by OSS activities; for instance, an OSS agent codenamed “Tommy” organized a group known as “Pearl Harbor,” which was infiltrated in December 1942 and provided vital intelligence until the summer of 1943 [1]. Later, the OSS Operational Groups (OGs), working jointly with the French Bataillon du Choc, were tasked with attacking German installations to impede the evacuation of the German 90th Panzer Division along the east coast of Corsica [1].

Operations in Sardinia

The strategy for Sardinia involved inducing the Italian Army of Sardinia to turn against their German allies. General Donovan assigned Lt. Colonel Serge Obolensky to lead a mission to parachute into Sardinia to contact General Basso, the commanding officer of the Italian Army of Sardinia, and the headquarters of the King of Italy [4]. The objective was to persuade General Basso to attack German forces during their evacuation, specifically targeting routes leading north across the island and toward the straits of Bonifaccio toward Corsica [4]. The plan also sought approval to deploy OSS Operational Group units to harass and destroy enemy forces [4].

Logistics and Air Support

The success of these clandestine missions depended heavily on specialized air transport. In May 1943, the 1575 Special Duties Flight was formed at RAF Tempsford specifically to support the SOE [3]. This unit moved to North Africa in June 1943, where it commenced operations in Corsica, Sardinia, and Italy [3]. Renamed 624 Squadron in September 1943, the unit utilized Halifaxes and Stirlings to drop agents and supplies to resistance groups across the region [3].

Outcomes and Strategic Significance

The operations in Sardinia and Corsica demonstrated the viability of joint SOE-OSS efforts in the Mediterranean theater. By coordinating with local patriots and disgruntled Axis military commanders, the Allies were able to disrupt German evacuations and gather critical intelligence. The use of dedicated special duties flights like 624 Squadron ensured that resistance groups remained equipped and connected to Allied command, facilitating the eventual liberation of the islands.
