Short Answer
Objective and Wartime Context
By late 1940, the British Air Ministry identified a critical threat from Kampfgruppe 100 (later Kampfgeschwader 100), a specialized German pathfinder wing of the Luftwaffe [2, 4]. Stationed at the Meucon airfield in Brittany, this unit spearheaded night raids on the United Kingdom by using specialized radio-navigation equipment (gonio) to drop incendiary bombs on targets, creating “triangles of fire” that guided subsequent waves of explosive bombers [4]. These tactics were responsible for some of the most severe bombardments of the Blitz, including attacks on Coventry and the London docks [4].
To neutralize this threat, the Air Ministry requested that the Special Operations Executive (SOE) destroy the unit by assassinating its pilots [1, 2]. The mission was designed to target the crews while they were billeted in the town of Vannes, near the Meucon airfield [1, 2].
Personnel and Organisations
Operation Savannah was a collaborative effort involving several Allied entities. While requested by the British Air Ministry and coordinated by the SOE, the operational force consisted of Free French paratroops [1, 2]. The mission was organized through the 2ème Bureau (the predecessor to the B.C.R.A., the central intelligence and action bureau of Free France), which was led by Captain André Dewavrin, known by the alias “Passy” [3].
The detachment was led by Capitaine Georges Bergé, commander of the 1st Air Infantry Company [2, 3]. In a letter dated 15 March 1941, Bergé informed General Charles de Gaulle of the departure of his five-man detachment, which had been specifically trained for this special mission [3].
Execution and Timeline
The mission took place during the night of 15 to 16 March 1941 [1, 3]. The five paratroops were transported by an RAF Armstrong Whitworth Whitley aeroplane [1, 2]. The insertion was a “blind drop,” occurring at midnight under the light of the moon [1, 2].
The landing was imprecise; the team touched down approximately five miles (8 km) off their intended target and eight miles (13 km) east of Vannes [1, 2]. Upon arrival, the team attempted to locate the German pilots to carry out the planned ambushes [1].
Outcome and Limitations
The mission failed to achieve its primary objective. Upon conducting reconnaissance the following day, Capitaine Bergé’s team discovered that their intelligence regarding the pilots’ movements was outdated [1, 2]. The Luftwaffe crews no longer commuted between the Meucon airfield and the town of Vannes by bus, as previously reported; instead, they traveled by private car as needed [2]. This change in routine made it nearly impossible to plan a successful ambush [2].
Despite the failure to neutralize the pathfinder pilots, the operation served as a significant early experiment in the insertion of special forces into occupied Europe. Bergé submitted a formal report on the mission on 9 April 1941 [3].
Strategic Significance
Operation Savannah is historically noted as the first insertion of SOE-trained Free French paratroops into German-occupied France [1, 2]. While tactically unsuccessful, it highlighted the extreme difficulty of blind drops and the volatility of human intelligence (HUMINT) in occupied territories. The mission underscored the necessity for more robust ground networks to provide real-time intelligence before the deployment of sabotage or assassination teams.
