Operation Josephine B

Operation Josephine B (or Operation Josephine) was a military mission in June 1941 during the Second World War. The mission was organised jointly by the Free French and the British Special Operations Executive (SOE), together with the Royal Air Force for air drops. The operation was initially stalled by a lack of up-to-date information, but ultimately succeeded in its main objective, the destruction of an electrical transformer station in Pessac, near Bordeaux.

Six of the eight transformers were destroyed, resulting in the Italian submarine base at Bordeaux being hampered for weeks and a variety of other problems for the Italian and German occupiers. The operation was SOE's first success in occupied France and it considerably enhanced the organisation's standing.
