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.
