Franek, the Cadix operation in Vichy France still intrigues. Wiki has a page devoted to Polish Intelligence and briefly mentions that the Polish, French, and Spanish cryptologist work continued at Cadix following the Fall of France, but again fails to say what that work was! However the article generally gives some idea of the immense amount of work done in Europe and North Afica at the time, in particular in Algeria, paving the way for Operation Torch, in France reporting on U-Boat operations and of the Wehrmacht prior to and during Operation Overlord , and from Poland itself reporting the date of Barbarossa, the crimes at Auschwitz, and of V1 and V2 development. Altogether almost half of all reports received by British intelligence during WWII were of Polish origin.
The final paras sum up the debt owed but scarcely acknowledged and even denied :-
Historians' efforts to gain access to documentation of other Polish intelligence operations met with British stonewalling and with claims that the pertinent Polish archives had been destroyed by the British.
More recently, the British and Polish governments have begun jointly producing an accurate account of the Polish intelligence contribution to Britain's war effort. The key Anglo-Polish Historical Committee Report on the subject was published in July 2005. It was written by leading historians and experts who had been granted unprecedented access to British intelligence archives. The report concluded that 43 percent of all reports received by British secret services from continental Europe in 1939-45 had come from Polish sources

No doubt Cadix played a significant part in all this, but what part?
