Forces Françaises de l'Intérieur (EMFFI). It took many weeks for a full assessment of the contributions of SOE and the Jedburgh teams to the Allied landings in Normandy, but when it came it vindicated Gubbins' belief that carefully planned sabotage could cripple a modern army. General Eisenhower's staff at the Supreme Headquarters of the Allied Expeditionary Force said that the Jedburghs had "succeeded in imposing more or less serious delays on all the division moved to Normandy". This had prevented Hitler from striking back in the crucial opening hours of Operation Overlord. The most "outstanding example was the delay to the 2nd SS Panzer Division”, Eisenhower's staff said, and added a very personal endorsement, agreeing that the work carried out under Gubbins' leadership played a "very considerable part in our complete and final victory". Many agents were captured, killed in action, executed, or died in German concentration camps. More than one-third of 41 female agents of Section F did not survive the war; the death toll for more than 400 male agents was one-fourth and the toll of thousands of French people helping SOE agents and networks was about one-fifth.

Nevertheless, many members of SOE were Polish and the SOE and the Polish resistance cooperated extensively. SOE assisted the Polish government in exile with training facilities and logistical support for its 605 special forces operatives known as the Cichociemni, or "The Dark and Silent". Members of the unit, which was based in Audley End House, Essex, were rigorously trained before being parachuted into occupied Poland. Because of the distance involved in air travel to Poland, customised aircraft with extra fuel capacity were used in Polish operations such as Operation Wildhorn III. Sue Ryder chose the title Baroness Ryder of Warsaw in honour of these operations. Secret Intelligence Service member Krystyna Skarbek (nom de guerre Christine Granville) was a founder member of SOE and helped establish a cell of Polish spies in Central Europe. She ran several operations in Poland, Egypt, Hungary (with
