Charles Jocelyn Hambro
The Special Operations Executive (SOE) was a British World War II organisation. Following Cabinet approval, it was officially formed by Minister of Economic Warfare Hugh Dalton on 22 July 1940, to conduct espionage, sabotage and reconnaissance in occupied Europe against the Axis powers, and to aid local resistance movements.
It was initially also involved in the formation of the Auxiliary Units, a top secret "stay-behind" resistance organisation which would have been activated in the event of a German invasion of Britain.
Few people were aware of SOE's existence. To those who were part of it or liaised with it, it was sometimes referred to as "the Baker Street Irregulars", after the location of its London headquarters. It was also known as "Churchill's Secret Army" or the "Ministry of Ungentlemanly Warfare". For security purposes, various branches, and sometimes the organisation as a whole, were concealed behind names such as the "Joint Technical Board" or the "Inter-Service Research Bureau."
SOE operated in all countries or former countries occupied by or attacked by the Axis forces, except where demarcation lines were agreed with Britain's principal allies (the Soviet Union and the United States). It also made use of neutral territory on occasion, or made plans and preparations in case neutral countries were attacked by the Axis. The organisation directly employed or controlled just over 13,000 people, about 3,200 of whom were women. It is estimated that SOE supported or supplied about 1,000,000 operatives worldwide.
The organization was formed from the merger of three existing secret departments, which had been formed shortly before the outbreak of the Second World War. Immediately after Germany annexed Austria (the Anschluss) in March 1938, the Foreign Office created a propaganda organisation known as Department EH (after Electra House, its headquarters), run by Canadian newspaper magnate Sir Campbell Stuart. Later that month, the Secret Intelligence Service (SIS, also known as MI6) formed a section known as Section D, under Major Lawrence Grand, to investigate the use of sabotage, propaganda and other irregular means to weaken an enemy. In the autumn of the same year, the War Office set up a department, nominally for the purpose of research into guerrilla warfare and known initially as GS (R), headed by Major J. C. Holland. GS (R) was renamed MI R in early 1939.
These three departments worked with few resources until the outbreak of war. There was much overlap between their activities and Section D and EH duplicated much of each other's work. On the other hand, Section D and MI R shared information. Their heads were both officers of the Royal Engineers and knew each other. They agreed a rough division of their activities; MI R researched irregular operations which could be undertaken by regular uniformed troops, while Section D dealt with truly undercover work.
During the early months of the war, Section D was based at the Metropole Hotel in London. The Section attempted unsuccessfully to sabotage deliveries of vital strategic materials to Germany from neutral countries by mining the Iron Gate on the River Danube. MI R meanwhile produced pamphlets and technical handbooks for guerrilla leaders. MI R was also involved in the formation of the Independent Companies, autonomous units formed from within second-line Territorial Army divisions which were intended for sabotage and guerrilla operations behind enemy lines and which later developed into the British Commandos; and the Auxiliary Units, stay-behind resistance groups which would act in the event of an Axis invasion of Britain, as seemed possible in the early years of the war.
On 13 June 1940, at the instigation of newly-appointed Prime Minister Winston Churchill, Lord Hankey (who held the Cabinet post of Chancellor of the Duchy of Lancaster) persuaded Section D and MI R that their operations should be coordinated. On 1 July, a Cabinet level meeting arranged the formation of a single sabotage organisation. On 16 July, Hugh Dalton, the Minister of Economic Warfare, was appointed to take political responsibility for the new organisation, which was formally created on 22 July. Dalton used the Irish Republican Army (IRA) during the Irish war of Independence as a model for the organisation. Churchill ordered SOE to "set Europe ablaze". One department of MI R, MI R(C), which was involved in the development of weapons for irregular warfare, was not integrated into SOE but became an independent body codenamed MD1. (It was nicknamed "Churchill's Toyshop" from the Prime Minister's close interest in it and his enthusiastic support.) Majors Grand and Holland both returned to service in the regular army and Campbell Stuart left the organisation.
The Director of SOE was usually referred to by the initials "CD". The first Director to be appointed was Sir Frank Nelson, a former head of a trading firm in India, a back bench Conservative Member of Parliament and Consul in Basel, Switzerland.
Dalton was replaced as Minister of Economic Warfare by Lord Selborne in February 1942. Selborne in turn retired Nelson, who had suffered ill health as a result of his hard work, and appointed Sir Charles Hambro, head of the English banking firm Hambro's to replace him. Hambro had been a close friend of Churchill's before the war and had won the Military Cross in the First World War. Selborne also transferred Gladwyn Jebb, the senior civil servant who had run the Ministry's day-to-day dealings with SOE, back to the Foreign Office.
Selborne and Hambro cooperated closely until August 1943, when they fell out over the question of whether SOE should remain a separate body or coordinate its operations with those of the British Army in several theatres of war. Hambro felt that any loss of autonomy would cause a number of problems for SOE in the future. At the same time, Hambro was found to have failed to pass on vital information to Selborne. He was dismissed as Director, and became head of a raw materials purchasing commission in Washington, D.C., which was involved in the exchange of nuclear information.
As part of the subsequent closer ties between the Imperial General Staff and SOE (although SOE had no representation on the Chiefs of Staff Committee), Hambro's replacement as Director from September 1943 was the former Deputy Director, Major General Colin Gubbins. Gubbins had wide experience of commando and clandestine operations and had played a major part in MI R's early operations. He also put in practice many of the lessons he learned from the IRA during the Irish War of Independence.
The organization of SOE continually evolved and changed during the war. Initially, it consisted of three broad departments: SO1, which dealt with propaganda; SO2 (Operations); and SO3 (Research). SO3 was quickly overloaded with paperwork and was merged into SO2. In August 1941, following quarrels between the Ministry of Economic Warfare and the Ministry of Information over their relative responsibilities, SO1 was removed from SOE and became an independent organisation, the Political Warfare Executive.
Thereafter there was a single, broad "Operations" department which controlled the Sections operating into enemy and sometimes neutral territory, and the selection and training of agents. Sections were assigned to a single country. Some enemy-occupied countries had two or more sections assigned to deal with politically disparate resistance movements. (France had no less than six).
Four departments and some smaller groups were controlled by the Director of Scientific Research, (Professor Dudley Maurice Newitt), and were concerned with the development or acquisition and production of special equipment. A few other sections were involved with finance, security, economic research and administration, although SOE had no central registry or filing system. When Gubbins was appointed Director, he formalised some of the administrative practices which had grown in an ad hoc fashion and appointed an Establishment Officer to oversee the manpower and other requirements of the various departments.
The Director of SOE had either a Deputy from the Army, or (once Gubbins became Director) an army officer as Chief of Staff. The main controlling body of SOE was its Council, consisting of around fifteen heads of departments or sections. About half of the Council were from the armed forces (although some were specialists who were only commissioned after the outbreak of war), the rest were various civil servants, lawyers, or business or industrial experts.
Several subsidiary SOE headquarters and stations were set up to manage operations which were too distant for London to control directly. SOE's operations in the Middle East and Balkans were controlled from a headquarters in Cairo, which was notorious for poor security, infighting and conflicts with other agencies. It finally became known in April 1944 as Special Operations (Mediterranean), or SO(M). A subsidiary headquarters initially known as "Force 133" was later set up in Bari in Southern Italy under the Cairo headquarters to control operations in the Balkans and Northern Italy. There was also a station near Algiers, established in late 1942 and codenamed "Massingham", which operated into Southern France.
An SOE station, which was first called the India Mission, and was subsequently known as GS I(k) was set up in India late in 1940. It subsequently moved to Ceylon so as to be closer to the headquarters of the Allied South East Asia Command and became known as Force 136. A Singapore Mission was set up at the same time as the India Mission but was unable to overcome official opposition to its attempts to form resistance movements in Malaya before the Japanese overran Singapore. Force 136 took over its surviving staff and operations.
There was also a branch office in New York, formally titled British Security Coordination, and headed by the Canadian businessman Sir William Stephenson. This branch office, located at Room 3603, 630 Fifth Avenue, Rockefeller Center, coordinated the work of SOE, SIS and MI5 with the American F.B.I. and Office of Strategic Services.
SOE cooperated fairly well with Combined Operations Headquarters during the middle years of the war, usually on technical matters as SOE's equipment was readily adopted by commandos and other raiders. This support was lost when Vice Admiral Louis Mountbatten left Combined Operations, though by this time SOE had its own transport and had no need to rely on Combined Operations for resources. On the other hand, the Admiralty objected to SOE developing its own underwater vessels, and the duplication of effort this involved. The Royal Air Force, and in particular RAF Bomber Command under "Bomber" Harris also objected to aircraft being allocated to SOE.
SOE's relationships with the Foreign Office were difficult on several occasions, as various governments in exile protested at operations taking place without their knowledge or approval, which resulted in Axis reprisals against civilian populations. SOE nevertheless generally adhered to the rule, "No bangs without Foreign Office approval." There was also tension between SOE and SIS, which the Foreign Office controlled. Where SIS preferred placid conditions in which it could gather intelligence and work through influential persons or authorities, S.O.E. was intended to create unrest and turbulence, and often backed anti-establishment organisations, such as the Communists, in several countries. At one stage, SIS actively hindered SOE's attempts to infiltrate agents into enemy-occupied France.
Towards the end of the war, as Allied forces began to liberate territories occupied by the Axis and in which SOE had established resistance forces, SOE also liaised with and to some extent came under the control of the Allied theatre commands. Relationships with Supreme Headquarters Allied Expeditionary Force in north-west Europe (whose commander was General Dwight D. Eisenhower) and South East Asia Command (whose commander was Admiral Louis Mountbatten, already well known to SOE) were generally excellent.
Towards the end of the war, Lord Selborne advocated keeping SOE, or a similar body, in being. He proposed that the organisation could be useful against "the Russian menace" and "the smouldering volcanoes of the Middle East", and that it would report to the Ministry of Defence. The Foreign Secretary, Anthony Eden, insisted that his ministry, already responsible for the SIS, should control SOE or its successors. Selborne retorted that "To have SOE run by the Foreign Office would be like inviting an abbess to supervise a brothel." Churchill took no decision, and after he lost the general election in 1945, the matter was dealt with by the Labour Prime Minister, Clement Attlee.
Selborne told Attlee that SOE still possessed a worldwide network of clandestine radio networks and sympathisers. Attlee replied that he had no wish to own a British Comintern, and closed Selborne's network down at 48 hours' notice. SOE was dissolved officially on 15 January 1946. Most of its personnel reverted to their peacetime occupations (or regular service in the armed forces), but 280 personnel were taken into the "Special Operations Branch" of MI6. Some of these had served as agents in the field, but MI6 was most interested in SOE's training and research staff. Sir Stewart Menzies, the head of MI6 (who was generally known simply as "C") soon decided that a separate branch was unsound, and merged it into the general body of MI6.
SOE maintained a large number of training, research and development or administrative centres. It was a joke that "SOE" stood for "Stately 'omes of England", after the large number of country houses and estates it requisitioned and used.
After working from temporary offices in Central London, the headquarters of SOE was moved on 31 October 1940 into 64 Baker Street (hence the nickname "the Baker Street Irregulars"). Ultimately, SOE occupied much of the western side of Baker Street.
The main weapons and devices research establishments were The Firs, the home of MD1 near Aylesbury in Buckinghamshire, and Station IX at The Frythe, a former hotel outside Welwyn Garden City where, under the cover name of ISRB (Inter Services Research Bureau), SOE developed radios, weapons, explosive devices and booby traps. Station XII at Aston House near Stevenage in Hertfordshire originally conducted research and development but later became a production, storage and distribution centre for devices already developed.
Station XV, at the Thatched Barn near Borehamwood, was devoted to camouflage, which usually meant equipping agents with authentic local clothing and personal effects. Various sub-stations in London, and Station XIV near Roydon in Essex which specialised in forgery of identity papers, ration books and so on, were also involved in this task. Station XV and other camouflage sections also devised methods of hiding weapons, explosives or radios in innocuous-seeming items.
The initial training centres of the SOE were at country houses such as Wanborough Manor, Guildford. Agents destined to serve in the field underwent commando training at Arisaig in Scotland, where they were taught armed and unarmed combat skills by William E. Fairbairn and Eric A. Sykes, former Inspectors in the Shanghai Municipal Police. They then attended courses in security and "tradecraft" at Group B schools around Beaulieu in Hampshire. Finally, they received specialist training in skills such as demolition techniques or Morse code telegraphy at various country houses in England and parachute training (if necessary) by STS 51 and 51a situated near Altrincham, Cheshire with the assistance of No.1 Parachute Training School RAF, at RAF Ringway (which later became Manchester Airport).
A variety of people from all classes and pre-war occupations served SOE in the field. The backgrounds of agents in F Section, for example, ranged from Indian royalty (Noor Inayat Khan) to working class, with some even reputedly from the criminal underworld.
In most cases, the primary quality required of an agent was a deep knowledge of the country in which he or she was to operate, and especially its language, if the agent was to pass as a native of the country. Dual nationality was often a prized attribute. This was particularly so of France. In other cases, especially in the Balkans, a lesser degree of fluency was required as the resistance groups concerned were already in open rebellion and a clandestine existence was unnecessary. A flair for diplomacy combined with a taste for rough soldiering was more necessary. Some regular army officers proved adept as envoys, although others (such as the former diplomat Fitzroy Maclean or the classicist Christopher Woodhouse) were commissioned only during wartime.
Exiled or escaped members of the armed forces of some occupied countries were obvious sources of agents. This was particularly true of Norway and the Netherlands. In other cases (such as Frenchmen owing loyalty to Charles de Gaulle and especially the Poles), the agents' first loyalty was to their leaders or governments in exile, and they treated SOE only as a means to an end. This could occasionally lead to mistrust and strained relations in Britain.
The organisation was prepared to ignore almost any contemporary social convention in its fight against the Axis. It employed known homosexuals, people with criminal records (some of whom taught skills such as lock-picking) or bad conduct records in the armed forces, Communists and anti-British nationalists. Although some of these might have been considered a security risk, there is practically no known case of an SOE agent wholeheartedly going over to the enemy. However, there were cases such as that of Henri Déricourt, in which the conduct of agents was questionable but it was impossible to establish whether they were acting under secret orders from SOE or MI6.
Most of the resistance networks which SOE formed or liaised with were controlled by radio directly from Britain or one of SOE's subsidiary headquarters. The main transmitting and receiving stations in Britain were at Grendon Underwood and Poundon, both in Buckinghamshire (and near the SIS-controlled Bletchley Park; the location and topography were suitable for all three sites). All resistance circuits contained at least one wireless operator, and all drops or landings were arranged by radio, except for early exploratory missions sent "blind" into enemy-occupied territory.
This made SOE highly dependent upon the security of radio transmissions. There were three factors involved in this: the physical qualities and capabilities of the radio sets, the security of the transmission procedures and the provision of proper ciphers.
SOE's first radios were supplied by SIS. They were large, clumsy and required large amounts of power. SOE acquired a few, much more suitable, sets from the Poles in exile, but eventually designed and manufactured their own, such as the Paraset. Some of these, together with their batteries, weighed only 9 pounds (4.1 kg), and could fit into a small attache case, although larger sets were required to work over ranges greater than about 500 miles (800 km).
Operating procedures were insecure at first. Operators were forced to transmit verbose messages on fixed frequencies and at fixed times and intervals. This allowed German direction finding teams time to triangulate their positions. After several operators were captured or killed, procedures were made more flexible and secure. The SOE wireless operators were also known as "The Pianists".
As with their first radio sets, SOE's first ciphers were inherited from SIS. Leo Marks, SOE's chief cryptographer, was responsible for the development of better codes to replace the insecure poem codes. Eventually, SOE settled on single use ciphers, printed on silk. Unlike paper, which would be given away by rustling, silk would not be detected by a casual search if it was concealed in the lining of clothing.
British Broadcasting Corporation 
The BBC also played its part in communications with agents or groups in the field. During the war, it broadcast to almost all Axis-occupied countries, and was avidly listened to, even at risk of arrest. The BBC included various "personal messages" in its broadcasts, which could include lines of poetry or apparently nonsensical items. They could be used to announce the safe arrival of an agent or message in London for example, or could be instructions to carry out operations on a given date.
Other methods 
In the field, agents could sometimes make use of the postal services, though these were slow, not always reliable and letters were almost certain to be opened and read by the Axis security services. In training, agents were taught to use a variety of easily-available substances to make invisible ink, though most of these could be detected by a cursory examination, or to hide coded messages in apparently innocent letters. The telephone services were even more certain to be intercepted and listened to by the enemy, and could be used only with great care.
The most secure method of communication in the field was by courier. In the earlier part of the war, most women sent as agents in the field were employed as couriers, on the assumption that they would be less likely to be suspected of illicit activities.
Although SOE used some silenced assassination weapons such as the De Lisle carbine and the Welrod (specifically developed for SOE at Station IX), it took the view that weapons issued to resisters should not require extensive training in their use, or need careful maintenance. The crude and cheap Sten was a favourite. For issue to large forces such as the Yugoslav Partisans, SOE used captured German or Italian weapons. These were available in large quantities after the Tunisian and Sicilian campaigns and the surrender of Italy, and the partisans could acquire ammunition for these weapons (and the Sten) from enemy sources.
SOE also adhered to the principle that resistance fighters would be handicapped rather than helped by heavy equipment such as mortars or anti-tank guns. These were awkward to transport, almost impossible to conceal and required skilled and highly trained operators. Later in the war however, when resistance groups staged open rebellions against enemy occupation, some heavy weapons were dispatched, for example to the Maquis du Vercors.
Most SOE agents received training on captured enemy weapons before being sent into enemy-occupied territory. Ordinary SOE agents were also armed with handguns acquired abroad, such as, from 1941, a variety of US pistols, and a large quantity of the Spanish Llama .38 ACP in 1944. Such was SOE's demand for weapons, a consignment of 8,000 Ballester-Molina .45 calibre weapons was purchased from Argentina, apparently with the mediation of USA.
SOE agents were issued with the Sykes-Fairbairn fighting knife also issued to Commandos. For specialised operations or use in extreme circumstances, SOE issued small fighting knives which could be concealed in the heel of a hard leather shoe or behind a coat lapel. Given the likely fate of agents captured by the Gestapo, SOE also disguised suicide pills as coat buttons.
SOE developed a wide range of explosive devices for sabotage, such as limpet mines, shaped charges and time fuses. These were also used by commando units. SOE pioneered the use of plastic explosive. (The term "plastique" comes from plastic explosive packaged by SOE and originally destined for France but taken to the United States instead.) Plastic explosive could be shaped and cut to perform almost any demolition task. It was also inert and required a powerful detonator to cause it to explode, and was therefore safe to transport and store. It was used in everything from car bombs, to exploding rats designed to destroy coal-fired boilers.
Other, more subtle sabotage methods included lubricants laced with grinding materials, incendiaries disguised as innocuous objects, explosive material concealed in coal piles to destroy locomotives, and land mines disguised as cow or elephant dung. On the other hand, some sabotage methods were extremely simple but effective, such as using sledgehammers to crack cast-iron mountings for machinery.
Station IX developed several miniature submersible craft. The Welman submarine and Sleeping Beauty were offensive weapons, intended to place explosive charges on or adjacent to enemy vessels at anchor. The Welman was used once or twice in action, but without success. The Welfreighter was intended to deliver stores to beaches or inlets, but it too was unsuccessful.
A sea trials unit was set up in West Wales at Goodwick, by Fishguard (station IXa) where these craft were tested. In late 1944 craft were dispatched to Australia to the Allied Intelligence Bureau (SRD), for tropical testing.
SOE also revived some medieval devices, such as the caltrop, which could be used to burst the tyres of vehicles or injure foot soldiers, and crossbows powered by multiple rubber bands to shoot incendiary bolts. There were two types, known as "Big Joe" and "Li'l Joe" respectively. They had tubular alloy skeleton stocks and were designed to be collapsible for ease of concealment.
Some of the other more imaginative devices invented by SOE included exploding pens with enough explosive power to blast a hole in the bearer's body, or guns concealed in tobacco pipes, though there is no record of any of these being used.
The continent of Europe was largely closed to normal travel. Although it was possible in some cases to cross frontiers from neutral countries such as Spain or Sweden, this was slow and there were issues over violating these countries' neutrality. SOE had to rely largely on its own air or sea transport for movement of people, arms and equipment.
SOE was engaged in disputes with the RAF from its early days. In January 1941, an intended ambush against the aircrew of a German "pathfinder" air group near Vannes in Brittany was thwarted when Air Vice Marshal Charles Portal, the Chief of the Air Staff, objected on moral grounds to parachuting what he regarded as assassins.
Although Portal's objections were later overcome, Air Marshal Harris ("Bomber Harris"), the Commander-in-Chief of Bomber Command, resented the diversion of bombers to SOE purposes (or indeed any purposes other than the offensive against German cities). He too was overruled and by April 1942, SOE had the services of 138 and 161 squadrons at RAF Tempsford.
The aircraft used by SOE included the Westland Lysander, which could carry up to three passengers and two panniers loaded with stores, and had an effective range of 700 miles (1,100 km). It could use rough landing strips only 400 yards (370 m) in length, or even less. Lysanders were used to transport 101 agents to and 128 agents from Nazi-occupied Europe. The Lockheed Hudson had a range 200 miles (320 km) greater and could carry more passengers (ten or more), but required landing strips twice as long as those needed for the Lysander.
To deliver agents and stores by parachute, SOE could use several aircraft originally designed as bombers: the Armstrong Whitworth Whitley until November 1942, the Handley Page Halifax and the Short Stirling. The Stirling could carry a particularly large load, but only the Halifax had the range to reach dropping zones in eastern Poland (and even then, only from bases in Southern Italy). Later in the war, SOE also used the American-designed C47, which was often landed at airfields in territory held by partisans in the Balkans.
Stores were usually parachuted in cylindrical containers. The "C" type was 69 inches (180 cm) long and when fully loaded could weigh up to 224 pounds (102 kg). The "H" type was the same size overall but could be broken down into five smaller sections. This made it easier to carry and conceal but made it impossible to carry long loads such as rifles. Some inert stores such as boots and blankets were "free-dropped" i.e. simply thrown out of the aircraft bundled together without a parachute, often to the hazard of any receiving committee on the ground.
Locating and homing equipment 
Some devices used by SOE were designed specifically to guide aircraft to landing strips and dropping zones. Such sites could be marked by an agent on the ground with bonfires or bicycle lamps, but this required good visibility, as the pilot of an aircraft had not only to spot the ground signals, but also to navigate by visible landmarks to correct dead reckoning. Many landings or drops were thwarted by bad weather. To overcome these problems, SOE and Allied airborne forces used the Rebecca/Eureka transponding radar, which enabled an aircraft to home in on a point on the ground even in thick weather. It was however difficult to carry or conceal. SOE also developed the S-Phone, which allowed a pilot or radio operator aboard an aircraft to communicate by voice with the "reception committee". Sound quality was good enough for voices to be recognisable, so that a mission could be aborted if there was any doubt of an agent's identity.
SOE also experienced difficulties with the Royal Navy, who were usually unwilling to allow SOE to use its submarines or motor torpedo boats to deliver agents or equipment. Submarines were regarded as too valuable to risk within range of enemy coastal defences, and MTBs were in any case often too noisy and conspicuous for clandestine landings. However, SOE often used clandestine craft such as local fishing boats or caiques and eventually ran quite large fleets of these, from the Helford estuary, Algiers, the Shetland Islands (a service termed the Shetland Bus), Ceylon etc.
SOE's operations were usually mounted in order to feel out resistance groups willing to work with the Allies in preparation for invasion. In France, personnel were directed by two London-based country sections. F Section was under British control, while RF Section was linked to General de Gaulle's Free French government in exile. Most native French agents served in RF. There were also two smaller sections: EU/P Section, which dealt with the Polish community in France, and the DF Section which was responsible for establishing escape routes. During the latter part of 1942 another section known as AMF was established in Algiers, to operate into Southern France.
On 5 May 1941, Georges Bégué (1911–1993) became the first SOE agent dropped into German occupied France. He then set up radio communications and met the next agents parachuted into France. Between Bégué's first drop in May 1941 and August 1944, more than four hundred F Section agents were sent into occupied France. They served in a variety of functions including arms and sabotage instructors, couriers, circuit organisers, liaison officers and radio operators. RF sent about the same number; AMF sent 600 (although not all of these belonged to SOE). EU/P and DF sent a few dozen agents each.
SOE included a number of women (who were often commissioned into women's branches of the armed forces such as the First Aid Nursing Yeomanry). F Section alone sent 39 female agents into the field, of whom 13 did not return. The Valençay SOE Memorial was unveiled at Valençay in the Indre département of France on 6 May 1991, marking the fiftieth anniversary of the despatch of F Section's first agent to France. The memorial's roll of honour lists the names of the 91 men and 13 women members of the SOE who gave their lives for France's freedom.
To support the Allied invasion of France on D Day in June 1944, three-man parties were dropped into various parts of France as part of Operation Jedburgh, to coordinate widespread overt (as opposed to clandestine) acts of resistance. A total of 100 men were eventually dropped, together with 6,000 tons of military stores (4,000 tons had been dropped during the years before D-Day.) At the same time, all the various sections operating in France (except EU/P) were nominally placed under a London-based HQ titled État-major des Forces Françaises de l'Intérieur (EMFFI).
SOE did not need to instigate Polish resistance, because unlike the Vichy French the Poles overwhelmingly refused to collaborate with the Nazis. Early in the war the Poles established the Polish Home Army, led by a clandestine resistance government known as the Polish Secret State. Nevertheless, there were many Polish members of SOE and much cooperation between the SOE and the Polish resistance.
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 Andrzej Kowerski) and France, often using the staunchly anti-Nazi Polish expatriate community as a secure international network. Non-official cover agents Elzbieta Zawacka and Jan Nowak-Jezioranski perfected the Gibraltar courier route out of occupied Europe. Maciej Kalenkiewicz was parachuted into occupied Poland, only to be killed by the Soviets. A Polish agent was integral to SOE's Operation Foxley, the plan to assassinate Hitler.
Thanks to cooperation between SOE and the Polish Home Army, the Poles were able to deliver the first Allied intelligence on the Holocaust to London in June 1942. Witold Pilecki of the Polish Home Army designed a joint operation with SOE to liberate Auschwitz, but the British rejected it as infeasible. Joint Anglo-Polish operations provided London with vital intelligence on the V-2 rocket, German troops movements on the Eastern Front, and the Soviet repressions of Polish citizens.
RAF 'Special Duties Flights' were sent to Poland to assist the Warsaw Uprising against the Nazis. The rebellion was defeated with a loss of 200,000 casualties (mostly German executions of Polish civilians) after the nearby Red Army refused military assistance to the Polish Home Army. RAF Special Duties Flights were refused landing rights at Soviet-held airfields near Warsaw, even when requiring emergency landings after battle damage. These flights were also attacked by Soviet fighters, despite the U.S.S.R.'s officially Allied status.
Due to the dangers and lack of friendly population few operations were conducted in Germany itself. The German and Austrian section of SOE was run by Lieutenant Colonel Ronald Thornley for most of the war, and was mainly involved with black propaganda and administrative sabotage in collaboration with the German section of the Political Warfare Executive. After D-Day, the section was re-organised and enlarged with Major General Gerald Templer heading the Directorate, with Thornley as his deputy.
Several major operations were planned, including Operation Foxley, a plan to assassinate Hitler, and Operation Periwig, an ingenious plan to simulate the existence of a large-scale anti-Nazi resistance movement within Germany. Foxley was never carried out but Periwig went ahead despite restrictions placed on it by SIS and SHAEF. Several German prisoners of war were trained as agents, briefed to make contact with the anti-Nazi resistance and to conduct sabotage. They were then parachuted into Germany in the hope that they would either hand themselves in to the Gestapo or be captured by them, and reveal their supposed mission. Fake coded wireless transmissions were broadcast to Germany and various pieces of agent paraphernalia such as code books and wireless receivers were allowed to fall into the hands of the German authorities.
The Netherlands 
Section N of SOE ran operations in the Netherlands. They committed some of SOE's worst blunders in security, which allowed the Germans to capture many agents and much sabotage material, in what the Germans called the "Englandspiel". SOE apparently ignored the absence of security checks in radio transmissions, and other warnings from their chief cryptographer, Leo Marks, that the Germans were running the supposed resistance networks.
Eventually, two captured agents escaped to Switzerland in August 1943. There, the Netherlands Embassy sent messages over their controlled sets to England that SOE Netherlands was compromised. SOE was at last more wary.
SOE partly recovered from this disaster to set up new networks, which continued to operate until the Netherlands were liberated at the end of the war.
A total of 50 agents were captured, compromised by other agents or captives. Most did not survive the war.
Section T established some effective networks in Belgium, in part orchestrated by fashion designer Hardy Amies, who rose to the rank of Lieutenant Colonel. Amies adapted names of fashion accessories for use as code words, while managing some of the most murderous and ruthless agents in the field. In the aftermath of the Battle of Normandy, British armoured forces liberated the country in less than a week, giving the resistance little time to stage an uprising. They did assist British forces to bypass German rearguards, and this allowed the Allies to capture the vital docks at Antwerp intact (although a protracted and bloody Battle of the Scheldt was later fought to clear the Scheldt estuary before the Allies could use the port).
After Brussels was liberated, Amies outraged his superiors by setting up a Vogue photo-shoot in Belgium. In 1946, he was Knighted in Belgium for his service with SOE, being a Named Officier de l'Ordre de la Couronne.
As both an enemy country, and supposedly a monolithic fascist state with no organised opposition which SOE could use, SOE made little effort in Italy before mid-1943, when Mussolini's government collapsed and Allied forces already occupied Sicily. In April 1941, in a mission codenamed "Yak", Peter Fleming attempted to recruit agents from among the many thousands of Italian prisoners of war captured in the Western Desert Campaign. He met with no response. Attempts to search among Italian immigrants in the United States, Britain and Canada for agents to be sent to Italy had similarly poor results.
During the first three years of war, the most important "episode" of the collaboration between SOE and Italian antifascism was a project of an antifascist uprising in Sardinia, which the SOE supported at some stage but did not receive approval from the Foreign Office.
In the aftermath of the Italian collapse, SOE (in Italy renamed N. 1 Special Force) helped build a large resistance organisation in the cities of Northern Italy, and in the Alps. Italian partisans harassed German forces in Italy throughout the autumn and winter of 1944, and in the Spring 1945 offensive in Italy they captured Genoa and other cities unaided by Allied forces. SOE helped the Italian Resistance send British missions to the partisan formations and supply war material to the bands of patriots, a supply made without political prejudices, and which also helped the Communist formations (Brigate Garibaldi).
Late in 1943, SOE established a base at Bari in Southern Italy, from which they operated their networks and agents in the Balkans. This organisation had the codename "Force 133". This later became "Force 266", reserving 133 for operations run from Cairo rather than the heel of Italy. Flights from Brindisi were run to the Balkans and Poland, particularly once control had been wrested from SOE's Cairo headquarters and was exercised directly by Gubbins. SOE established a new packing station for the parachute containers close to Brindisi Air base, along the lines of those created at Saffron Walden. This was ME 54, a factory employing hundreds, the American (OSS) side of which was known as "Paradise Camp".
In the aftermath of the German invasion in 1941, the Kingdom of Yugoslavia fragmented. In Croatia, there was a substantial pro-Axis movement, the Ustaše. In Croatia as well as the remainder of Yugoslavia, two resistance movements formed; the royalist Chetniks under Draža Mihailović, and the Communist Partisans under Josip Broz Tito.
Mihailović was the first to attempt to contact the Allies, and SOE despatched a party on 20 September 1941 under Major "Marko" Hudson. Hudson also encountered Tito's forces. Through the royalist government in exile, SOE at first supported the Chetniks. Eventually, however, due to reports that the Chetniks were less effective and even collaborating with German and Italian forces on occasion, British support was redirected to the Partisans, even before the Tehran Conference in 1943.
Although relations were often touchy throughout the war, it can be argued that SOE's unstinting support was a factor in Yugoslavia's maintaining a neutral stance during the Cold War. However, accounts vary dramatically between all historical works on the "Chetnik controversy".
SOE was unable to establish links or contacts in Hungary before the regime of Miklós Horthy aligned itself with the Axis Powers. Distance and lack of such contacts prevented any effort being made by SOE until the Hungarians themselves dispatched a diplomat (László Veress) in a clandestine attempt to contact the Western Allies. SOE facilitated his return, with some radio sets. Before the Allied governments could agree terms, Hungary was placed under German military occupation and Veress was forced to flee the country.
Two missions subsequently dropped "blind" i.e. without prior arrangement for a reception party, failed. So too did an attempt by Basil Davidson to incite a partisan movement in Hungary, after he made his way there from northeastern Yugoslavia.
Greece was overrun by the Axis after a desperate defence lasting several months. In the aftermath, SIS and another intelligence organisation, SIME, discouraged attempts at sabotage or resistance as this might imperil relations with Turkey, although SOE maintained contacts with resistance groups in Crete. When an agent, "Odysseus", a former tobacco-smuggler, attempted to contact potential resistance groups in Greece, he reported that no group was prepared to cooperate with the monarchist government in exile in Cairo.
In late 1942, at the army's instigation, SOE mounted its first operation, codenamed Operation Harling, into Greece in an attempt to disrupt the railway which was being used to move materials to the German Panzer Army Africa. A party under Colonel (later Brigadier) Eddie Myers, assisted by Christopher Woodhouse, was parachuted into Greece and discovered two guerrilla groups operating in the mountains: the pro-Communist ELAS and the republican EDES. On 25 November 1942, Myers's party blew up one of the spans of the railway viaduct at Gorgopotamos, supported by 150 Greek partisans from these two organisations who engaged Italians guarding the viaduct. This cut the railway linking Thessaloniki with Athens and Piraeus.
Relations between the resistance groups and the British soured. When the British needed once again to disrupt the railway across Greece as part of the deception operations preceding Operation Husky, the Allied invasion of Sicily, the resistance groups refused to take part, rightly fearing German reprisals against civilians. Instead, a six-man commando party from the British and New Zealand armies carried out the destruction of the Asopos viaduct on 21 June 1943.
EDES received most aid from SOE, but ELAS secured many weapons when Italy collapsed and Italian military forces in Greece dissolved. ELAS and EDES fought a vicious civil war in 1943 until SOE brokered an uneasy armistice (the Plaka agreement).
A lesser known, but important function of the SOE in Greece was to inform the Cairo headquarters of the movement of the German military aircraft that were serviced and repaired at the two former Greek military aircraft facilities in and around Athens.
Eventually, the British Army occupied Athens and Piraeus in the aftermath of the German withdrawal, and fought a street-by-street battle to drive ELAS from these cities and impose an interim government under Archbishop Damaskinos. SOE's last act was to evacuate several hundred disarmed EDES fighters to Corfu, preventing their massacre by ELAS.
In Crete there were several resistance groups and Allied stay-behind parties after the Germans occupied the island in the Battle of Crete. SOE's operations on Crete involved figures such as Patrick Leigh Fermor, John Lewis, Tom Dunbabin, Sandy Rendel, John Houseman, Xan Fielding and Bill Stanley Moss. Some of the most famous moments included the abduction of General Heinrich Kreipe led by Leigh Fermor and Moss, and the sabotage of Damasta led by Moss.
Albania had been under Italian influence since 1923, and was occupied by the Italian Army in 1939. In 1943, a small liaison party entered Albania from northwestern Greece. SOE agents who entered Albania then or later included Julian Amery, Anthony Quayle, David Smiley and Neil "Billy" McLean. They discovered another internecine war between the Communist partisans under Enver Hoxha, and the republican Balli Kombëtar. As the latter had collaborated with the Italian occupiers, Hoxha gained Allied support.
SOE's envoy to Albania, Brigadier Edmund "Trotsky" Davies, was captured by the Germans early in 1944. Some SOE officers warned that Hoxha's aim was primacy after the war, rather than fighting Germans. They were ignored, but Albania was never a major factor in the effort against the Germans.
SOE sent many missions into the Czech areas of the so-called Protectorate of Bohemia and Moravia, and later into Slovakia. The most famous mission was Operation Anthropoid, the assassination of SS-Obergruppenführer Reinhard Heydrich in Prague. From 1942 to 1943 the Czechoslovaks had their own Special Training School (STS) at Chicheley Hall in Buckinghamshire. In 1944, SOE sent men to support the Slovak National Uprising.
In March 1941 a group performing commando raids in Norway, Norwegian Independent Company 1 (NOR.I.C.1) was organised under leadership of Captain Martin Linge. Their initial raid in 1941 was Operation Archery, the best known raid was probably the Norwegian heavy water sabotage. Communication lines with London were gradually improved so that by 1945, 64 radio operators were spread throughout Norway.
Most of the actions conducted by the Danish resistance were railway sabotage to hinder German troop and material movements from and to Norway. However, there were examples of sabotage on a much larger scale especially by BOPA. In all over 1,000 operations were conducted from 1942 and onwards.
In October 1943 the Danish resistance also saved nearly all of the Danish Jews from certain death in German concentration camps. This was a massive overnight operation and is to this day recognised among Jews as one of the most significant displays of public defiance against the Germans.
The Danish resistance assisted SOE in its activities in neutral Sweden. For example, SOE was able to obtain several shiploads of vital ball-bearings which had been interned in Swedish ports. The Danes also pioneered several secure communications methods; for example, a burst transmitter/receiver which transcribed Morse code onto a paper tape faster than a human operator could handle.
There are a series of Historic Notes written by David Lampe in his "The Danish Resistance" also called "The Savage Canary".
In 1943 an SOE delegation was parachuted into Romania to instigate resistance against the Nazi occupation at "any cost" (Operation Autonomous). The delegation, including Colonel Gardyne de Chastelain, Captain Silviu Meţianu and Ivor Porter, was captured by the Romanian Gendarmerie and held until the night of King Michael's Coup on 23 August 1944.
Other operations in Europe 
Through cooperation with the Special Operations Executive and the British intelligence service, a group of Jewish volunteers from Palestine were sent on missions to several countries in Nazi-occupied Europe from 1943 to 1945.
Abyssinia was the scene of some of SOE's earliest and most successful efforts. SOE organised a force of Ethiopian irregulars under Orde Charles Wingate in support of the exiled Emperor Haile Selassie. This force (named Gideon Force by Wingate) caused heavy casualties to the Italian occupation forces, and contributed to the successful British campaign there. Wingate was to use his experience to create the Chindits in Burma.
Southeast Asia 
As early as 1940, SOE was preparing plans for operations in Southeast Asia. As in Europe, after initial Allied military disasters, SOE built up indigenous resistance organisations and guerrilla armies in enemy (Japanese) occupied territory. SOE also launched "Operation Remorse" (1944–45), which was ultimately aimed at protecting the economic and political status of Hong Kong. Force 136 engaged in covert trading of goods and currencies in China. Its agents proved remarkably successful, raising £77m through their activities, which were used to provide assistance for Allied prisoners of war and, more controversially, to buy influence locally in order to facilitate a smooth return to pre-war conditions.
Later analysis and commentaries 
The mode of warfare encouraged and promoted by SOE is considered by several modern commentators to have established the modern model that many alleged terrorist organisations emulate, pioneering most of the tactics, techniques and technologies that are the mainstays of terrorism as it is commonly known today.
In popular culture 
- Now It Can Be Told (aka School for Danger) (1946)
- Filming began in 1944 and starred real-life SOE agents Captain Harry Rée and Jacqueline Nearne. The film tells the story of the training of agents for SOE and their adventures in France. The training sequences were filmed using the SOE equipment at the training schools at Traigh and Garramor (South Morar) and at Ringway.
- The Fight over the Heavy Water (1948)
- A French/Norwegian black and white docu-film titled "La Bataille de l'eau lourde"/"Kampen om tungtvannet" (trans. "The Fight Over the Heavy Water"), featured some of the ‘original cast’, so to speak. Joachim Rønneberg has stated; "The Fight over Heavy Water was an honest attempt to describe history. On the other hand 'Heroes of Telemark' had little to do with reality."
- Odette (1950)
- Based on the book by Jerrard Tickell about Odette Sansom, starring Anna Neagle and Trevor Howard. The film includes an interview with Maurice Buckmaster, head of F-Section, SOE.
- Ill Met by Moonlight (film) (1957)
- The Powell and Pressburger film, (released as Night Ambush in the States), based on the book by W. Stanley Moss, starring Dirk Bogarde and Marius Goring. It dramatises the true story of the capture of a German general by Patrick Leigh Fermor and W. Stanley Moss.
- Bridge on the River Kwai (1957) is a well-known classic British-made war-drama set in Burma during World War II, during the construction of the Siam–Burma railway through virgin jungle and endless hills and gorges, using malnourished, mistreated allied prisoners of war. A counter-story in the film, which collides with the main story at the climax, relates to a mission to destroy the newly-constructed railway bridge by a fictitious cloak and dagger sabotage organisation called 'Force 316', whose training base is in Ceylon. In fact, this is a thinly-disguised reference to the real-life Force 136, part of SOE, who indeed had wartime jungle-training facilities in Ceylon at M.E. 25—Horona.
- Carve Her Name with Pride (1958)
- The Guns of Navarone (1961)
- Based on a well-known 1957 novel about World War II by Scottish thriller writer Alistair MacLean. It starred Gregory Peck, David Niven and Anthony Quinn, along with Anthony Quayle (the same Anthony Quayle listed above as serving with SOE in Albania) and Stanley Baker. The book and the film share the same basic plot: the efforts of an Allied commando team to destroy a seemingly impregnable German fortress that threatens Allied naval ships in the Aegean Sea, and prevents 2,000 isolated British troops from being rescued, that were holed up on the island of Kheros in the Aegean, near Turkey.
- Moonstrike (1963)
- A BBC television drama series comprising self-contained episodes of SOE's work in occupied Europe.
- The Heroes of Telemark (1965)
- Operation Crossbow (1965)
- A spy thriller and World War II film, made from a story from Duilio Coletti and Vittoriano Petrilli. It is a highly fictionalised account of the real-life Operation Crossbow, but it does touch on the main aspects of the operation.
- Where Eagles Dare (1968)
- A spy film directed by Brian G. Hutton and featuring Richard Burton, Clint Eastwood, and Mary Ure. The film's screenplay and eponymous 1967 best-selling novel were written almost simultaneously by Alistair MacLean.
- Operation Daybreak (1976)
- Based upon a true, dangerous operation in May 1942 to drop a small group of Czech and Slovak S.O.E. agents into their own occupied country with the singular deadly mission to assassinate Reichsführer-SS Heinrich Himmler's protégé, Reinhard Heydrich, Reichsprotektor (representing the Nazi protectorate over the Czech puppet-state) of Bohemia and Moravia, hated as The Butcher of Prague. The mission succeeded, but with tragic results.
- Nancy Wake Codename: The White Mouse (1987)
