The SAS played a vital role in defeating Hitler – so why did Britain disband them?

Britain’s War Office thanked the SAS for its remarkable efforts in WW2 by abolishing it – yet soon realised the error of its ways. Gavin Mortimer tells the story of how the elite unit reinvented itself to confront the challenges of the postwar world

“Light-hearted banditry”, “ruthless pirating”, a “phantom army” – it’s fair to say that the Special Air Service (SAS) didn’t always attract the most complimentary headlines. In the white heat of the Second World War, when this and other British special forces achieved unlikely successes through a series of daring raids, disparaging press reports could be discarded as merely tomorrow’s chip paper. Nonetheless, they fuelled the impression that the SAS operated outside the rules of the regular British army, and were used as ammunition by some who aimed to whip special forces into line – or even shut them down altogether. That threat became a reality after the conflict ended.

David Stirling, the founder of the SAS, coined a description – “freemasons of mediocrity” – for a certain kind of staff officer who looked upon his men with suspicion and, in some cases, hostility. These ‘freemasons’ regarded the SAS and other irregular outfits – the Long Range Desert Group and the Chindits – at best as private armies, at worst “café gangsters”.

This view extended to the Special Boat Squadron (SBS), which spent the spring of 1944 waging a bloody guerrilla campaign in the Aegean to tie down German troops ahead of the invasion of France. Its actions prompted a sharp exchange between Winston Churchill and Simon Wingfield Digby, the Conservative MP for West Dorset. “Is it true, Mr prime minister,” enquired Wingfield Digby, “that there is a body of men out in the Aegean Islands, fighting under the Union Flag, that are nothing short of being a band of murderous, renegade cut-throats?”

“If you do not take your seat and keep quiet, I will send you out to join them,” retorted Churchill.

One could argue that Churchill was the founding father of Britain’s special forces. It was he, shortly after coming to office in May 1940, who instructed the formation of a commando force to launch a “vigorous, enterprising and ceaseless offensive” against the Axis.

Men such as Stirling, Paddy Mayne (Stirling’s second-in command) and George Jellicoe (the commanding officer of the SBS) first learned the art of guerrilla warfare with the commandos. Churchill’s son Randolph served briefly in the SAS in 1942, and wrote to his father describing how they were destroying dozens of enemy aircraft in daring raids – accounts that made the PM “terribly proud”. When Churchill visited Cairo in August 1942 to discuss the next phase of the north African campaign with his generals, he found time to lunch with his son and Stirling.

Churchill dined with Stirling again at the end of May 1945, following the latter’s release from Colditz, having been captured in January 1943. Stirling had plans to re-deploy the SAS Brigade to the far east, and he wanted to sound out their principal benefactor. But within weeks Churchill was gone, voted out of office by a British public who believed a new leader was required to rebuild the country. The SAS would soon follow the wartime leader into temporary retirement.

Uncertain future

Even if Clement Attlee hadn’t been elected prime minister in July 1945, the SAS and Britain’s special forces might still have faced an uncertain future. The country was practically bankrupt, having spent almost £7bn (a quarter of the national wealth) on the war effort. Defence spending would obviously be slashed, and those ‘private armies’ were an obvious place to start. After all, what was the point in maintaining a guerrilla force now that the war was over?

The SAS paraded for the final time at their Essex HQ on 8 October 1945. Four days later, Brigadier Michael Calvert, commanding officer of the SAS Brigade, sent a memo to 12 of the most senior officers of the SAS, SBS and Long Range Desert Group entitled ‘Future of SAS Troops’. He explained that the War Office had asked for his “recommendations for the future of SAS in the next war and its composition in the peace-time army” as part of its review into Britain’s military capabilities. Calvert feared that the bureaucrats within the War Office – those “freemasons of mediocrity” – were determined to disband the SAS.

One of the most forceful and erudite replies came from Major Roy Farran, DSO and MC, a senior SAS officer who had served in north Africa, Italy and France. He began by stating that, though special forces warfare was still in its infancy, its potential was enormous – particularly because it could exploit the rapid recent developments in air power, communications and motorised transport. “Since it is now so easy to place troops across the enemy lines of communication, I feel that it is important to have a unit of the Special Air Service-type trained to operate individually with the minimum support and with the maximum amount of improvisation,” he wrote.

Farran had already identified Britain’s likely next foe and envisaged how special forces could be used in the event of a conflict. “I believe there will be great opportunities for guerrilla troops in the event of a war against the Soviet Union, which I suppose is the only possibility at the moment,” he told Calvert. Such a war would be either a defensive or offensive one. “In the former case a unit like the Special Air Service could inflict damage on the enemy and slow up his advance out of all proportion to its size… In an offensive war the SAS would increase the speed of our advance by spreading panic and confusion in the enemy’s rear.”

What was the point of maintaining a guerrilla force now that the war was over?

But the prescient Farran also envisaged that, before a large-scale war with the Soviets, Britain could well find itself entangled in insurgencies as its empire began to break up. Counter-insurgency, he declared, was a role to which the SAS and SBS were ideally suited, adding: “If the principle of the SAS does not continue, I cannot believe that the army is thinking along progressive lines.”

Another important figure contacted by the War Office was Lieutenant Colonel Tony Simonds, the commander of MI9’s A Force, who had worked with the SAS in Italy in the autumn of 1943. The main task of MI9 – a secret department within the War Office – was to assist Allied military personnel in enemy territory to evade and escape. Simonds recommended the establishment of three SAS regiments: one for Europe, based in Britain; a second for the Middle East, based in Cyprus; and a third for the far east, based in Singapore.

Simonds wrote that “the role of guerrilla forces in any future war is to defeat the enemy, behind his defended front lines, while the orthodox forces prevent the enemy from advancing”. However, he also suggested that the SAS should “familiarise themselves topographically, militarily, socially and politically with the area. To know and to study the various factions and elements of their area… and to know which personalities should be eliminated should it become necessary in British interest.” That latter role had been the modus operandi of the Special Operations Executive during the Second World War – acting more like secret agents than special forces.

Ultimately, however, the arguments put forward by Calvert and other senior special forces officers fell on deaf ears, and their regiment and units were disbanded.

End of an error

It didn’t take long before the War Office realised its mistake. In January 1946, Jewish paramilitaries in Mandatory Palestine derailed a British train – the first serious guerrilla act in an insurgency that grew increasingly violent as the fight for the establishment of a Jewish state intensified. It was the first of many such insurgencies as Britain’s empire began to fracture.

In 1947, Major Pat Hart, a staff officer in the SAS during the war, learned that the SAS was going to be revived as a territorial regiment under the command of Colonel Brian Franks. Hart was appointed Franks’ second-in-command of 21 SAS – a designation that merged the 1st and 2nd Regiments of wartime fame. According to Hart’s recollection, a War Office study group had been formed in 1946 to re-examine the future of Britain’s special forces. “The result of the study was the recommendation there should be a continuing presence in the army, so the knowledge gained should not be lost, and whilst it could be called anything, probably the best thing was to call it SAS,” he said.

Recruitment began in September 1947. Of the first 200 soldiers signed up, 59 had served with the SAS during the war. One of those was Pat Duggan. “While the majority in the forces were pleased to return to their former lifestyles [in 1945], many of us, hemmed in by the norms of a peaceful civilisation, felt only frustration and spent our time dreaming of, or searching for, something that resembled our wartime role,” he reflected. “When the SAS was reformed as part of the TA [Territorial Army], we homed in like pigeons – a roll-call of the dispossessed.”

Having so many experienced soldiers in their ranks made it easier to train the new recruits in their unorthodox methods. “We were creating an SAS unit that would be available to do any sort of SAS job once it was trained,” explained Hart. “We went off on Nato exercises, as part of the training, and it was very helpful for Nato command to have an SAS unit there.”

The first active deployment of 21 SAS was to Malaya (then a British colony, today peninsular Malaysia) to help quell a two-year-long communist insurgency. The uprising – which the British knew as the Malayan Emergency – threatened colonial rubber plantations and tin mines, so the government called on the talents of men skilled in guerrilla fighting.

“There were a few contacts,” recalled John Gardner of the SAS. “A few seconds, perhaps minutes, of intense shooting, then silence. Blood trails were followed, and some CT [insurgent] bodies were found and brought in, but many blood trails led to nothing… during these weeks we lived in a general state of alertness, even at night half awake, of dirt and sweat, our blood sucked by the many leeches.”

The SAS remained in Malaya throughout the 1950s – years that proved a crucial learning curve for a regiment that was intent on mastering all environments, whether desert, jungle or Arctic.

Johnny Cooper, one of the original 66 recruits to the SAS when the unit was formed by Stirling in 1941, was a squadron commander in Malaya. “We were carrying out trials to develop a two-week ration that was possible for a man to carry,” he recalled. “The object was to avoid the weekly air drops which were a complete give-away and lost us the vital element of surprise.” As a result, the SAS produced a ‘starvation ration’ consisting of dehydrated rice-based food carried in a four-gallon petrol tin.

A global audience

It was no coincidence that in 1952 – shortly after Winston Churchill had been returned to Downing Street – it was decided to raise a regular-army SAS regiment: 22 SAS. Over the following decades, the SAS was sent to fight insurgencies in other remote corners of the British empire and spheres of influence – Aden, Borneo, Oman – before being deployed to Northern Ireland in the 1970s. But perhaps the most high-profile of all its operations occurred in the spring of 1980 when it ended the Iranian embassy siege in London in dramatic style, watched by a global television audience. It was a feat that underlined the regiment’s reputation as the world’s pre-eminent special force.

Strength and skill were respected, but so were other qualities, such as a cool head

Throughout these operations, one aspect of the SAS was immutable, and that was the temperament of each recruit. In 1956, Dare Newell, the SAS regimental headquarters major, wrote to several wartime special forces officers to ask what characteristics they thought essential for an SAS soldier. From their answers he compiled the selection criteria.

“A man’s personal qualities and make-up count more than technical efficiency in his own arm of the service. Technical efficiency can be taught; the personal qualities required for long-range, long-term operations in enemy territory, however, are part of a man’s character and, although they may be developed over a period, they must be learnt in childhood.” The qualities deemed essential were initiative, self-discipline, independence of mind, ability to work without supervision, stamina, patience, and a sense of humour.

These characteristics continue to underpin the SAS ethos today. Warfare and weaponry evolve, but not human nature. One of the 12 recipients of Mike Calvert’s worried memo in October 1945 was Major John Verney of the SBS. “We came to know one another’s physical and mental capacities, and with them our own,” he said of his wartime service. “Strength and skill were respected, and a fair degree of both were essential, but there were other qualities, such as a cool head, or a good temper, that might well prove more valuable.”

CLONE WARS

Countries worldwide have established forces based on the British SAS template

The reputation of the SAS, encapsulated by its ‘Who Dares Wins’ motto, is global. Its influence is evident in France’s 1er Régiment de Parachutiste d’Infanterie de Marine (1erRPIMa), the US Delta Force and Germany’s GSG 9. New Zealand and Australia have their own SAS regiments, both raised in the 1950s and using the same motto as their British counterpart. It is also alleged that the SAS has trained Ukrainian special forces for many years. The wartime SAS included two regiments of French troops who fought under British command. In June 2024, to mark the 80th anniversary of the Normandy landings, President Emmanuel Macron visited the French SAS memorial in Plumelec in Brittany. According to France’s Ministry of Defence, the 1erRPIMa “has its roots in the SAS of World War II, [and] is based on daring, determination and endurance”; its motto is Qui ose gagne – a direct translation of that of the British SAS. The founder of Delta Force, Charles Beckwith, was one of America’s most innovative military thinkers in the late 1950s. A member of the 7th Special Forces Group (Airborne), Beckwith was posted to 22 SAS as part of an exchange in 1962. During that time, he conceived the idea of an American equivalent. On his return to the US, Beckwith received encouragement from General Sam Wilson, a Second World War veteran who had been trained by the British Chindits in south-east Asia. In a 2016 interview, Wilson explained that he had met David Stirling in the course of helping to establish Delta Force. Like Delta Force, Germany’s counter-terrorism unit GSG 9 was formed in the 1970s in response to a series of high-profile terrorist atrocities. When GSG 9 rescued all hostages from a hijacking at Mogadishu airport in Somalia in 1977, it was assisted by two SAS soldiers.  Over the course of three decades, David Stirling’s band of “renegade cut-throats” had become a blueprint for special forces units across the globe.
