I've tried to be as accurate and thorough as possible but it's difficult to get this stuff spot on, if you notice anything wrong please drop me an e-mail.

History of the Special Air Service

But first a quick history lesson…

It is 1941 and British Commonwealth forces stand alone fighting occupying German and Italian forces; most of Europe is under the control of Axis forces (the bad guys) and British land forces (the good guys) are struggling against the German war machine. However, in the deserts of North Africa the British are progressing against the Italian army, pushing them back to El Agheila forcing the Italians to ask Hitler for assistance. Hitler's response was to send General Rommel who lead the Africa Corps, he soon manages to push back the weakened British forces in to Egypt, all except the largely Australian army who managed to hold on to the coastal seaport of Tobruk for 240 days until liberated by advancing British forces, who were then pushed back again, and then advanced again! Anyway…

Also around this time (from around June 1940 onwards) was the idea of 'Commando' units, also called 'Special Service' units. This was the relatively new idea (to British officers anyway) of having small, highly trained, very fit men launching small hit and run raids on priority targets. The objective, to destroy stuff (vehicles, ammo and fuel dumps, local infrastructure etc) and reconnoitring targets (troop numbers, insertion points, lay of the land.) Bringing with it the added bonus of tying up enemy units, by making them guard bases more heavily and demoralising the enemy. The idea of these forces was resisted by many in the upper commands of the British army who resented the drain it took on the man power, but also resented the tactics used by these forces. However the idea had a powerful backer in the form of the British Prime Minister Winston Churchill who recognised the usefulness of these units and the morale boost they could offer the British public.http://en.wikipedia.org/wiki/British_Commandos

One such unit was Layforce, made up of troops from various Commando brigades 'it consisted of around 2000 men within 3 commando units (7, 8 and 11 commando) but each were hampered by a chronic shortage of man power and supplies resulting in two of the three large scale operations mounted by Layforce failing. Seizing upon these failures the Army brass disbanded Layforce in August 1941 deploying the men elsewhere.' (A - Z of the SAS, Peter Dartmen. p100)
http://en.wikipedia.org/wiki/Layforce

In July 1941 a member of 8 commando, Layforce was injured and on crutches after a parachute jump; 24 year old Captain David Stirling believed in the idea of the Special Services and set about devising a plan that could continue the work of these units but with fewer men and a smaller drain on other resources. Knowing the hostility that existed towards such forces within the officer class Stirling stormed in to the British General Headquarters in the Middle East to gain the Commander in Chief's (General Claude Auchinleck) personal permission to form a Special Service.

Against the advice of many of his senior staff Auchinleck gave Stirling permission to recruit four officers and sixty men into a new unit called the 'L detachment to the Special Air Service Brigade,' a name that was given to convince the Germans that the unit was attached to a much bigger airborne commando brigade, despite no such unit existing (the idea of airborne commandos was also in its infancy). Most of the recruits (all volunteers) came from Stirlings previous unit No 8 Army Commando, Layforce now disbanded.
Jock Lewis and Paddy Mayne were two of the first officers and are now legends of the SAS. Bob Bennett and Johnny Cooper were two of the first non commissioned soldiers to join the regiment.
In 'Story of the SAS - dvd' they describe what they found when they arrived at their new base.

Bob Bennett
"We all rolled along to Kabrit, which was a point on the canal that was picked as a camp site and we were on a three tonne truck, we stopped and there was absolutely nothing, no camp, nothing. And David Stirling said, 'well this is it, your first operation will be to steal a camp' and that night we drove down about two miles to a Kiwi camp and the Kiwi's had gone up the desert so the place was empty so we took everything we wanted."

Johnny Cooper
"We nicked fourteen tents and a piano, we thought it might come in handy but we could never find anybody to play it."

All of the recruits had come from Commando regiments; however the training was devised to weed out those who were not tough enough both physically and mentally. As such, extreme fitness, individualism and expert weapon handling were the criteria for members of the new unit.
Despite sill being a technique still in its infancy Stirling decided that the SAS would insert via parachute and so Jock Lewes took over as the ad hoc parachute instructor devising training methods as affective as jumping from a moving truck and trying not to kill yourself.
It is now 16th October 1941 and the first jump did not go well; two men were killed when their chutes did not open, Stirling quickly diagnosed and solved the problem and as a prime example of his leadership, he was the first man to jump on the next training exercise.

The First operation was on the night of the 16th November 1941. Operation Crusader was to launch on the 18th November as an attempt to kick Rommel out of Cyrenaica (North Libya) and liberate the besieged seaport of Tobruk. Stirling's men were given the task of destroying targets at two airfields at Tmimi and Gazala to stop advancing ground forces coming under attack from Axis aircraft there, it was a disaster, the men jumped in to near hurricane force winds during a desert sandstorm and of the sixty-five that jumped, only twenty-two made it back to the pre-arranged extraction point with the Long Range Desert Group (LRDG), no German aircraft were attacked. The 17th November 1941 is considered by the modern SAS to be their official 'birthday' in celebration of the mission.
Stirling's response to this disaster was to use the Long Range Desert Group to infiltrate and exfiltrate from missions. http://en.wikipedia.org/wiki/Lrdg

On the 12th December 1941 the next raid was mounted jointly with the LRDG, the objective was to destroy aircraft when they are at their most vulnerable on the ground, at an airfield on the coast of the gulf of Sirte. They were dropped near to Tamit, an airfield (I think Italian) where they planted explosives in the underground bomb dump, after coming across a building Paddy Mayne kicked the door in and opened up on the occupants, carrying on they spotted aircraft on the ground so they proceeded to plant explosives on them until they ran out. After that they just hacked away at planes by hand, causing as much crippling damage as possible. Mayne went back on the 24th December and attacked again, reportedly destroying twenty-seven aircraft on the ground (A-Z SAS. P178) This mission was soon followed by a raid on the Agheila airfield on the 14th December 1941, then a raid on Agedabia airfield on the 21st December in which thirty-seven Italian aircraft were destroyed and then another raid followed on the 24th December again on Tamit airbase where they destroyed twenty-seven aircraft. (Story of the SAS) These missions were a great success and the idea of the SAS as being a hit and run squadron was starting to take shape, they were given permission to recruit new men as well as being attached a group of fifty Free French Para troopers who began operations in March 1942.

Also around this time saw the introduction of the modified Willys Jeeps, fitted with twin Vickers K guns or 0.5inch Browning heavy machine guns, armour plating to protect the gunner and driver, a field radio, spare ammunition, fuel and water. These jeeps made the SAS independent of the LRDG (who were finding it more difficult to their job whilst transporting the SAS around the desert) and replaced the idea of planting bombs on planes and instead the SAS would simply drive onto an airfield in a column, race down the airstrip alongside the parked planes and let rip destroying as much as they could before driving off and disappearing into the desert night. These raids proved very successful throughout the North Africa campaign and have gone down in SAS folklore ever since.

Now we need to hop back briefly and get a little confused because in the Spring of 1941 there existed a unit called the Special Boat Section, there also existed a unit called the Special Boat Squadron, established in 1940. Both of these units were rapid raiding units that launched from submarines and canoed ashore destroying soft targets such as railway and communication lines and performing reconnaissance. Now at some point in 1941 both units were attached to Stirling's old unit, Layforce, after Layforce was disbanded in August both units carried on independently, launching raids etc but inevitably by the end of 1941 both units had sustained heavy casualties. Now it would seem that Special Boat Section was absorbed in to L Detachment of the SAS at the end of 1941 and the Special Boat Squadron were absorbed a year later in November 1942. Anyway the up-shot of this is that by 1942 the SAS were able to launch amphibious raids and reconnaissance, the end.

Now in October 1942 L Detachment to the Special Air Service was re-named 1 Special Air Service and by January of 1943 Stirling had under his command a French Squadron (94men), a Greek Sacred Squadron (114men), Special Boat Section (SBS) (55men), 1 SAS (390men) and the Special Interrogation Group who were a short lived group of twelve Jewish, German speaking immigrants who were put to work intelligence gathering. (A-Z SAS, p.167/168) However also in January 1943 whilst out on a raiding mission Stirling's unit was discovered camped, they split up 'every man for himself' was the order from him and he was captured by the German forces, escaping four times before being moved to Colditz Castle. Paddy Mayne now took over command of 1 SAS which in April 1943 was renamed the Special Raiding Squadron whilst fighting in Sicily and Italy but becomes 1 SAS again later in the year. Also in April the waterborne element of the SAS, become a separate unit; the Special Boat Squadron (SBS). Then in May 1943 David Stirling's brother William creates 2 SAS in Algeria, a unit created in the image of 1 SAS now the SRS, confused yet? I am.

By May 1943 the North African campaign was over and the allied attention turned to Sicily and then on to Northern Italy, although there was disagreement between the British who felt they should re-take the Mediterranean and Greece first and the Americans who wanted to go into Italy. Both agreed however that Sicily was the next logical target. In the meantime the newly formed SBS was tasked with coastal raiding in the Mediterranean and Aegean Sea.
The coming campaign saw the SRS now starting to be misused, being used more as commando shock troops rather than conducting hit and run style raids, intelligence gathering and sabotage operations deep behind enemy lines which is what they were trained for.
The Sicily campaign starts with Operation Husky, the plan was to capture the Island of Sicily giving them a launching pad into Italy and Europe and they hoped the capture of Sicily would lead to the downfall of Mussolini (the Italian Prime Minister and dictator) which it did.
The SRS and 2 SAS launched various missions in support of the allied landings with mixed success, the most notable of the operations being Operation Narcissus and Chestnut. Operation Narcissus was a '40-man detachment of A Squadron, 2 SAS, on July 10 1943 ordered to attack and capture artillery positions at a lighthouse on the coast of Sicily but when they got there they found it deserted. Operation Chestnut was a mission to drop two teams in to Northern Sicily to disrupt communications and the transport infrastructure (blow up bridges, train tracks etc) however both teams suffered from faulty equipment and by being parachuted to close to targets and with men to widely scattered. There were some successes with the SRS assaulting Capo Murro Di Porco on the South East Pennisula of Sicily and the town of Augusta two days later.' (A to Z SAS. P161) By the 17th August 1943 Sicily was captured.

The capture of Sicily now meant the Allies could move into the South of Italy, the SRS were the tip of this attack. Operation Baytown was launched on 3rd September 1943, the allies wanted to capture the Port of Bagnara and the SRS were tasked initially with disrupting enemy lines of communication and then with the capture of the town. Despite problems with the landing the SRS captured the town meeting with only moderate resistance but was followed by three days of skirmishing in the hills surrounding the town which ended when regular troops advancing from the South arrived at the town. The SRS and 2 SAS continued to fight in Italy, beyond the surrender of Italy in September 1943 and into 1944/45 against the Germans but the story is largely one of missed opportunity, poor planning by senior officers and poor preparation. They conducted several operations against railway lines and bridges a few of which were very successful but many failed. There was one disastrous attempt by a four-man patrol to attack an airbase resulting in one man killed one captured (and later escaped). Several attempts to meet up with escaped or released (after the surrender if Italy) POW's but these were hampered by bad planning and poor organisation. (Quite often when you read about these missions, that are uncharacteristic of the SAS you hear about, they failed either because of poor communication equipment, radios were often damaged on parachute landings or because of bad insertions ie. scattered parachute landings, inexperienced parachutists and poor naval co-operation.)

Towards the end of the Italian campaign the SRS were having some successes harassing German troops and infrastructure in the North of Italy, there were two large actions of note. In October 1943 the SRS along with a commando brigade attacked the town of Termoli; the town was captured and was strategically important in the attempt to break the 'Termoli Line', the action was followed by fierce fighting against German counter attacks which were repelled by the arrival of Irish Rangers and Canadian tanks. (A-Z SAS. P178/179) Later on in March 1945 2 SAS were dropped into Northern Italy with the objective 'to harass the enemy', a mission much more suited to their training and origins. They quickly established an alliance with local resistance fighters and escaped Russian POWs' and their first and bold mission lead by Major Roy Faran was to attack the German HQ at Albinea, however they were eventually driven back. They continued harassing local German troops, launching mortar attacks and ambushes and even repelled a German attack on their own base. The mission ended at the end of April 1945. (A-Z SAS. P.180/181)

At the end of 1943 the Special Raiding Squadron reverted back to being named 1 Special Air Service (1SAS) and then later in January 1944 was put under the overall command of the 1 Airborne Corps. It was named the Special Air Service Brigade based at Hylands Hall, Chelmsford and consisted of a "HQ French Demi-Brigade, 20 Liaison HQ (the SAS link with the Free French), 1 SAS, 2 SAS, 3 SAS (a French Parachute Battalion), 4 SAS (a French Parachute Battalion), 5 SAS (Belgian Independent Parachute Battalion) and F Squadron, General Headquarters (GHQ) Liaison and advanced reconnaissance Regiment." (A-Z SAS. P168)

In June 1944 the Allied Forces were ready to invade France from bases throughout the South of England. Huge Secrecy surrounded the shear numbers of troops in England at that time and a massive diversionary plan existed in an attempt to convince the Germans that the main landings would be in Norway and Pas de Calais (the most logical location as it was the closest point to England.) On the eve of D-Day (the actual landings at Normandy) airborne troops were dropped to secure targets and tie up enemy troops but also to convince the Germans that a huge airborne force were being landed in France. http://en.wikipedia.org/wiki/Operation_Fortitude

The SAS were dropped in behind enemy lines on the eve of D-Day on the 6th June in support of the deception plan they were to mount hit and run attacks on local troops, and make a lot of noise to convince the Germans that there were a lot of them. Sadly the latter part of the plan failed as (once again) troops were to widely scattered on landing as was their equipment. However the first part plan of the plan was a success. Troops from 1SAS meeting up with Maquis forces (French resistance) and establishing a base in the wooded hills around the town of Dijon were able to carry out hit and run raids on troops, destroy railway lines, vehicles and provide intelligence on troop movements, numbers and positions. They also gave intelligence on targets for the British RAF which to this day remains one of the SAS' main missions. Poor Marquis security meant the SAS frequently moved camps and lived away from the Marquis forces; pressure from the Germans was hard though and locals suspected of assisting the SAS were often shot and the SAS had to fight off German attacks on their bases.
One such leak lead to the death of over 33 SAS men, during Operation Bullbasket, a very successful operation in support of the D-Day landings the location of the SAS base was leaked and the Germans attacked it on 3 July 1944, 33 troopers (probably in uniform) were captured but were later executed (if they were in uniform this violated international law and the excepted rule that you would take soldiers prisoner until the end of the war.) Despite such drawbacks SAS operations in France were hugely successful. A small team would initially be inserted to meet Marquis forces and establish an appropriate landing zone (LZ) then larger numbers of men and equipment would be dropped. Once a base was established raids were mounted and intelligence gathered with units operating anywhere up to three months at a time before being rotated out by another squadron. The targets hit remained the same throughout the war, railway lines and bridges were hit, re-built then hit again, ambushes on enemy troops and vehicles were launched, locations of bases, vehicles, factories, fuel and ammunition dumps were given to the RAF who's subsequent attacks were devastatingly effective. By the end of the war the SAS were operating in France, then Holland, Belguim and Germany they were credited "with around 2000 men killed, or wounded 7733 enemy soldiers and captured a further 4784 destroyed 700 vehicles, 7 trains, derailed 33 and cut railway lines on 164 separate occasions" with this list omitting the valuable reports to the RAF and intelligence sent back to HQ. (A-Z SAS. P133)
Towards the end of the war in Europe the SAS Brigade was lead by 'Mad' Mike Calvert until its disbandment. After the War the SAS was used to search for suspected war criminals and was in charge of disarming German troops in Norway during Operation Apostle until the SAS was disbanded in October 1945.

However the name Special Air Service pops up again in 1947 when the War Office decides to form a Territorial Army raiding unit which soon becomes merged with the Artists Rifles and is known as 21SAS Artists Rifles. Then 'Mad Mike' re-appears in Malaya, sent there by the British to work out how best to combat communist guerrillas in the jungles there. It is now 1950 and Mike forms a unit called the Malayan Scouts (see Malaya in the Operations pages) to which a detachment of the 21 SAS Artists are attached, in 1952 the Malayan Scouts are re-named 22 Special Air Service forming the modern SAS. (A-Z SAS. P.168 & P.32)

I will write pages on all these operations as soon as I can.
