The 007 factor
A hollow fake tree trunk, one of many devices created at 'The Thatched Barn'

To give agents an edge in combat SOE employed budding scientists to invent unique weapons of war.
At The Frythe, a secluded house near Welwyn Garden City, Hertfordshire university graduates invented devilish devices such as the single-shot cigarette pistol and the Sleeping Beauty - a submersible canoe. SOE workshops also created carborundum - an abrasive grease when smeared on the right spot could bring a locomotive to an immediate standstill.
In North London, The Thatched Barn, a former roadhouse, became the headquarters of the ingenious Camouflage Section run by film director Elder Wills. Here an army of ex-prop makers were put to work creating countless illusions out of papier maché or plaster - many of them deadly!
One tree trunk mould might conceal radio equipment but another shaped like a piece of camel dung hid a booby trap that could blow the tyre off an enemy truck.
Other branches of this backroom operation included the False Documents Section where agents collected their bogus identities and even a fashion company that outfitted agents with suits and dresses cut to the Continental style.
Enemies within
The Secret Intelligence Service (SIS) - now known as MI6 viewed SOE with great suspicion.
Head of the SIS, Sir Stewart Menzies, stated repeatedly that SOE were 'amateur, dangerous, and bogus' and took it upon himself to bring massive internal pressure to bear on the fledgling organisation. SIS did not want SOE disrupting their agents intelligence-gathering operations by blowing up bridges and factories.
Bomber Command also despised SOE and resented having to loan aircraft for 'unethical' clandestine missions. They wanted to win the war by bombing Germany to its knees.
But with Churchill as their guardian SOE survived and lived to fight another day.
Lonely courage
Captured agents faced interrogation, torture and execution at the hands of the Nazis

The life expectancy of an SOE wireless operator in Occupied France was just six weeks...
Complicated coding and decoding procedures left Wireless Telegraph (W/T) operators with no choice but to transmit for long periods of time. This gave German military intelligence, the Abwehr, ample time to find their quarry using radio detection vans.
The Germans knew that W/T operators were the weak link in the chain of any agent network. In Holland the Abwehr played the Englandspiel - 'the match against England' - by controlling the wireless traffic of a captured SOE operator. Dozens of agents fell straight in to enemy hands as result - most were eventually shot.
The Abwehr were a deadly foe, but not as ruthless as the Gestapo or the SS Sicherheitsdienst, who tortured their victims before execution.
Finest hour
By D-Day on 6 June, 1944 SOE had become a feared organisation that could strike the enemy anytime, anywhere.
Agent networks now stretched across Occupied Europe, linked to an army of resistance fighters. When the Allies landed, SOE struck with venom.
One immediate target was the 'Das Reich' 2nd SS Panzer Division, which began to march north through France towards the Normandy beaches. SOE agents siphoned off all the axle oil from the division's rail transport cars, and replaced it with abrasive grease - all of them seized up.
On the roads Das Reich columns were constantly ambushed, allowing the RAF to wreak havoc. This crack division was delayed for 17 days, by which time the Allies had a firm foothold in France.
SOE kept the pressure on the enemy in the mountains of Yugoslavia and northern Italy. In Genoa, 600 partisans took the unconditional surrender of 12,000 German troops, with SOE at the centre of the negotiations. The price of freedom was high, but SOE accomplished their mission to the letter.
In May 1945 General Eisenhower wrote that 'the disruption of enemy rail communications, the harassing of German road moves and the continual and increasing strain placed on German security services throughout occupied Europe by the organised forces of Resistance, played a very considerable part in our complete and final victory.'
With no war to fight, SOE survived until January 1946 before being disbanded forever.
