Allied Military Deception

The British were always coming up with deception plans in WW2. Perhaps because they couldn't rely on overwhelming manpower and firepower to win battles.

Alam Halfa- giving false maps of good tank ground. Successful.

Alamein - Dummy trucks and tanks. Tactical surprise achieved.

Operation Torch - Passed off as a Malta convoy. No ships lost to U Boats.

Patton leading the main Allied invasion in the Pas de Calais - Use of wireless traffic and fake formations. Pretty much a glorified version of the Alamein deception. Successful.

Operation Mincemeat. Successful

Use of double agents to give false info on where the German V weapons were landing in England. Largely Successful

Many smaller ones from air raids to convoys

I certainly think that is true in part as the British didn't have 40% of the world's industrial production pre-war like the US. But, also because they had been in the game of European wars a very very long time and gotten good at fighting nations with huge land armies with their smaller armies.

I'd dispute that by saying that the deception was integral to Soviet military operations and used frequently throughout the war by the Red Army. For the Vistula-Oder Offensive they were able to achieve 10:1 superiority in infantry and artillery in their main breakthrough sectors, while using deception to convince the Germans that they only had a 3:1 advantage, and weren't in assault concentrations. Earlier during the Bryansk Offensive operation Popov expertly shifted 50th army to his Front's right flank, replacing the 10th army in secret, while replacing 50th army with the 3rd army; all well camouflaged. This series of regroupments, only partially detected by the Germans, allowed for a rapid breakthrough towards and across the Desna. Military deception is just very useful.

I never said the Soviets didn't use deception. They did. In fact deception in both military and political matters was pretty much what Soviet communism was about.

Operation Torch - Passed off as a Malta convoy. No ships lost to U Boats.

I have identified at least four misdirects for the Torch convoys. When the Eastern Task force convoys were assembled in the UK differnt spys were fed differing stories: One of the old Sledgehammer plans was used to warn of a late October invasion of France. B. Convoy to Egypt. This was also applied to the Western TF convoys from the US to Morroco. C. Malta relief. D Invasion of Sardinia and/or Sicilly.

In the case of A. the German garrisons in France were alerted and got a work out moving from their training sites in the interior to reserve assembly areas near the coast. The Brits also got a value out of this as they carefully monitored the German reactions and saw how the reserves were deployed and how long it took them to move about.

B. Caused several German & Italian submarines to be redirected to the central Atlantic route used by the convoys to the African Horn. That put them two days out of position to intercept the Western TF headed for Morroco.

When Hitler got the memo that a Allied fleet was entering the Mediterrainian he guessed C. This was not so outlandish. The Italian garrisons on both Sardinia & Sicily were very understrength & Sardinia had less than 130 operational combat aircraft present.

The French North Africa colonies were considered, but Hitler & other German leaders thought Sardinia very vulnerable and a better target than Algeria or Tunisia. Conversely it seems the Italians placed the French as the most likely target.

I was responding to the fact that you said that the British used deception because they couldn't rely on firepower, but it seems to me that even if they had the firepower deception would still have played an integral role in their operations, as it did with other powers.
 
The Oncoming Storm said:
The British spotted what was going on and sent a Mosquito that dropped a single wooden bomb on it! Don't know if its true but its a good story! ;)
:D:D Who says war can't be funny?:p

There's also the bombers dropping Window to simulate the landing forces before Neptune went ashore.

I've also heard the Sovs had at least one dedicated radio station putting out nothing but fake signals.

There's also the deception op in conjunction with Judgement.

So I was reading David Glantz's Soviet Military Deception in the Second World War, which offers a comprehensive study of the Red Army's use of tactical, strategic, and operational deception. I was wondering if there were comparable Allied deception efforts? By that I mean not just strategic misinformation like before the D-Day landings, but also prior to various battles and offensives, including in North Africa?

There was an extensive deception effort
before the British counterattack at El Alamein.

There was Operation Mincemeat ("The Man
Who Never Was"), which deceived the Germans
about the Allied invasion of Sicily.

One last bit of deception was staged in 1945:
an imaginary minefield in a key location to
deny its use to U-boats.

(U-boats running on snorkel were very hard
to detect, but had great difficulty in navigation.
South of Ireland there is a conical seamount;
a U-boat using its depth sounder could find the
peak and thus fix its position. Through a
double agent, the British passed information
that a minefield had been laid there. The
Germans ordered the U-boats to avoid a 100 km
square area centered on that seamount.)
 
When Germany was hammering southern England with the V-weapons, they took to using BBC reports on the damage for adjusting their aim. When the British caught on, the BBC started broadcasting false damage reports that tricked the Germans into either overshooting or undershooting their intended targets.
 
Hmm... does the fictional network of Joan Pujol Garcia count as an allied effort? He was sort of a private imitative.

He did begin it as a private initiative, but the entire network was mounted thanks to the help of the Double Cross Committee, the group in charge of the "German" spies in Britain.

Most of those agents were developed with the help of MI5 (or was it MI6), and he was himself in the pay of the agency at the times, so yes it would count, although the stuff he did before the British found him wouldn't count.

Not in the same vein as the others, but IMO X-Gerät and Y-Gerät must count since they were forms of deception. As well, there's the little stuff, like Airborne Cigar and Tinsel (the latter wasn't hugely successful, but did make the Germans' job a bit more difficult).
 
I remember seeing a documentary around the 50th Anniversary of D Day that showed many of the techniques used in Fortitude. Apparently once the Germans realised they had been deceived they tried to adopt it for their own use and constructed a fake armoured division in France. The British spotted what was going on and sent a Mosquito that dropped a single wooden bomb on it! Don't know if its true but its a good story! ;)

I've heard version that this happened with Soviet defenses around Leningrad and Germans dropped wooden bomb.

So overall I doubt it was true, most likely it was a joke somebody made "You know, we keep building wooden tanks and soon enemy will start dropping wooden bombs on them" and then people just ran with it.....
 
A lot of the operational deception had been part of the British repertoire since 1917/18, there was a mini Fortitude involving the relocation of the Canadians prior to Amiens, fake wireless stations, barrages to hide tanks coming up etc.

Te amazing thing is no the level of deception practiced by the allies but the frequency with which the Germans fell for it, whch says something about how well planned it was - always tell them what they want o hear, then stamp on their gonads
 
There are only 2 that I know of, and they've been mentioned already, but who cares.

There was Operation Mincemeat - Faked plans to invade Greece (IIRC) to divert forces away from Sicily

There was also FUSAG (First US Army Group) - Stationed in Kent opposite Calais to reinforce the German's belief's that Pas-de-Calais would be the real invasion. It only existed on paper and in the minds of the Germans - created by inflatable tanks, trucks, planes, radio transmitters in the back of lorries moving around to give the impression of a large group of men etc.

There were also numerous diversions during Luftwaffe's bombing campaigns of Britain - faked airfields created by 1 person holding a lamp/torch and running it along the ground to imitate a plane's lights when taking off; Large groups of fires, lights etc to give impression of burning cities to divert Luftwaffe from real targets
 
I always loved this one, the deception that the British had the ability to set the sea on fire, so well believed that it is still mentioned today as "fact". The best bit of this is that part of the deception included the removal of burnt bodies from the sea dressed in German army uniform. Obviously this was not meant to fool the Germans, they knew they had not attempted to invade, but was used as a morale booster.

On 25 September, British coastal defense units were told that "a scheme was afoot to produce an impenetrable barrage of flame on the sea to prevent or destroy enemy ships attempting a landing." Flame barrages were recommended at the following localities; Bawdsey, Mouth of River Deben, Mouth of River Orwell, and Felixstowe, from Ferry to Landguard Fort. No flame barrages were installed further north than Shoeburyness. There are still those who believe the story. In the midst of researching this propaganda campaign, I received this letter:
My father who is now 90 was stationed on the South Coast in WWII somewhere near Hythe and he can clearly recall burnt bodies being pulled from the sea dressed in German ARMY not Navy or Air Force uniforms. They were all taken to a makeshift mortuary and the troops involved were each individually reminded of the penalties for breaking the Secrets Act and one officer of the unit was taken away after having discussed it with another unit commander. What exactly happened there he cannot say but he is convinced this had something to do with the operation you talk of.
It is hard to determine if this was a successful black propaganda campaign. Although it might have caused the Germans to think more cautiously, it is doubtful that it stopped the invasion. The British rumor that a small German landing had been repulsed, and later that a large invasion flotilla had been incinerated halfway across the Channel did spread across occupied Europe and to America, then filtered back to Britain. It might have encouraged the occupied nations to believe that the war could still be won, and may have helped Americans believe that Great Britain would be able to block an invasion. It probably had little effect on the Germans since they clearly knew that they had not attempted to invade England. In truth, It was Göring's inability to defeat the Royal Air Force that stopped the invasion. But, perhaps the rumors helped, and certainly they gave support and hope to the British and the occupied people of Europe.

Before we leave this deception campaign we should mention that there were dozens of such stories being written and disseminated by the British. Besides leaflets, newspaper and radio stories, in an attempt to raise the morale of occupied Europe and lower the morale of the German military, civilians and their allies, the secret British “Underground Propaganda Committee” produced well over eight thousand rumors, (they called them “Sibs” from the Latin sibalare – to hiss). Researcher Lee Richards mentions the “whisper campaign” and many of these rumors in his book Whispers of War, Psywar.org, 2010. In regard to British propaganda rumors about the dangers of a cross-channel invasion and British secret weapons he lists dozens of moral-destroying rumors. The British were clearly working overtime attempting to make the invasion look like a perilous undertaking. I have selected a few of the more interesting ones:
13 July 1940 – Britain has a new and deadly sea mine designed for the special purpose of preventing the landing of German troops in shallow-draught boats…Another type of mine is concealed beneath the runways of airfields. It cannot be seen from the air and is remote controlled. It will destroy German aircraft attempting to land troops on British airfields.
27 July 1940 – Britain has a wireless controlled bomb-carrying aircraft…
27 September 1940 – The British have a mine dropped from aircraft that spreads a thin film of highly inflammable liquid over the surface of the water…
17 October 1940 – The British have perfected a flamethrower for use in their aircraft…
31 January 1941 – Two hundred sharks have been sent from Australia to Britain and released in the Channel.
I particularly like that last one because in December, 2010, after a string of shark attacks in Egyptian waters, the South Sinai Governor stated that this could be a plot to destroy Egyptian tourism by the Israeli Mossad. A good rumor never dies.

"I Was Monty's Double"

http://en.wikipedia.org/wiki/I_Was_Monty's_Double_(film)

A few months before the D-Day landings during World War II, the British government decides to launch a campaign of disinformation; spreading a rumour that the landings just might take place at a location other than Normandy. The details of the operation (actually, there were several such operations) are handed to two intelligence officers, Colonel Logan (Cecil Parker) and Major Harvey (John Mills). They are initially unable to devise such a plan - but one night, Harvey sees an actor at a London theatre, who looks just like General Bernard Montgomery.
Logan and Harvey discover that the actor is M. E. Clifton James (playing himself), a lieutenant stationed in Leicester with the Royal Army Pay Corps and that he was a professional actor in peacetime. He is called to London, on the pretext that he is to make a test for an army film, and a plan is devised that he should tour North Africa, impersonating "Monty".

The intelligence officer who initially recruited James was David Niven, at that time serving as a lieutenant-colonel at the War Office.
