Ctrain, arguement is not a problem but you cannot argue about results. If the allied forces did not think disinformation was important would they have spent so much time and energy on it with a major invasion in the works.
The key element of Fortitude South was Operation Quicksilver. It entailed the creation of the belief in German minds that the Allied force consisted of two army groups, 21st Army Group under Montgomery (the genuine Normandy invasion force), and 1st U.S. Army Group (FUSAG) (a fictitious force under General George Patton), positioned in southeastern England for a crossing at the Pas de Calais.
At no point were the Germans fed false documents describing the invasion plans. Instead they were allowed to construct a misleading order of battle for the Allied forces. To mount a massive invasion of Europe from England, military planners had little choice but to stage units around the country with those that would land first nearest to the embarkation point. As a result of FUSAG's having been placed in the south-east, German intelligence would (and did) deduce that the center of the invasion force was opposite Calais, the point on the French coast closest to England and therefore a likely landing point.
To facilitate this deception, additional buildings were constructed; dummy vehicles and landing craft were placed around possible embarkation points. Furthermore, Patton was often photographed visiting these locations. It was originally intended to make many such fakes, but the extremely low level of German aerial reconnaissance and the belief that most German spies were under British control meant that such effort were reduced to a minimum. A huge amount of false radio traffic was transmitted, commensurate with a force of that size.
A deception of such a size required input from many organisations, including MI5, MI6, SHAEF via Ops B, and the armed services. Information from the various deception agencies was organized by and channeled through the London Controlling Section under the direction of Lieutenant-Colonel John Bevan.
The Allies were able to judge the effectiveness of these strategies. ULTRA intelligence — that gained from the breaking of German codes and ciphers, such as the Enigma machine — was able to provide an indication of the German high command's responses to their actions. They maintained the pretence of FUSAG and other forces threatening Pas de Calais for some considerable time after D-Day, possibly even as late as September 1944. This was vital to the success of the Allied plan, since it forced the Germans to keep most of their reserves bottled up waiting for an attack on Calais which never came, thereby allowing the Allies to maintain and build upon their marginal foothold in Normandy.
So convinced were the Germans by this deception that they ignored several "leaks". One such leak was the crossword that came out in The Herald and Review six days before the beach landings were to take place. Some of the answers consisted of Overlord, Neptune, Gold and other key terms to the invasions; the US government later declared that this was just a coincidence. Through the Cicero affair, the Germans obtained documents containing references to Overlord, but these documents lacked all detail. Double Cross agents, such as Juan Pujol (code named Garbo), played an important role in convincing the German High Command that Normandy was at best a diversionary attack. U.S. Major General Henry Miller, chief supply officer of the US 9th Air Force, during a party at Claridge's Hotel in London complained to guests of the supply problems he was having but that after the invasion, which he told them would be before 15 June supply would be easier. After being told, Eisenhower reduced Miller to Colonel and sent him back to the U.S. where he subsequently retired. Another such leak was Gen. Charles de Gaulle's radio message after D-Day. He, unlike all the other leaders, stated that this invasion was the real invasion. This had the potential to ruin the Allied deceptions Fortitude North and Fortitude South. For example, Gen. Eisenhower referred to the landings as the initial landings.
