Ghost Army: The First US Army Group

Today is the 69th anniversary of the Normandy landings and one of the defining moments of World War II. Many thousands of brave men died on the beaches due to heavy German resistance in some places, especially Omaha Beach. However, many more men may have died, and indeed the invasion may not have succeeded were it not for Operation Quicksilver: the Allied intelligence operation intended to draw German units away from Normandy and otherwise confuse the Germans into thinking the invasion was going to happen somewhere else.

While the main invasion was at Normandy, the Germans
believed it would come at Pas de Calais to the north.

The thinking behind this operation is clearly shown in the 1970 film "Patton", because General George Patton would play a vital role in the deception. In the midst of the fallout from Patton slapping a battle-fatigued soldier in front of the press, Patton was removed from command of the Seventh Army and temporarily relieved of duty.

However, the Germans followed his movements very closely, due to their belief that he was the Allies' best commander and he would be in charge of the eventual invasion of Europe. The Allies sought to use this and placed Patton in 'command' of the First US Army Group.

The group was, in fact, completely fictitious. However, through the use of staged radio traffic, mock-up vehicles to fool air reconnaissance, occasional real units moving in and out of the group, and turned German double agents relaying false information to the German High Command made it seem that the main invasion would come at the Pas de Calais, the closest point in the English Channel (it is possible to see the White Cliffs of Dover from France at this point).

This eventually led to the redeployment of several German units, including the majority of the Panzer units in western Europe, away from Normandy. When the invasion finally came, Hitler and the High Command believed that it was a diversion and the 'real' invasion would still come from Calais.

So successful was this deception that the men who worked to create it would go on to do several diversionary 'performances' in Europe. Their exploits have recently been declassified and can be seen in the new documentary "The Ghost Army" available through PBS. Until next time take care, and thanks for reading.
