Have you ever thrown a surprise party for someone? Have you ever
bluffed playing cards? Welcome to the ranks of intelligence deceivers.
The
Trojan Horse legend survives to this day as a great deception
operation. Whether the Trojan Horse story is true, a myth, or a
metaphor, the story is fascinating. The Thought for this week deals with
the greatest deception operation in history, Operation Bodyguard
in WWII. One of the most fascinating aspects of the Bodyguard Operation
was, how did the Allies keep this massive deception operation a secret?
Over the next weeks I plan to discuss the various parts of Bodyguard
with you alternating with other topics which you may suggest and the
ongoing exigent events in world affairs.
As WWII progressed, the
Germans knew an invasion was coming from the west and the Allies were
aware they would face a stalwart set of Nazi defenses. The probability
of success for the Allied invasion was problematic. Geography set the
conventional wisdom for the location of the invasion beaches and the
cyclical weather patterns limited the timing windows for a large-scale
invasion. The Pas de Calais was the obvious geographic target for the
invading forces setting sail from England. Late Spring and early summer
presented the only reasonable times for a seaborne assault. Hitler and
the German High command were initially convinced Pas de Calais would be
the targeted beaches for an allied invasion.
To thwart any
invasion from the west, the Germans built a potent line of
fortifications and defense installations that stretched over 1,670 miles
from Scandinavia to the French-Spanish border; the Germans called it
the Atlantic Wall. The Atlantic Wall was three years in construction and
took a monumental amount of German resources away from the desperate
fighting on the Eastern front. These defenses were integrated to present
a comprehensive in-depth killing zone for any invading force.
The
defense system began beyond the beaches with mine fields and undersea
obstacles which could impale landing craft. The beaches were carefully
fit with barbed wire and minefields which would channel landing troops
into kill zones covered by artillery, mortars, and machine guns,
firepower which was pre-registered for accuracy on the kill zones. The
next defense barrier behind the beaches was an array of mutually
supporting bunkers and fortifications which could effectively redirect
and concentrate fire on specific landing force targets.
The
integration could be viewed as a defense anvil and a defense hammer. The
anvil was the network of fixed defenses. The hammer was German tank and
mechanized infantry units in reserve to deliver a coup de gras with a
smashing counterattack after the landing troops had been decimated by
smashing against the anvil.
However, there was a vulnerability in
the German defense plan. The Germans did not have enough combat units to
have the reserves in-depth along the length of the Atlanta Wall. Many
of the experienced and combat-hardened panzer (tank) and mechanized
units available for the Atlantic Wall reserve were sent to western
France to refit and rest before returning to fight the Red Army on the
Eastern Front. Therefore, the German High Command had the critical
decision how to deploy the limited number of experienced combat troops
for the Atlantic Wall reserve. The Germans needed accurate intelligence;
what location did the Allies chose for landing the invasion force and
when did the Allies plan to launch the invasion?
The Allies’
problem was even more daunting than the German challenge. The Allies did
not have a sufficient number of ships and landing craft to launch two
simultaneous invasions, Normandy and Pas de Calais. The Allies did not
have adequate troop numbers to fight on more than one invasion front.
The troops would have to attack across the beaches in sequential waves
facing the lethal Atlantic Wall defenses. If the Germans could bring
their panzer and mechanized units quickly to counterattack the Allied
attempt to establish a beachhead, the Allied forces would be destroyed
on the beaches and the invasion would fail. A failed invasion would
extend the war and result in hundreds of thousands of additional
casualties in the future. Finally, the invasion plan, Operation Overlord,
was the largest and riskiest amphibious assault in the history of
warfare. Logistically supporting the landing force during and after the
landing was a potential Achilles Heel beyond the challenge of
establishing the initial beachhead.
The mirror image problem for
the Allies to the German need to know the where and when was to not just
deny the Germans the knowledge of ‘where and when’ – but to make the
Germans believe a false’ where and when’. The massive invasion plan
required a massive deception plan to mislead and misdirect the German
High command. Operation Bodyguard was the deception component of Operation Overlord.
Bodyguard
had to be comprehensive, integrated, and had no room for errors. One
compromise in the strategic deception would lead to an unraveling of the
overall invasion plan with catastrophic consequences. Rounding out the
high probability of compromise was the reality the Allies could not
simply hide the 175,000 men preparing to assault the Nazis, the 5000+
ships needed to execute the invasion of Europe, 10,000 aircraft, and the
airborne force of over 13,000 paratroopers. One German spy gaining
information on the invasion, one German successful aerial
reconnaissance, one German successful intercept of Allied communications
could doom Overlord. The deception operation had to be credible in
every resect and present no loose ends for the Germans to detect and
exploit. Success hinged on the effectiveness of Operation Bodyguard.
Operation Bodyguard
was an amalgam of moving parts consistent with the complexity of the
Overlord plan. The major Bodyguard component operations were Fortitude
North, Fortitude South, Twenty Committee (aka Double Cross), Graffham,
and Royal Flush.
Deception in the purest sense is not just having
the enemy accept the misinformation but for the enemy to embrace the
deception as “objective truth” and then act on their belief in the
“objective truth” – and in the world of smoke and mirrors, “objective
truth” can be pure lies.
In future installments of the Thought for
the Week, we will examine how successful Bodyguard was and the reasons
for that success.
