Wrap up Questions
Five Fold
Deception Plan
 Allied leaders plan a series of
pseudo invasions to throw the
Germans off guard.
 The Germans would learn of
these faulty plans but lacked the
military intelligence to decipher
which ones were simply decoys.
Patton’s “Ghost” Army
 Allies needed to make the false
invasions seem imminent and
realistic.
 Put highly respected General
George Patton in charge of this
completely fake army called
FUSAG.
 Army had fake tanks and
everything that would make it
appear as if it was about to
embark on an invasion of
Hitler’s Fortress Europa.
Purpose of D-Day

After Germany invaded most of Europe, the Allies determined
that Germany had to be defeated.

Germany had killed millions and was willing to spread it's fear
of foreigners to even more of the world and considered
England to be the next target.

Had Germany just left England alone for a while, Hitler would
have probably succeeded in his quest for power.

The purpose was to get troops on the ground in an attempt to
liberate France.

After Allied troops gained a foothold in Normandy, they were
able to destroy much of the German occupation forces,
liberate France and continue to march across Europe and
ultimately destroy Germany.
Before the Invasion

During the first six months of 1944, the United
States and Great Britain gathered and trained
land, naval, and air forces in England.

At the same time, the Soviet Union tied down a
great portion of the enemy forces.

Allied airplanes photographed enemy
defenses, dropped supplies to the resistance,
bombed railways, and attacked Germany’s
industries.
D-Day
June 6, 1944
 The invasion would begin
on the beaches of
Normandy, France.
 The largest amphibious
force in the history of
warfare.
 Considered by some to be
the greatest military
achievement of the 20th
century.
Project Overlord

Operation Overlord was a huge assault on Normandy
beaches in France.

It was the largest focused military operation of all time.
Developments such as nuclear weapons and missiles
make it unlikely that such a concentration of ships and
assault troops will ever be assembled again.
Operation Overlord nearly failed due to weather,
operational errors, and stiff resistance by well prepared
German forces.
In the end, Overlord succeeded, the Allies surged into
France, and the fate of Hitler's Third Reich was sealed.
