Attack plans with targets marked for the cliffs east of Arromanches.
Found in a french flea market - a Top Secret 'how to' guide to D-Day.
Fascinating top secret documents and photos of the extensive planning that went into the Normandy invasion have emerged after 72 years.
Incredibly detailed plans of Nazi defences, high resolution photographs, weekly intel reports and even analysis of the German weapons they were likely to face are included in the sale.
One photo taken at zero feet shows German troops scattering across a beach as a low-level RAF aircraft sweeps by to capture the plethora of anti-landing obstacles.
Other images show the famous coastline with key cliff-top targets that had to be destroyed either before or on D-Day itself.
