The maps were distributed on the 20th May.
The most up-to-date maps for the D-Day invasion have come to light 72 years later to show the incredible detail the Allies went to to ensure victory.
The 24 original maps were drawn up just two weeks before the momentous operation and gave the military commanders the most contemporary reports of the state of the five Normandy beaches.
The charts, marked 'Top Secret', were so detailed they contained almost the exact number and positions of mines, pill boxes and other defence works the Germans had laid as part of Hitler's Atlantic Wall.
They are being sold in eight separate lots by C&T Auctioneers of Ashford, Kent, on September 7.
