Hitler's terrifying plans to invade Britain are revealed in a cache of Nazi military documents.
They show seaside towns would have been key targets as the German army stormed ashore after the RAF had been beaten in the summer of 1940.
The North coast of Kent between Reculver and Herne Bay is identified as the location for the landing.
The packs were sent to German bases to prepare for Operation Sealion - codename for the planned invasion in autumn 1940.
Auctioneer Ben Jones said: “These are a chilling insight into what could have happened had the RAF lost the Battle of Britain.”
The detailed archive, compiled in August 1940 and reproduced in 1941, contains maps and photos of prime targets along the east coast and in the Midlands.
Black and white photos show strategic positions to capture. These include locations along the east coast such as Clacton-on-Sea, Cliftonville, Lowestoft and the River Deben.
Inside the folder on the Midlands there are detailed maps of the geography and key targets such as the Great Western Railway Station in Birmingham.
The images, gathered by German intelligence, were to give soldiers an idea of what to expect when they landed.
Some are clearly from postcards such as a black and white picture of a busy seafront at Cliftonville.
The documents are a shocking reminder of how well prepared the Germans were for a land invasion. But they needed control of the air and, thanks to the RAF, this never happened.
However, the images were used in action - by Luftwaffe pilots during the Battle of Britain as they bombarded London and strategic sites.
The Allies had a similar strategy to prepare troops for the D-Day invasion of Normandy in June 1944.
The documents are under the hammer tomorrow at Mullocks Auctions, Church Stretton, Shropshire, with a price estimate of £600.
