A CHILLING map reveals how Britain would have looked if Adolf Hitler had won World War Two - with a new capital far from London and a holiday home for the dictator.
Bombshell dossiers for Operation Sea Lion - Nazi Germany's ambitious plan for a full-scale invasion of Britain - detail how the Third Reich planned an attack on the English coast in a bid to take over Europe.
Nazi planners identified five sectors of the English coast to attack - from Ramsgate in Kent to Selsey Bill in West Sussex.
They planned to land some 100,000 troops, 650 tanks and 4,500 horses in the first wave of the attack on September 21, 1940 on the southeast coast from the French ports of Le Havre, Cherbourg, Boulogne and Ostend.
Once a bridgehead had been established, a further 500,000 soldiers would have landed.
They would have begun mass territorial attacks between Ramsgate and Deal, Folkestone and Dungeness, Dungeness and Rye, Bexhill-on-Sea and Beachy Head and Brighton to Selsey Bill.

Chilling plans outlined by the Third Reich showed how confident the Germans were.
Hitler already had managed to pull off some of the greatest military campaigns that summer, capturing France and the Low Countries in Europe.
Britain was the only nation in the continent that was left to stand up against the evil dictatorship.
And German officials were convinced that an onslaught would have led to the "rapid abandonment" of the British defences south of London within just two weeks - before capturing the length and breadth of the nation.

And a map unearthed years later revealed how Britain would have looked if Hitler had managed to execute his plot.
Under German plans, Oxford - Hitler’s preferred seat of power for the Reich - was to be the new capital of Britain.
The city's historic centres were left untouched by the Germans during the devastating air raids of the Battle of Britain - believed to be part of Hitler's plan.
Plans were also to carve out the nation to form six new districts - and each of them would have had to central military control centre as big as the size of a city.
Headquarters were to be set up at Liverpool, Birmingham, Newcastle, London, Dublin and Glasgow.
Historians also believe that Ireland would have been united under the Nazis.
Meanwhile, the famous Blenheim Palace near Oxford would have turned into Hitler's secret holiday home in Nazi Britain.
Blenheim Palace is the birthplace and ancestral home of Winston Churchill - the man who led Britain against Hitler during World War Two.
It also served as the headquarters for the British MI5 during the war.
This operation aimed to eliminate the English Motherland as a base from which the war against Germany can be continued, and, if necessary, to occupy the country completely
Adolf Hitler
Documents detailing Operation Sea Lion reveal how German researchers were employed to find out details of local road systems, geography, units of measurement, money and even translations of some Welsh words, all to be used by invading forces when they landed.
They documents were found in the German naval archives after the Allies captured Berlin to end the war.
Hitler believed that Operation Sea Lion would have led to the rapid conclusion of the war, winning over Europe and establishing his absolute dictatorship.
Professor Anthony Glees, a history expert at the University of Buckingham, said the world would have looked very different with the Third Reich ruling over the continent.
He told The Sun: "If Hitler had successfully invaded Britain, we would quickly have become nazified.
"You would have a Europe dominated by a dictator, Everything would look very different.
"He would have got rid of all those politicians who were his opponents and would very quickly do to Britain what he'd done to France."
Mr Glees said that thousands of Brits, especially Jews who were listed in the German secret police the SS’s “Black Book", were to be rounded up and killed.
"Concentration camps would have been established, and Hitler would have won the war," he added.
The expert also argued that Hitler would then also have managed to carry out a successful military campaign in the East - and win against the Soviet Union.
He said: "America would have never stepped in to fight and the world would have become more isolated.
"You have effectively the world, the western part of the world divided between an isolationist America that doesn't want to be part of the global world.
"All while having the European continent under the thumb of one man and one regime."
Hitler had a clear plan to attack Britain, and the military campaign under Operation Sea Lion was seen to be "very serious".
His main objective was to cripple the RAF so it could not take the Nazi military aggression the troops crossed the English channel with ease.
The coastal zone between occupied France and England was to be dominated by heavy artillery.
And he planned to keep the Royal Navy engaged in the North Sea and the Mediterranean so that it could not intervene in the crossing.
A diversion attack was planned for two days between Aberdeen and Newcastle before the planned attack on the southeast coast.
Just like the Allied invasion of Normandy, the Germans attempted to fool the enemy into believing that the main landings were to take place elsewhere.
But the planned invasion depended on the Luftwaffe - Nazi Germany's air force - gaining air superiority by the middle of September that year.
And Hitler had failed terribly to achieve that.
The Nazi army could not secure sea lanes across the English Chanel through which troops were to be transported.
And the RAF's victory in the Battle of Britain further cast doubt on Hitler's plans.
Operation Sea Lion was put off from September 15 to September 21.

But on September 17, it was postponed indefinitely - and the ambitious military campaign never took off.
Hitler never gazed at Britain ever again.
Inside bizarre theory that Hitler fled Germany
ON APRIL 30, 1945, Adolf Hitler committed suicide by shooting himself in the head.
The maniacal Nazi boss decided to take his own life in the Führerbunker in Berlin after it became clear that Germany would lose the Battle of Berlin.
But in the months and years following his death, however, conspiracy theories circulated over whether or not he actually died - and if he escaped instead.
It all began with the Soviet Union's decision to seed two contradictory narratives in 1945: that Hitler died by taking cyanide or that he had survived and fled to another country.
Joseph Stalin himself even outright denied Hitler was dead when asked by US President Harry Truman.
It is known some Nazis used hidden escape routes called "ratlines" to flee from Germany as the Third Reich collapsed, with some finding shelter in South America.
Conspiracy theories about Hitler's death run rampant even some 76 years after he shot himself in the Fuhrerbunker.
Declassified documents unearthed by The Sun Online showed how the UK and US hunted for Hitler for ten years after the end of World War 2 as they feared he was still alive.
Secret documents reveal investigations into claims Hitler had a body double, U-boat sightings in Argentina, and claims that Adolf was photographed alive in Colombia.
One document reported to the FBI in 1947 even described a town called "Casino" near Rio Grande in Brazil which appeared to be "entirely populated" by Germans.
FBI agents interviewed an informant, who claimed to be a former French resistance fighter, who said he saw Hitler and Eva Braun sitting at a resort in the town.
Many notorious Nazis did manage to escape to South America, but it is accepted by history that Hitler and Eva Braun were not among them.
