Bring on the Reich!

POD - Stubborn Hindenburg
Hindenburg didn't appoint Hitler as Chancellor, who only acceded in January 1934, after the SA assassinated Hindenburg. Hitler appointed a 15 man 'National Council' and his two Deputy Führers were Heinrich Himmler, the hard liner and the voice of reason, Rudolf Hess.

The Second Great War
In 1938, after the annexation of Czechoslovakia, Poland invaded Germany. Hitler mobilised the Wehrmacht, and Poland was brutally invaded and placed in submission. This foolish act by Poland began the Second Great War.

Operation Sealion
After Western Europe was invaded and absorbed into the Great Reich, Hitler authorised the activation of Operation Sealion. The plan to invade Britain. After troops landed at Lyme Regis and at Ramsgate on August 3rd 1940, London was captured on September 4th, and the government and royal family were captured, although Princess Margaret escaped to Canada. The Armed Forces reformed as the British Resistance and fled to the Brecon Beacons in Wales. After Britain's official surrender on the fifth, Prime Minister Chamberlain, the Cabinet and the Queen were publicly executed in Trafalgar Square. The King commited suicide after the executions and Princess Elizabeth was moved to a concentration camp in Denmark.

The Warsaw Solution
At a conference in Augsburg, the National Council decided to send a warning to rebels and in the most brutal act of the Nazi regime, 75% of the population of Warsaw were systematically killed by the SS. All resistance movements apart from Free France and the British Resistance disbanded.
