Had Hitler succeeded in his plan to invade Britain the world would now be a very different place. The United States would probably have remained neutral, leaving Germany, Italy and Russia to carve up Europe between them. There was just the small matter of destroying the Royal Air Force...
By July 1940, German forces had occupied France, Belgium, Denmark, Norway and the Netherlands. Hitler’s troops now stood a mere 21 miles from the English coast and had direct access to the Atlantic Ocean for their submarines to prey on British merchant shipping vital to the island’s survival.
In early 1940, Britain badly needed a victory to give heart to the country in the face of the seemingly unstoppable German Blitzkrieg. It came with a series of daring attacks on the Kriegsmarine as they invaded Norway and typifies the British fighting spirit at a time when Europe was a German Empire and we stood alone.

On the 1st of March 1940, Hitler ordered the invasion of Norway codenamed “Wesereubung”. The long Norwegian coastline would give his aircraft and warships an ideal base from which to attack northern Britain and the year round ice free port of Narvik would be used to transport Swedish iron ore to Germany.
