| Swiss defences in WW2 |
Switzerland, neutral since 1815, with its mixed population of German, French and Italian speakers, was a possible target for German and Italian invasion in 1940. This was Operation Tannenbaum, or in English, Operation Christmas Tree.
Hitler had made several statements regarding Germany respecting Switzerland's neutrality. Of course, at the same time, he was forging links with the National Socialist and Fascist groups within the country. In meetings, he secretly called Switzerland 'a pimple on the face of Europe' and the Swiss as a 'wayward branch of our folk'. Germany demanded the unification of all Germans into a Greater Germany; this included the Swiss Germans.
Italy also coveted Swiss territory. The area south of the Swiss alps were eyed by the Fascist government of Italy and in talks with Germany and the planning of Operation Tannenbaum, this would be annexed by Italy, while Germany would take the northern two thirds of the country.
Operation Tannenbaum would come into effect after Germany's main opponents on continental Europe were vanquished and, along with Operation Sea Lion, the invasion of Britain, was fully expected when France fell in 1940.
In preparation for any German or Italian attack, Switzerland had mobilised its army and reserves after the fall of Poland, and France and the UK's declaration of war on Germany. Switzerland also had a complex and comprehensive plan for the defence of territory, abandoning the indefensible and reinforcing the passes and valleys throughout their country.
It became clear to the German High Command that an invasion of Switzerland would bog down and occupy the Wehrmacht, using up men and resources which were needed elsewhere - Operation Barbarossa; the invasion of the Soviet Union.
