Secret WWII Pact Between France and Switzerland Revealed

A historical discovery in 1940 has shed light on a secret wartime collaboration between France and Switzerland, a plan that remained concealed for three decades. The operation, codenamed "Operation H," was designed to provide French military assistance to Switzerland should it face an attack from Nazi Germany.

The revelation stems from documents intercepted by the German army in June 1940 near Dijon, France. Among approximately 1,800 crates of evacuated archives from Paris, German specialists found sensitive military and political papers. These documents detailed clandestine relations between France and its neighboring countries, including Switzerland.

Initially, the discovery was mistakenly linked to the town of La Charité-sur-Loire, leading to the historical episode being referred to as the "La Charité-sur-Loire affair" or "syndrome." The German high command, particularly Ambassador Hans von Moltke, meticulously analyzed the findings. The implications were significant: evidence suggested a potential violation of Swiss neutrality, raising questions about Adolf Hitler's reaction and the fate of neutral Switzerland in the heart of Europe.

Swiss historian Willi Gautschi noted in his book on General Guisan that the documents pointed to "documentary evidence of collaboration between France and Switzerland." The potential consequences were dire, as Germany could have easily occupied Switzerland. The information was shared with Hitler in September 1940, but the country's neutrality was ultimately respected, at least for the time being.

The full extent of this episode and the secret collaboration only came to light publicly thirty years later, largely due to the work of journalist and historian Georg Kreis. His 1976 book, "Auf den Spuren von La Charité," helped to unravel the historical taboo surrounding the affair and brought the complex relationship between France and Switzerland during that critical period into public view.
