During the First World War, Switzerland was destined to become a gateway for the regular transit of agents used by belligerent nations to organise conspiracies behind enemy lines. The German and French intelligence services thus engaged in a secret war in Switzerland, which became the country most subjected to foreign espionage—owing to both its geographical position and neutrality. Since the Swiss Confederation did not have any intelligence service, its police had to stand in and assume an overall counterintelligence mission. This was successful and the Swiss police managed to thwart more than a hundred plots—some of those cases being of major international significance.
