Venlo incident
The Venlo incident was a covert operation carried out by the German Nazi Party's Sicherheitsdienst (SD) on 9 November 1939, which resulted in the capture of two British Secret Intelligence Service agents five metres (16 ft) from the German border, on the outskirts of the Dutch city of Venlo. The incident was later used by the German government to link Britain to Georg Elser's failed assassination attempt on Adolf Hitler at the Bürgerbräukeller in Munich, on 8 November 1939, and to help justify Germany's invasion of the Netherlands (then a neutral country) on 10 May 1940.
