The Venlo Incident was a covert German Sicherheitsdienst (SD-Security Service) engineered capture of two British SIS (Secret Intelligence Service) agents on 9 November 1939. The incident was used by the presiding National Socialist German Workers' Party government (for propaganda purposes) to link the United Kingdom to Georg Elser's failed assassination (time-bomb) attempt on German Chancellor Adolf Hitler at the Bürgerbräukeller in Munich (Germany) on 8 November 1939 and to justify Germany's later invasion of the Netherlands, a neutral country, on 10 May 1940.
