Gleiwitz incident

The Gleiwitz incident, or Gliwice incident (German: Überfall auf den Sender Gleiwitz; Polish: prowokacja gliwicka), was a false flag attack on the radio station Sender Gleiwitz in Gleiwitz (then Germany and now Gliwice, Poland) staged by Nazi Germany on the night of 31 August 1939. Along with some two dozen similar incidents, the attack was manufactured by Germany as a casus belli to justify the invasion of Poland.
