"Warsaw" is the opening song by Joy Division on their "An Ideal for Living" EP.
 It was slated for release on the album that became "Warsaw", which was originally scrapped by the band and not released until 1994.
 The song is available on a number of compilations, including "Substance".
 The song appears to be a somewhat fantastical biography of Rudolf Hess, a Nazi and Hitler's Deputy Führer, who flew to Great Britain in 1941 in an attempt to negotiate a peace between Germany and the UK, supposedly because of his disillusionment with Nazi ideology.
Deputy Führer (German: "Stellvertreter des Führers", more faithfully translated as "Deputy "of the" Führer") was the title for the deputy head of the Nazi Party.
 The only person to ever hold this title was Rudolf Hess.
Adolf Hitler (] ; 20 April 1889 – 30 April 1945) was a German politician who was the leader of the Nazi Party ("Nationalsozialistische Deutsche Arbeiterpartei"; NSDAP), Chancellor of Germany from 1933 to 1945 and Führer ("Leader") of Nazi Germany from 1934 to 1945.
 As dictator, Hitler initiated World War II in Europe with the invasion of Poland in September 1939, and was central to the Holocaust.
Helmuth Friedrichs (born 22 September 1899 in Otterndorf – died probably February 1945) was a German Nazi Party official.
 He was an important figure in the Office of the Deputy Führer and its successor the Nazi Party Chancellery.
Ruedi Walter or "Rudolf Walter", born as Hans Rudolf Häfeli (10 December 1916 – 16 June 1990) was a Swiss comedian, radio personality, and stage and film actor starring usually in Swiss German language cinema and television and stage productions.
SS-Oberabschnitt Süd, often translated as "SS-District South" or "SS-Group South", was a division strength command of the "Allgemeine-SS" and the oldest SS-division in continuous existence from the inception of the SS in the late 1920s to the downfall of Nazi Germany in 1945.
 One of its most notable commanders was Rudolf Hess who served as an early SS leader after which he was better known as the Deputy Führer of Nazi Germany.
The Party Chancellery ("Parteikanzlei"), was the name of the head office for the German Nazi Party (NSDAP), designated as such on 12 May 1941.
 The office existed previously as the Staff of the Deputy Führer ("Stab des Stellvertreters des Führers") but was renamed after Rudolf Hess flew to England in an attempt to negotiate a peace agreement without Hitler's authorization.
 Hess was denounced by Hitler, his former office was dissolved, and the new Party Chancellery was formed in its place under Martin Bormann.
Lieutenant Colonel Eugene K. Bird (11 March 1926 – October 28, 2005) was US Commandant of the Spandau Allied Prison from 1964 to 1972 where, together with six others, Deputy Führer Rudolf Hess was incarcerated.
Rudolf Walter Richard Hess (Heß in German; 26 April 1894 – 17 August 1987), was a prominent politician in Nazi Germany.
 Appointed Deputy Führer to Adolf Hitler in 1933, he served in this position until 1941, when he flew solo to Scotland in an attempt to negotiate peace with the United Kingdom during World War II.
 He was taken prisoner and eventually was convicted of crimes against peace, serving a life sentence until his suicide.
Karlheinz Pintsch (1909 -?)
 was the long serving senior adjutant to Rudolf Hess who was the Deputy Führer to Adolf Hitler in Nazi Germany.
 It fell to him to report Hess's illegal May 1941 flight to Scotland to Hitler and his recollections and notes have been the subject of debate by historians.
