roofa show of his confidence in the occupation forces and in his government's effectiveness. By 3 October 1941, Czechoslovak military intelligence in London had made the decision to kill Heydrich. Role in the Holocaust Historians regard Heydrich as the most fearsome member of the Nazi elite. Hitler called him "the man with the iron heart". He was one of the main architects of the Holocaust during the early war years, answering to and taking orders from only Hitler, Göring, and Himmler in all matters pertaining to the deportation, imprisonment, and extermination of Jews. Heydrich was one of the organisers of Kristallnacht, a pogrom against Jews throughout Germany on the night of 9–10 November 1938. Heydrich sent a telegram that night to various SD and Gestapo offices, helping to coordinate the pogrom with the SS, SD, Gestapo, uniformed police (Orpo), SA, Nazi party officials, and even the fire departments. In the telegram, Heydrich granted permission for arson and destruction of Jewish businesses and synagogues, and ordered the confiscation of all "archival material" from Jewish community centres and synagogues. The telegram ordered that "as many Jewsparticularly affluent Jewsare to be arrested in all districts as can be accommodated in existing detention facilities ... Immediately after the arrests have been carried out, the appropriate concentration camps should be contacted to place the Jews into camps as quickly as possible." Twenty thousand Jews were sent to concentration camps in the days immediately following; historians consider Kristallnacht the beginning of the Holocaust. When Hitler asked for a pretext for the invasion of Poland in 1939, Himmler, Heydrich, and Heinrich Müller masterminded a false flag plan code-named Operation Himmler. It involved a fake attack on the German radio station at Gleiwitz on 31 August 1939. Heydrich masterminded the plan and toured the site, which was about from the Polish border. Wearing Polish uniforms, 150 German troops carried out several attacks along the border. Hitler used the ruse as an excuse to launch his invasion. On Himmler's instructions, Heydrich formed the Einsatzgruppen (task forces) to travel in the wake of the German armies at the start of World War II. On 21 September 1939, Heydrich sent out a teleprinter message on the "Jewish question in the occupied territory" to the chiefs of all Einsatzgruppen with instructions to round up Jewish people for placement into ghettos, called for the formation of Judenräte (Jewish councils), ordered a census, and
