The plan, named after its originator, Heinrich Himmler,[1] was supervised by Reinhard Heydrich[4] and managed[5] by Heinrich Müller.[1][4] The goal of this false flag project was to create the appearance of Polish aggression against Germany, which could be used to justify the German invasion of Poland. Hitler also might have hoped to confuse Poland's allies, the United Kingdom and France, into delaying or stopping their declaration of war on Germany.[6]
