As the years went on and Himmler went up in the ranks, Hitler became even more power hungry and in 1939, he asked for a pretext for the invasion of Poland. Their idea was hated in the masterminds of Heinrich Himmler, Heydrich, and Heinrich Müller which was code named Operation Himmler. This was the brilliant idea of the false flag, which had German soldiers dress up in polish uniforms and deceive Germany and pretend that poland attacked first. Hitler then used this "Incident" to justify the invasion and authorize the killing of Polish civilians, ethnic poles, and especially Jews. The SS task forces under the direction of Himmler and Heydrich, were no repurposed as death squads and by the end of 1939 ended up killing more than 65,000 intellectuals and other civilians. These squads were also in charge of rounding up jew and others for placement in concentration camps.This was the invasion that started WWII.
