Heydrich calls a break in the proceedings, and after praising Stuckart aloud takes him aside to warn him about the consequences of his stubbornness, implying that others in the SS will take an unwanted interest in his actions. When the meeting reconvenes, Heydrich steers the discussion in the direction of wholesale extermination using gas chambers. This causes consternation among some attendees, especially Kritzinger and Bühler. Kritzinger objects on the grounds that Hitler had given him personal guarantees that extermination of the Jews was not being considered. Bühler is shocked to discover that the SS have been building extermination camps at Belzec, Sobibor and Treblinka, and making preparations for the "Final Solution" under his nose.
