In the winter of 1940, Peiper accompanied Himmler on a tour of Nazi concentration camps, including Neuengamme and Sachsenhausen, with a trip to Poland to meet with Friedrich-Wilhelm Krüger, Higher SS and Police Leader in occupied Poland, and his subordinate Odilo Globocnik. The latter was tasked with deporting Jews from Polish territories annexed to Germany to Warsaw and Lublin. The tour continued in April 1940, with visits to Buchenwald and Flossenbürg concentration camps, followed by a visit to Poland to meet with SS and Police Leader Wilhelm Rediess and the SS official Otto Rasch to discuss how further "evacuations" (i.e. shootings of civilian population) could be efficiently accomplished. In early May, Himmler, accompanied by Peiper, discussed with Globocnik, the SS and Police Leader in Lublin, the mass murder of the disabled. Peiper also learned about Globocnik's work on the Lublin Reservation.
