held the total of 107,000 'undesirables' already by 1935. On 26 June 1933, Reichsführer-SS Heinrich Himmler appointed SS-Oberführer Theodor Eicke the Kommandant of the Dachau concentration camp. Eicke requested a permanent unit that would be subordinate only to him, and hence the SS-Wachverbände (guard units) were formed. Eicke began his infamous tenure by issuing new orders about the killing of inmates trying to escape (Postenpflicht). He developed the first Lagerordnung, a Nazi disciplinary and penal code regulating the system of extreme disciplinary sanctions for detainees. His rules were adopted by all concentration camps of Nazi Germany as of 1 January 1934. Eicke was promoted to SS-Brigadeführer (equivalent to a major-general in the army) on 30 January 1934. Following the Night of the Long Knives, Eicke – who played a role in the affair by shooting SA chief Ernst Röhm – was again promoted to the rank of SS-Gruppenführer and officially appointed Inspector of Concentration Camps and Commander of the SS-Wachverbände. Thereafter, all remaining SA-run camps were taken over by the SS. In his role as the Concentration Camps Inspector, Eicke began a large reorganisation of the camps in 1935. The smaller camps were dismantled. Dachau concentration camp remained, then personnel from Dachau went on to work at Sachsenhausen and Oranienburg, where Eicke established his central office. In 1935, Dachau became the training center for the concentration camps service. Many of the early recruits came from the ranks of the SA and Allgemeine SS. Senior roles were filled by personnel from the Ordnungspolizei, the police who maintained order. On 29 March 1936, concentration camp guards and administration units were officially designated as the SS-Totenkopfverbände (SS-TV). In the summer of 1937, Buchenwald became operational, followed by Ravensbrück (near Lichtenburg) in May 1939. There were other new camps in Austria, such as Mauthausen-Gusen concentration camp, which opened in 1938. All SS camps' regulations, both for guards and prisoners, followed the Dachau camp model. Further development In 1935, as the concentration camp system within Germany expanded, groups of camps were organized into Wachsturmbanne (battalions) under the office of the Inspector of Concentration Camps who answered directly to the SS headquarters office and Heinrich Himmler. When the SS-Totenkopfverbände were formally established in March 1936, the group was organized into six Wachtruppen situated at each of Germany's major concentration camps. In April 1936, Eicke was named commander of the SS-Totenkopfverbände and the number of men under
